开封后的密封胶应盖好盖子，防止空气接触导致固化。
二、密封胶的使用方法1. 准备工作在使用密封胶前，需要确保使用面干燥、清洁。
可以使用清洁剂或酒精擦拭，并待其完全干燥。
2. 填充缝隙将密封胶挤压到缝隙中，用胶尖或刮刀将胶水均匀填满整个缝隙。
注意控制胶水的用量，以免过多造成浪费或难以清理。
3. 平整表面使用刮刀将胶水表面平整、光滑。
可以在密封胶上喷洒少量清水，利用水的润滑作用平整胶水，使其达到更好的效果。
4. 干燥时间在完成密封后，根据密封胶的说明书等待一定时间，以确保胶水完全干燥和固化。
三、常见问题与解决方案1. 胶水未固化若胶水未固化，可能是由于环境湿度过高或温度过低。
此时可使用加热器或风扇加速干燥过程，或更换具有低温固化特性的密封胶。
2. 胶水固化时间过长如果需要缩短胶水固化时间，可以增加环境温度，或使用硬化剂。
同时，也可以减少胶水的施工量，以加快固化过程。
3. 涂覆不均匀在涂覆胶水时，如遇到不均匀问题，可使用刮刀或胶尖进行修整和调整，确保涂覆的表面平整。
四、安全使用注意事项1. 使用安全工具在使用密封胶过程中，应佩戴手套、护目镜等安全工具，避免胶水溅入眼睛或对皮肤造成刺激。
2. 通风良好使用密封胶时，确保使用环境通风良好，以防止胶水的气味对人体造成不适。
3. 远离火源密封胶多含有易燃成分，使用时需远离明火或高温热源，以免引发火灾事故。

The windload stresses on the facade are transferred through the structural silicone sealant to the structure of the building. The structural silicone sealant must maintain its adhesive and cohesive properties in order to support the panels under windload.Only silicone sealants are suitable for use in structural glazing applications. A considerable amount of time has been spent developing and testing silicone sealants to meet the needs of structural glazing application. Whenever a silicone sealant is used to structurally bond facade panels, a comprehensive quality control procedure must be established to assure the smooth, efficient, trouble-free completion of the project.Specific quality control procedures must be followed on all structural glazing projects in order to obtain a Dow Corning Structural Warranty.Structural Joint DesignStructural BiteStructural bite is the minimum width or contact surface of the silicone sealant on both the panel and the frame. The structural bite requirement is directly proportional to the windload on the building and the size of the glass. The higher the design windload and the larger the size of the glass, the greater the structural bite requirement. The structural bite must be sized appropriately to allow the windload on the glass or panel to be transferred to the structure. The structural bite for windload (live load) is calculated using the specified windload, glass or panel dimension and sealant design strength of 20 psi (140 kPa).Structural Bite CalculationFollowing is the calculation used to determine the required structural bite dimension:Bite (in) = 0.5 x short span length (ft) x windload (psf)12 in/ft x sealant design strength (20 psi)For example, a 4' x 8' lite of glass, exposed to a 60 psf windload requires a silicone bite of 1/2". Always round up to the nearest 1/16" and never round down.Bite (mm) = 0.5 x short span length (mm) x windload (kPa)strength(140kPa)designSealantFor example, a 1219 mm x 2438 mm lite of glass, exposed to a 2.87 kPa windload requires a silicone bite of 13 mm. Always round up to the nearest millimeter and never round down. DeadloadIn unsupported deadload designs, the weight of the panel places constant load on the sealant. Dow Corning structural sealants can support the weight of the panel or glass when used within the following guidelines:* For DOW CORNING795 Silicone Building Sealant, DOW CORNING 983 Silicone Glazing and Curtainwall Adhesive/Sealant, DOW CORNING 993 Structural Glazing Sealant and DOW CORNING 995 Silicone Structural Sealant the allowable deadload design strength is 1 psi or 7 kPa (700kg/m2)The weight of the panel divided by the total silicone contact area must not exceed 1psi, the deadload design strength of the sealant. Insulating glass unit manufacturers require deadload support for their insulating glass units.The deadload structural bite requirement (for 4 sided structural glazing case) is calculated asfollows:Bite= weight of glass in lbsglass perimeter in inches x sealant deadload design strength (1 psi)For example, a 4' by 8' lite of monolithic glass at a weight of 3.3 psf will have a weight of 105.6 lbs and a glass perimeter 288 inches. Based on a 1 psi deadload design strength, a bite of 3/8" is required.Bite= weight of glass in kgglass perimeter in meters x sealant deadload design strength (700 kg/m2)For example, a 1.219 meter by 2.438 meter lite of monolithic glass at a weight of14.8 kg/m2 will have a weight of 43.97 kg and a glass perimeter of 7.314 meters.Based on 700 kg/m2 deadload design strength, a bite of 9 mm is required.DEAD LOAD FORCEGlueline ThicknessProper glueline thickness facilitates the installation of sealant and allows reduced stress on the structural joint resulting from differential thermal movement. A minimum glueline of 6mm (1/4") is required, but as the structural bite increases, the glueline should be increased to allow the sealant to be applied easily and the panel to expand and contract when subjected to thermal movement. If structural bite requirements exceed 19mm (3/4") , the glueline thickness should be increased to a dimension greater than 6mm (1/4"). To facilitate filling of the structural joint, the bite to glueline thickness ratio should be maintained at 3 to 1 or less.All panels that are structurally glazed undergo repeated expansion and contraction due to variation in temperature. Glueline thickness must be properly designed to accommodate these movements. The thermal movement can be calculated for any panel or framing member if the length of the material, material type, (e.g. glass, aluminum) and coefficient of thermal expansion (CTE) is known.Joint movement for a particular panel can be calculated as follows:Movement (mm) = panel length (mm) x CTE (mm./mm./ o C) x temperature change (o C)For example, for a 2000mm by 2000mm high lite of glass fixed at the sill and a temperature change of 60o C, glass with a CTE of 9 x 10 -6 will show movement of 1.08 mm. Aluminum with a CTE of 23.2 