CIBA TINUVIN ®123 Liquid Low Molecular Weight Hindered Amine NOR Stabilizer Characterization functionality. Its low basicity is thus preventing possible interactions with acidic or other aggressive media. TINUVIN 123 is widely used to improve the weathering

performance of a variety of polymers and applications Chemical Name/ Composition Decanedioic acid, bis(2,2,6,6-tetramethyl-1-(octyloxy)-4-piperidinyl)ester, reaction

products with 1,1-dimethylethylhydroperoxide and octane

OCO(CH 2)8COO

N H OC 8H 17

Molecular weight

737 g/mole

Applications applications including acrylics, polyurethanes, sealants, adhesives, rubbers, impact

modified polyolefine blends (TPE, TPO), vinyl polymers (PVC, PVB) polypropylene

and unsaturated polyesters. Moreover, where potential interactions can occur with

other components of either the formulation or the paint system, TINUVIN 123 is particularly recommended.

Features/Benefits critical conditions when in contact with aggressive media including acids, flame

retardants, sulfur, and catalyst residues. Its liquid form provides ease of handling and

incorporation as well as dosing accuracy. It is compatible with a wide array of

substrates as well as a variety of co-additives including antioxidants, processing

stabilizers, UV absorbers, and other hindered amine stabilizers or optical brighteners,

antistat agents, fillers, colorants or others.

Guidelines for use

substrate as well as performance requirements. In many substrates a synergistic

performance is observed when used in combination with a ultraviolet light absorber.

For optimum effectiveness, adequate base stabilization of the polymer is necessary

to prevent thermal oxidation.
