Study of the humid head, ultraviolet radiation durability of some coatings based on acrylic resins

Abstract

The influence of the chemical nature and content of some light stabilization systems based on ultraviolet radiation absorbers (UVA) TINUVIN T 1130, T 384 and hindered- amine light stabilizers (HALS) TINUVIN T 292 on the humid heat, ultraviolet radiation durability of the coatings based on acrylic polyol HSU 1168 crosslinked by olyisocyanate Desmodur N-75 have been studied. The effect of the light stabilizations systems has been evaluated. Their optimal contents in the coatings have been determined.
