Worldwide consumption of anticorrosion coatings estimated at ca. 1.1 Millions MT, with a value of ca. $ 5 Billions in 2001. M&PC coatings represent 4% of the global coatings volume, but 8-9% of the total value.
• Good surface preparation required • Curing rate depends upon temperature. • Chalking when exposed to sun light
• Over coat-ability limitations Minimum & maximum intervals between layers to be respected

Epoxy Resins are essential raw materials for Marine & Protective Coatings. Epoxy systems offer an outstanding balance between performances [durable corrosion protection] and costs.
Key Performances requirements Resistance to corrosion
Chemical resistance
Mechanical resistance, e.g. abrasion
– Topsides and external superstructures
– Offshore oil drilling platforms

Typical curing agents used in M&PC
• • • • • • • Curing agents [mostly based on amine chemistry]. Polyamidoamines [VersamideTM type] Amidoamines Epoxy - Amine adducts Mannich bases [Faster cure] Phenalkamines [Low temperature cure] Typical accelerators Tertiary amines e.g. AncamineTM K54 type Alkyl phenols Remarks: Induction time needed with some curing agents to overcome the limited compatibility with epoxies and to minimize the “blushing effect”. Curing agents frequently used at under-stoichiometric levels to minimize blushing [typical NH / epoxy stoichiometry = 80%]
• Bisphenol A epoxy resins & solutions – D.E.R.™ 331™ – D.E.R. 337X80 – D.E.R. 660X80 – D.E.R. 671 – D.E.R. 671X75 – D.E.R. 671XB70 • Bisphenol F epoxy resin – D.E.R. 354 • Epoxy novolac resins – D.E.N.™ 425 Best chemical – D.E.N. 431 resistance – D.E.N. 438X80
(Pot life depends on temperature, quantity, type of resin and hardener)
Modifiers e.g. hydrocarbon resins or reactive diluents can be used

The role of epoxy coatings is to protect against corrosion each part of ships, which are continuously exposed to severe conditions, i.e. sea water immersion, splashes of sea water, UV rays – maintain the value of the assets – ensure vessel safety – protect cargoes, e.g. grain or liquids

Desired Properties of M&PC Coatings
Each end-use requires an optimum balance between: – Ambient application window – Ease of applying [ spray, brush, roll ] – Solids content, VOC content – Film thickness – Drying time – Sufficient hardness / flexibility – Edge covering – Impact resistance – Overcoating time window, – Long term corrosion protection – Long term adhesion, adhesion in wet environment e.g. in water immersion conditions – Resistance against chemicals { acids, solvents, caustic,… }

Trend towards Liquid Epoxy Resins and Semi-Solid Epoxy Resins expected in Europe due to more stringent VOC regulations