x 10 -6 will move 2.78mm Differential movement between the glass and aluminum will be 2.78mm minus 1.08mm or 1.7mm.The dimension of glueline required (a) for the differential movement (b) can be calculated using the Pythagoras Theorem. Likewise, the allowable movement (b) for a particular glueline dimension (b) can also be calculated. The new glueline thickness (c) is limited by the movement capability of the sealant in shear in a structural joint configurationFor the example discussed above where differential movement of 1.7mm (b) is expected, and the sealant has an original glueline thickness of 6mm (a), the sealant will elongate to a new glueline thickness of 6.236mm (c). Extension of the sealant from 6mm to 6.236mm will be 4%.For DOW CORNING 995 Silicone Structural Adhesive and DOW CORNING 795 Silicone Building Sealant, maximum extension from thermal expansion is 15% in any structural silicone joint. For Dow CORNING 983 Silicone Glazing and Curtainwall Adhesive/ Sealant and Dow CORNING 993 Structural Glazing Sealant, maximum extension from thermal expansion is 10% in any structural silicone joint. The lower allowable movement capability in structural joints is due to the joint design, where the joint width, or glueline is less than the joint depth or structural bite. This is the reverse situation to weatherseals, which have higher movement capability.Note: Coefficients of Thermal Expansion Values for common building materials are available in the weatherproofing section of this technical manual.Note: The direction of the panel movement would also need to be considered. Consider whether thermal movement will take place in one direction due to the setting blocks preventing any downward movement of the glass panel or in the case of an unsupported system where the thermal movement can be taken by the glass in both directions. This will need to be taken into consideration when designing the sealant joint dimensions.Structural Glazing GuidelinesFollowing are general guidelines that should be followed for all structural glazing applications. All exceptions must be handled on a project specific basis and documented in writing by the Dow Corning Technical Service Representative.* The structural bite must be a minimum of 6mm (1/4").* The glueline thickness must be a minimum of 6mm (1/4").* The structural bite must be equal to or greater than the glueline thickness.* The bite to glueline ratio must be between 1:1 and 3:1.* The structural sealant joint must be able to be filled using standard sealant application procedures.* The joint design must allow the sealant exposure to air so that it can cure and obtain its ultimate physical properties.* The structural sealant joint must be fully cured and adhered prior to removing temporary fasteners in the field or moving curtainwall units in the shop.All exceptions to these guidelines must be reviewed and approved by a Dow Corning Technical Service Representative.Substrate SuitabilityWhen selecting aluminum substrates for structural glazing, the joint design and adhesion of the structural silicone must be considered. A flat surface with no gasket races, key slots, serrations or other irregularities is required. Some off-the-shelf extrusions may not be suitable for all structural glazing applications. The width of the extrusion must be adequate to achieve the calculated minimum structural bite with a suitable spacer attached.Extruded mill finish aluminum is not an appropriate surface for structural silicone application due to poor adhesion. The graphite lubricant used in the extrusion process causes a highly variable surface to which adhesion is not always predictable. Therefore, aluminum must have a minimum of an alodine finish for structural glazing applications. Anodizing and thermal set paints such as fluorocarbon and polyester powder coat, are also suitable aluminum finishes. In addition high-grade stainless steel (316) can also be specified, as verified by past adhesion tests and actual projects.Where substrates with non-typical surface finishes are specified, the customer should contact Dow Corning for specific advice. Discussion will need to take place on the durability of any substrate finish prior to its acceptance and use in structural applications. Independent confirmation of the substrates stability/durability may be required. Dow Corning's adhesion testing procedures, which confirms the adhesion characteristics of the sealant to the substrate, does not in any way verify the durability of that substrate. Contact your Dow Corning representative for further information.In addition to suitability of substrates for adhesion, gasket and accessory materialsmust be compatible with Dow Corning Sealants. The spacer material used in structural glazing must be fully compatible with the structural silicone. Based onhistorical testing, materials such as silicone, alcryn, polyurethane foam tape andmany vinyl extrusions are found to be compatible for full contact with structural silicone. Other materials such as EPDM, neoprene, santoprene, krayton and othersimilar organic materials are found to cause discoloration of light colored sealant.These materials are often approved for incidental contact with the structural siliconebut are not approved for full contact as a structural spacer material. Because slight discoloration of the lighter colored sealant will occur, typically only dark coloredsealants will be recommended for contact with these organic extrusions. Where discoloration is severe, even incidental contact may not be approvedProject Review ServicesDow