Chemk UV 99-2 is a liquid UV absorber of the hydroxyphenyl-benzotriazole
class developed specifically 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 cost/performance and durability
requirements of trade sales and industrial coatings. Its broad UV
absorption allows efficient protection of light sensitive substrates such as
wood and plastics.

The performance provided by Chemk UV 99-2 is enhanced when used in
combination with a HALS stabiliser 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.
