| 介绍 | Benetex® OB 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. Applications: Thermoplastics - Benetex® OB 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. Coatings - Benetex® OB provides an excellent means to determine coverage of either conventional or UV cure coatings. Small amounts act as a tracer which, when viewed under a black light, indicate whether or not uniform coating coverage has been achieved. This is especially useful for clear coatings where coverage can be difficult to determine by conventional means. Benetex® OB can also be used to offset the yellowness of coatings to yield a whiter appearance. Printing Inks - Benetex® OB may be used in printing inks to facilitate the quick identification of security bonds, and also as a safeguard against forgeries (bank notes). Benetex® OB may also be combined with dyes to produce particularly bright shades. The effect is especially pronounced in pastel shades. Man-made fibers - Benetex® OB imparts a lightfast brightness with good textile fastness properties to both PVC and acetate fibers. Main applications - Include fibers, molded articles, films, sheets, clear lacquers, paints, printing inks, and synthetic leather. Advantages:
