What is UV-1577 CAS 147315-50-2?

UV absorber UV-1577 has the advantages of extremely low volatility and good compatibility with a variety of polymers. UV absorber UV-1577 is a very low volatile UV absorber and stabilizer. Polycarbonate and polyester can achieve better weather resistance than traditional benzotriazole UV absorbers. The low chelation tendency allows it to be used in polymer formulations containing residual catalysts.
