Superiority

UV-P

Drometrizole provides ultraviolet protection in a wide variety of polymers including styrene homoand copolymers, engineering plastics such as polyesters and acrylic resins, polyvinyl chloride, and other halogen containing polymers and copolymers (e.g. vinylidenes), acetals and cellulose esters. Elastomers, adhesives, polycarbonate blends, polyurethanes, and some cellulose esters and epoxy materials also benefit from the use of Drometrizole.

2-(2-Hydroxy-5-methylphenyl)benzotriazole is an intermediate reactant in the synthesis of UV light absorbers for polyester fibers. It is used in microstereophotolithography of miniaturized actuators, in PVS and wood / PVC composites as a stabilizer and in acrylonitrile-butadiene-styrene as a UV absorber.

Details

The use levels of Drometrizole range between 0.10% and 0.50%, depending on substrate and performance requirements of the final application. Drometrizole can be used alone or in a variety of blends and combinations with stabilizers where often a synergistic performance is observed. Drometrizole may react with various heavy metal ions to form salts or complexes. For example, if Drometrizole comes into contact with iron or cobalt ions, colored complexes are formed. Reducing and oxidizing agents used in polymerization and curing processes have no effect on the stability of Drometrizole.

Particularly effective in styrene polymers, PVC, unsaturated polyesters, polyurethanes, acrylic polymers, and polycarbonates.

UV P can be used alone or in a variety of blends and combinations with antioxidants or UV absorbers where often a synergistic performance is observed.

Tinuvin P has FDA approval for use in a wide variety of food contact applications.

The use levels range between 0.10% and 1.0%, depending on substrate and performance requirements of the final application.
