Optical brightener FP-127 is a heat-resistant, solvent-soluble, chemically stable optical brightener that provides better color. It is used to offset the yellow color of the polymer and produce a whiter appearance. Optical brighteners change the wavelength of light by absorbing ultraviolet light, and then emit light in the form of fluorescence. It 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. This fine powder form is very suitable for:
1.) Reducing the clogging of the equipment is essential to increase productivity and
2.) It is essential for the application efficiency of the clear coating to disperse and smooth the appearance of the coating.
