Fluorescent Brightener KSN's chemical structure is similar to OB-1's but has much better whitening effects than OB-1 on polyester fiber and plastics. It has a better compatibility in plastics, highly whitening effects. KSN has a good resistance to high temperature as well as excellent resistance to light and weather. It is applied to whiten polyester, polyamide and polycarylonitrile fibers, used in film, plastic pressing & injection process. KSN is also suitable for whitening high polymers and could be added at any point during synthesizing.
