SONGSORB^® 3270 PW

SONGSORB^® 3270 is a strong absorber of ultraviolet radiation in the 290 - 500nm region and has a high degree of photostability. Exhibits good initial color, low volatility, excellent stability to heat and light, superior wash fastness, and resistance to gas fading. It's particularly suitable for PP and PE, as well as cold cured polyesters, polyurethanes, dyes, and pigments. The low pKa and high hindrance of the phenolic group result in low sensitivity to metal containing ingredients in the polymer formulation (catalysts residues, metallic dries, etc). Can be used in combination with SONGNOX^® Antioxidants and SONGLIGHT^® Hindered Amine Light Stabilizer to optimize performance in outdoor use.
