Product Description
Fluorescent Brightener Optical Brightener Whiting Agent For Linen And Cotton Wool Brightening
Introduction
It 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. 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 ideally suited for: 1.) screen printing applications where reduced clogging of equipment is critical to increase productivity and 2.) clear-coat applications where efficiency of dispersion and a smooth coating appearance is neededis a heat resistant, solvent soluble, chemically stable fluorescent whitener that provides brighter looking colors.

Property
Optical Brightener is a disulfonic distyrylbiphenyl biphenyl compound, which is the most excellent brightener used in detergent industry. It can soluble in water easily and has better whitener effect on cellulose fiber, polyamide and proteinic fiber at room temperature. It has high brighten intensity on cotton cloth as much 2.7 times diphenylethylene tristriazine derivatives, and has well optical blue color monitor, dissolve and disperse properties. It has extremely high stability with hypochlorite sodium; it is a bleaching resistant optical brightener.
Application
Can be used to impart excellent brightness to various thermoplastics, including: polyvinyl chloride, polyethylene, polypropylene, cellulose acetate, polystyrene, polycarbonate, acrylics, polyolefins, adhesives, polyurethane, linear polyester, and polyamides. This product is significantly more efficient than other optical brighteners.
Storage
