light stabilizer 123
Light stabilizer UV123 is a liquid hindered amine light stabilizer containing amino ether groups. It has the characteristics of low alkalinity, good compatibility and high stability. Loss of gloss and chalking greatly improves the durability of the coating.
The light stabilizer UV123 is especially suitable for areas in contact with corrosive products: acid systems, flame retardants, sulfur and catalysts, etc.
Light stabilizer UV123 is especially suitable for PVB, PVC, TPE, TPO, adhesive, acrylic, polyurethane, unsaturated polyester, etc.
Light stabilizer UV123 is especially suitable for high temperature curing system, acid curing paint, polyester color paint, thermosetting acrylic, alkyd oxygen curing paint, acrylic oxygen curing paint, two-component non-isocyanate coating, etc.
The combination of light stabilizer UV123 and UV absorbers UV1130, UV384, UV400, and UV928 can significantly improve the weather resistance of coatings, and have a good inhibitory effect on loss of light, cracking, foaming, peeling and discoloration.

Description
ADSORB® 123 is a solvent-free hindered amine light stabilizer dispersion developed for waterborne coatings. Based on the NOR Hals, it is suited for coatings requiring a non-basic, non-interacting radical scavenger light stabilizer type. ADSORB® 123 fulfils most stringent durability requirements of high performance industrial and decorative applications. ADSORB® 123 is a highly effective light stabilizer in a wide range of polymers and applications including acrylics, polyurethanes, sealants, adhesives, rubbers, impact modified polyolefin blends (TPE, TPO), vinyl polymers (PVC, PVB) polypropylene and unsaturated polyesters. Moreover, BIOSORB® 123 is also recommended for applications such as automotive and industrial coatings, decorative paints and wood stains or varnishes.
