Benetex® OB

Overview

Benetex OB (7128-64-5) is a heat resistant, solvent soluble, chemically stable fluorescent whitener that provides brighter looking colors.  It is used to offset the yellowness of a polymer and to yield a whiter appearance.  Optical brighteners create brilliance by absorbing UV light, modifying the wavelength of the light and then emitting the light in a fluorescent fashion.  Benetex OB can also be used as a tracer in various applications and as an optical brightener in thermoplastics, coatings, printing inks, dyes, man-made fibers, waxes, fats, and oils.
