Application<\/h3>\n

Fluorescent Brightener KS-N has a similar chemical structure to OB-1, but brightens polyester and plastic products better than OB-1, and has better compatibility with plastics than OB-1, producing very good whitening in small amounts, which is far less fluorescent than OB-1. Fluorescent Brightener KS-N is used for fluorescent brightening in all plastics especially in synthetic fibers, but also for brightening and brightening colors in paints, inks, paints and other industries.<\/p>\n
