UV ABSORBER UV-99-2

UV 99-2 is a liquid UV absorber of the hydroxyphenyl-benzotriazole class developed for coatings. Its very high thermal stability and environmental permanence makes it suitable for coatings exposed to high bake cycles and/or extreme environmental conditions. It has been designed to fulfill the high performance and durability requirements of automotive and industrial high quality finish. Its broad UV absorption allows efficient protection of light sensitive base coats or substrates such an wood and plastics.

Performance and use
UV 99-2 is recommended for coating such as: trade sales paints, especially wood stains and clear varnishes general industrial applications high-bake industrial systems(e.g.coil coatings) The performance provided by UV 99-2 is enhanced when used in combination with a HALS stabilizer such as LS-292 or LS-123. These combinations improve the durability of coatings by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, chalking, color change, blistering and delamination.
