2-(2’-Hydroxy-3’, 5’-di-t-butylphenyl)-5-chlorobenzotriazole. It is a highly effective light stabilizer. Due to its red-shifted UV absorption, it is particularly suited for use in the stabilization of polymers that are especially sensitive to long-wavelength UV radiation. It is compatible with acrylic polymers, polycarbonate, polyesters, styrene homo- and copolymers, unsaturated polyesters, polyurethanes, polyphenylene sulfide, polyvinylchloride, polyolefins, polyvinyl butyral and elastomers. Used in certain applications where very low transmission of long-wavelength UV radiation is required e.g. optical lenses.

Hansen Solubility Parameters

[18.5, 4.2, 4.3]
[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 5327. A practical determination of these HSP values would provide higher certainty.
