Fluorescent Brightener KSN is a fluorescent brightener of benzoxazole with a yellow-green powder appearance and a blue-violet fluorescent light. It has good compatibility, does not precipitate easily, adds little and has a good whitening effect, and also has excellent heat and light resistance. The fluorescent brightener KSN has a similar chemical structure to the whitening agent OB-1 and is better soluble than OB-1 for plastics and polyester fibres, with better whitening effect. It is suitable for polyester, polyamide and polyacrylonitrile, especially for engineering plastics and synthetic fibres.
FWA KSN's chemical structure is similar to FWA OB-1's but has much better whitening effects than OB-1 on polyester fibres and plastics,its compatibility with plastics is better than OB-1's too,highly whitening effects is available with only small dosage,KSN has a good resistance to high temperature as well as excellent resistance to light and weather.Applied to whiten polyester,polyamide and polycarylonitrile fibres,used in film,plastic pressing & injection process too.Suitable for whitening high polymers and could be added at any point during synthesizing
