Technical Datasheet | Supplied by M Chemical
GUARD DOG™ UV328 by M Chemical is 2-(2’-Hydroxy-3,5’-di-t-amylphenyl)benzotriazole. Acts as a UV light stabilizer. It has exceptionally strong and broad-range of UV absorption properties in 270 - 380 nm region with low color contribution. Provides excellent protection to plastics. It has high degree of inherent light stability and low volatility. It helps to preserve the original appearance and physical integrity of polymer systems during outdoor weathering. This product may also be used in conjunction with other light stabilizers of HALS class to give plastics a superior protection against gloss reduction, cracking, color change, blistering, chalking and delamination. It is only recommended for room temperature and low temperature cured formulations such as air dried alkyd or moisture cured PU based systems. GUARD DOG™ UV328 exhibits excellent compatibility with styrene, acrylic, PVC, PU, polyolefins, unsaturated polyesters, PVB, polyacetals, elastomers and engineering polymers. Recommended dosage rate for plastics is less than 1%.