Corning professionals are available to assist you in selecting the best sealant for your specific application. All Silicone Structural Glazing applications using DOW CORNING Adhesive/Sealants must be reviewed on a project specific basis by our technical service staff prior to any product selection. The review and testing must be successfully completed along with factory or site QA documentation before Dow Corning will issue a warranty. A project submission form is included with this manual for your use. Additional forms are available from any Dow Corning representative. The following services are offered by Dow Corning. Product RecommendationsAfter reviewing project drawings and specifications and having performed laboratory testing, Dow Corning will assist in the selection of the correct DOW CORNING sealant/primer and/or surface preparation for the specific application.Print ReviewGuidelines for silicone structural glazing details are provided in this section. Dow Corning must review all structural details before any approval or acceptance is given. Typical horizontal and vertical details, plus any non-typical details should be submitted for review. Also provide elevations indicating glass dimensions and design windload values for the building. Dow Corning has found that a few underlying principles are critical to consider in virtually all joint designs using silicone sealants. Dow Corning will review joints for compliance with these underlying design principles, provide suggestions or changes and/or identify limitations of the designs. It will also allow Dow Corning's technical staff to check that all components that will need to be tested as part of the project review have been supplied. This will include bonding substrates, spacers, setting blocks, gaskets etc.Adhesion TestingDow Corning will evaluate the adhesion of our product to materials representativeof those to be used on the job (i.e., glass, metal, masonry, composites, etc.) using amodified ASTM C794 peel adhesion test. All samples submitted for testing shouldbe a minimum of 200mm (8 in) in length. For example, for aluminum extrusions,supply one 200mm (8 in) sample for each sealant to be tested. For glass, onestandard 300mm by 300mm (12" by 12") sample is sufficient. Upon completion ofthis testing, Dow Corning will forward in writing, product recommendation, surface preparation, and primer recommendation (if needed). Testing takes 4 weeks fromreceipt of samples.Compatibility TestingChemically incompatible glazing accessories (gaskets, spacers, setting blocks, etc.) can lead to sealant discoloration and/or loss of sealant adhesion to the substrate. To ensure a product's suitability, Dow Corning tests the compatibility of job site representative accessory materials with its silicone sealants using ASTM Cl087. For each sealant to be tested, supply 100 mm (4 in.) minimum length of the gasket, spacer or setting block. Results of the compatibility test will be forwarded in writing. Testing takes 4 weeks from receipt of samples.Non-Stain TestingIf natural stone is being used on the project, Dow Corning can test and evaluate the performance of its sealants to determine if fluid in the sealant has the potential to migrate into porous substrates such as granite, marble, travertine and limestone. Job site representative samples of the stone need to be tested using a modified ASTM C1248 procedure. For each stone type and sealant to be tested, supply two samples of the dimension 25mm by 75mm (1" by 3") the thickness of the stone. Larger samples can be cut for testing. Testing takes approximately 35 days from receipt of samples.Other Test RequirementsDow Corning can accommodate special, non-standard testing requirements. Please consult your local Dow Corning Representative at the beginning of the project to determine whether Dow Corning is capable of such testing services. Dow Corning may charge a service fee for non-standard testing.Any review, recommendation, or statement, made on behalf of Dow Corning relating to an engineering design, architectural drawing, product formulation, end-use specification, or similar document is limited to the knowledge of product properties as determined by laboratory testing of material produced by Dow Corning. Any comments or suggestions relating to any subject other than such product properties are offered only to call to the attention of the engineer, architect, formulator, end-user or other person, considerations that may be relevant in his/her independent evaluation and determination of the appropriateness of such design, drawing, specifications, document or formula. Dow Corning assumes no responsibility for the commentsor suggestions relative to subjects other than such product properties, and expressly disclaims any warranty or responsibilities for them.Classification of Silicone Structural GlazingGlazingStructural2-SidedThis method uses structural silicone sealant to support the glass on two sides (eithervertical or horizontal edges) and utilizing mechanical support on the other two sides.Two-sided structural glazing can be fabricated in factory or on site.4-Sided Structural GlazingGlass is supported on all four sides with structural silicone. Structural silicone is used for bonding all four edges of the glass to the support frame, and the deadload can either be supported mechanically by a fin and setting block or by the structural silicone. It is generally recommended that four-sided structural glazing be performed in shop.Application Methods for Structural Glazing SystemsFactory (Shop) GlazingCurtain