Application Scope
TINUVIN 900 can be used in: automotive paints, coil coatings, powder coatings
TINUVIN 900 can be compounded with hindered amine light stabilizer, which can protect the gloss retention, chalk resistance, discoloration resistance and delamination resistance of the coating. Light stabilizers can be added to two-component automotive paints and varnishes; however, it can be seen from experiments that it is recommended to add it to the top layer of paint to achieve the best results.
Recommended addition amount (based on the solids content of the coating system)
1.0-3.0% TINUVIN 900
Compounding
0.5-2.0% TINUVIN 292/ TINUVIN 123
