SONGSORB 3270 PW

* SONGSORB 3270 ® is a strong absorber of ultraviolet radiation in the 290~400? region and has a high degree of photostability – photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy.
* Exhibits good initial color, low volatility, excellent stability to heat and light, superior wash fastness, and resistance to gas fading.
* Is particularly suitable for polypropylene and polyethylene 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 polymer formulation – catalysts residues, metallic driers, etc.
* Can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use.
* Should be stored in a cool, dry, well ventilated area, away from direct sunlight.
