Application

A combination of Lotsorb UV 3030 significantly reduces discoloration caused by exposure to light. Recommended dose: 0.20 –0.60% 

A 1 : 1 combination of Lotsorb UV 3030 and Lotsorb UV 5050H significantly improves the heat stability and the  fastness to light and weathering. Recommended dose: 0.2 –0.6% 

Lotsorb UV 3030 provides completely transparent polycarbonate parts with excellent protection from  yellowing, while maintaining the clarity and natural colour of the polymer in both thick  laminates and coextruded films.
