UV Absorbers

SONGSORB® 3260 PW is a strong absorber of ultraviolet light in the 300-400nm region and has a high degree of photostability. It has a greater absorption of longer wavelengths than SONGSORB® 1000 and better compatibility with polyolefins, lower volatility, and suppressed ionization of the phenolic group. It is less affected by alkalinity, is less likely to discolor with metals, and has less effect on metal driers and metal catalysts due to the higher dissociation constant of SONGSORB® 3260. Recommended for use levels of 0.2 - 1.0% in PP, PE, polybutylene, polyesters, and coatings. Can be used in combination with SONGNOX® Antioxidants and SONGLIGHT® Hindered Amine Light Stabilizer to optimize performance in outdoor use. FDA listed in 21 CFR 178.2010, Antioxidants and/or Stabilizers for Polymers.
