Benetex® OB

Allgemeine Produktkreise: Additive -- Optical BrightenerGeliefert von: Mayzo
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:
  • 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
