Fluorescent whitening agent KSN has a similarchemical structure to OB-1, but its whitening effect on polyester fibers andplastic products is better than OB-1, and its compatibility with plastics isbetter than OB-1, so it is rarely used.
It can produce a very good whiteningeffect, which is far inferior to OB-1.
KSN not only has excellent hightemperature resistance, but also has excellent sun resistance and weatherresistance. Fluorescent whitening agent KSN is also suitable for whiteningpolyamide, polyacrylonitrile and other polymer fibers; it can also be used infilms, injection molding and extrusion molding materials. Adding KSN at anyprocessing stage of synthetic polymers has great benefits. Good whiteningeffect.
