Speedblock UV-6

Technical Datasheet | Supplied by Lambson
Speedblock UV-6 by Lambson is 2-Hydroxy-4-n-octoxybenzophenone. Acts as a UV absorber. It protects by preferentially absorbing harmful ultraviolet radiation and dissipating it as thermal energy. High concentrations are generally required along with sufficient thickness of the polymer for effective absorption to retard photo degradation. Displays low odor & volatility during high temperature processing. Speedblock UV-6 is compatible with unsaturated polyesters, polystyrenes, polymethylacrylates. Recommended dosage is 0.1-0.5% depending on the substrate, processing conditions and applications. It has a shelf life of 2 years.

Hansen Solubility Parameters

[18.6, 3.9, 9.2]
[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 Speedblock UV-6. A practical determination of these HSP values would provide higher certainty. Learn More.
