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.
