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.