walls assembled in a factory environment are assembled in individual units. This system is referred to as unitized curtainwall. Factory construction of the curtainwalls provides a controlled environment where proper surface preparation and sealant application procedures can be maintained, and quality control programs can be implemented and documented. After the units are assembled and sealant has been allowed to fully cure and develop adhesion, units are shipped to the construction site where they are erected onto the building structure.Site (Field) GlazingSite glazing is a method that applies structural sealant directly at the construction site. Panels are attached to the mullions and transoms, which are already attached to the structure. Site glazing is suitable for 2-sided structural systems, but it is generally recommended that 4-sided systems are factory glazed.Temporary mechanical fasteners are required to firmly hold and prevent movement of the panels until the structural sealant is fully cured and adhered.NOTE: Special attention to cleaning and sealant application is required under the following conditions:* Occurrence of severe wind during application may cause undue stress on the curing structural silicone* Extremely high or low temperatures - optimum application temperature range is 10-35o C (50-95o F). For applications below 10o C (50o F), the potential for dew point and frost must be considered. For application in higher temperatures, sealant must not be applied when substrate temperatures are in excess of 50o C (120o F)* Rain contaminated joints - remove all moisture from the substrate surface, then solvent clean, prior to glazing.Structural Glass Systems (Bolted Glazing)The structural glass or bolted glass system generally has holes drilled at each corner of a glass element and a bolt is used to provide mechanical support for the glass and fixes the glass facade to a metallic structure which is secured to the main structural member of the building. A high quality silicone sealant is then used to provide the weatherseal between the glazing elements.As a result of recent developments in silicone sealant technology insulating glass units can also be installed using bolted glass technology. In this system a high performance silicone insulating glass sealant is used to produce the hermetic edge seal of the insulating glass units. Silicones are used due to their excellent resistance to ultra violet, which would attack organic based sealants. Furthermore, high performance, structurally capable silicone insulating glass sealants used as the hermetic edge seal can dispense with the need to drill the external glass element of the insulating glass unit. In this design the internal glass is bolted back to the main structure, while the external glass is structurally bonded to the inner glass around its perimeter.One of the latest developments in structural glass design is the elimination of the bolted system and the need to drill the glass by using structurally bonded patch plates as an alternative. Dow Corning's range of structural adhesive sealants enable the designer to do away with the cost of drilling of holes in glass and the use of very expensive stainless steel spider systems. This results in a system that has a reduced cost of manufacture, increased visibility and improved aesthetics.Structural Glass Systems are often referred to as structural glazing, which is often confused with structural silicone glazing, as both techniques use this generic term. Therefore, architects and specifiers should be sure of which system is being offered.Total Vision Systems (Fin Glazing)Total Vision or fin glazing is a system that is used to maximize the area of glass at the front of the building, reducing the visible mechanical fixings and increasing the unobstructed vision area of the facade. Total vision glazing is a two-sided structural glazing system, in which the glass is normally mechanically fixed at head and sill and the vertical edges are structurally attached to glass fins or mullions. The glass is bonded to the glass fin using Dow Corning structural silicone sealants. The structure is then made watertight using Dow Corning weathersealing sealants. This technique is widely used for lobbies, showrooms and racetracks where the unobstructed visibility is an advantage.Structural Attachment of Non-Glass MaterialsMaterials besides glass have been successfully attached to buildings with silicone sealants for many years. The benefits of structural silicone have been used with materials such as thin stone panels including granite or marble, ceramic tile, plastic and aluminum composite materials. In all cases, Dow Corning has performed extensive testing of specific materials prior to approving the use if its sealant as a structural adhesive. The durability of the non-glass material must be evaluated to determine its suitability for this application.Certain materials such as plastics may have high coefficients of thermal expansion that may cause undue stress on the structural silicone and/or bowing of the panels. Dow Corning must review all designs whether glass or non-glass materials where its sealants are used as structural adhesives.For aluminum composite materials that are mechanically attached around the perimeter and the sealant is used to attach an aluminum stiffener, Dow Corning permits glueline thickness dimensions of less than 6 mm (1/4"). In this application, there is a negligible amount of differential movement between the two aluminum components and shear stress on the sealant is minimal.。
