BLS® 1328

Technical Datasheet | Supplied by Mayzo
HSP Distance with TPPi: 4.0
UV absorber highly recommended for protective coatings. Does not cause yellowing. Provides excellent protection in a variety of automotive coating substrates. Has excellent solubility in urethane solvents, is non-reactive and has no effect on the cured properties of the coating while protecting against loss of gloss. Soluble in a wide range of organic solvents, has a low volatility during high processing temperatures, has a good extraction resistance.

Hansen Solubility Parameters

[18.2, 3.9, 3.7]
?
[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 BLS® 1328. A practical determination of these HSP values would provide higher certainty. Learn More.
