Speedblock UV-P

Technical Datasheet | Supplied by Lambson (Sartomer)
Speedblock UV-P by Lambson (Sartomer) is 2-(2H-benzotriazol-2-yl)-p-cresol. Acts as a ultraviolet light absorber. can be used alone or with other additives such as hindered light stabilisers and antioxidants where more often than not a synergistic performance can be observed. Features a very strong absorption band between 300 – 400 nm and also exhibits a high degree of photostability over long periods of light exposure. Speedblock UV-P is compatible with styrene homo- and co-polymers, polyesters, cellulose esters, epoxy materials, elastomers, acrylic resins, polyurethanes, polyvinylchloride, polyacetals. Recommended dosage is 0.1-0.5% depending on application. It has a shelf life of 2 years.
