UV Absorber

Description

Characteristic

Application

Sunsorb-329 is a high effective light stabilizer for variety of plastics and other organic substrates. It exhibits strong absorbance in the 300-400 nm region and minimal absorption in the visible region >400nm. Sunsorb-329 can be used in combination with HALS or antioxidant. Such blends can achieve synergistic results. It can preserve the original appearance and physical integrity of films. Fibers, etc during outdoor weathering.
