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
CAS Number
Structure
TINUVIN 123 N H 17C 8O H
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.
