- Applications
Plastics – Benetex OB is used to impart excellent brightness in plastics, including PVC, polyethylene, polypropylene, cellulose acetate, polystyrene, polycarbonate, acrylics, polyurethane, linear polyester, and polyamides (nylon). Coatings – Benetex OB provides an excellent means to determine coverage of either conventional or UV cured 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 effect 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 provide a whiter appearance. Printing Inks – Benetex OB may be used in printing inks to facilitate the quick identification of security bonds, and also in bank notes as a safeguard against forgeries. The product may also be combined with dyes to produce particularly bright shades, especially pronounced in pastel shades. Synthetic fibers – Benetex OB imparts a lightfast brightness with good textile fastness properties to PVC and acetate fibers. Adhesives & Sealants – Benetex OB is used to increase whiteness and brightness, and is also useful as a tracer to ensure that uniform coverage by the adhesive or sealant has been achieved. Main applications include fibers, molded articles, films, sheets, clear lacquers, paints, printing inks, and synthetic leather.
- Guidelines for Use
Recommended loading concentrations for Benetex OB range between 5 and 10 ppm (0.0005- 0.001%) in unpigmented polyolefins and between 50 and 1000 ppm (0.005-0.1%) in other substrates. The product can be used alone or in a variety of blends and combinations with other additives, including antioxidants, processing stabilizers, and light stabilizers. Higher load levels of Benetex OB are required if it is used in combination with a UV absorber. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Please contact Mayzo for specific recommendations.
