Light stabilizer UV123 CAS 129757-67-1

Introduction

Light stabilizer UV123 is a liquid amino ether group hindered amine light stabilizer, which has the characteristics of low alkalinity, low volatility, low migration, good compatibility, good thermal stability, high light stability, etc. It can avoid reaction with the acidic components of the coating and inhibit the coating from losing gloss, discoloration, cracking and delamination.

Application 

Light stabilizer UV123 is particularly suitable for areas that come into contact with corrosive products: acid systems, flame retardant systems, sulfur and catalysts.
Light stabilizer UV123 is particularly suitable for acrylic, polyurethane, unsaturated polyester, adhesives, TPE, TPO, PVB, PVC.
Light stabilizer UV123 is particularly suitable for high temperature curing systems, acid curing paints, polyester paints, thermosetting acrylic, alkyd oxygen curing paints, acrylic oxygen curing paints, and two-component non-isocyanate paints.
Light stabilizer UV123 is used in conjunction with ultraviolet absorbers UV1130, UV571, and UV400 to significantly improve the durability of the coating. For automotive paints and industrial paints: it is recommended to add UV123 0.5-2%; UV1130 1-3%.
For decorative paints and wood paints: it is recommended to add UV123 alone 0.5-2%; or add UV1130 1-3%.
