Benetex OB Plus 2,5-thiophenediylbis(5-tert-butyl-1,3-benzoxazole) 7128-64-5 Mayzo Fluorescent Whitening Agents / Obtical Brighteners Acrylics/ Acrylates Vegetable based Polyesters PU - Prepolymers Benetex® OB Plus Optical Brightener, Fluorescent Whitening Agent Heat resistant, solvent soluble, chemically stable fluorescent whitener that provides brighter looking colors. 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. 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. Advantages: Does not require additional milling in coating and ink applications More easily dispersed than other optical brighteners More efficient than other optical brighteners Brilliant, bluish white effects that compensates for yellowing Good light fastness and low volatility Exceptional whitening properties Highly compatible with a wide range of organic substrates and solvents Excellent resistance to heat Useful as a tracer in clear coatings In combination with dyes, produces particularly bright shades Heat resistant, solvent soluble, chemically stable fluorescent whitener that provides brighter looking colors.
