SpeedBlock UV-6 by Lambson (Sartomer) is a 2-Hydroxy-4-n-octoxybenzophenone. Acts as a benzophenone type UV absorber. It has low odor & volatility during high temperature processing. 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. This pale yellow powder is readily compatible with a range of polymers such as alkyds, epoxy resin, unsaturated polyesters, polystyrenes and polymethacrylates. SpeedBlock UV-6 is suitable for coatings and varnishes. Typical addition level ranges from 0.1-0.5% depending on the substrate, processing conditions and applications.
