2-(2H-benzotriazol-2-yl)-p-cresol. Acts as a UV absorber. It features a strong absorption of ultraviolet radiation in the 300-400 nm region. Has a high degree of photostability over long periods of light exposure. Used for variety of polymers including styrene homo-and copolymers, polyvinyl chloride, engineering plastics such as polyesters and acrylic as well as other halogen containing polymers and copolymers (e.g. vinylidenes). Can also be used in acetals, elastomers, cellulose esters, polycarbonate blends, polyurethanes and epoxy materials. Recommended to be used at dosage of 0.1-0.5%.

Hansen Solubility Parameters

[20.4, 7.7, 7.8]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with OMNISTAB UV P. A practical determination of these HSP values would provide higher certainty. Learn More.
