Benzotriazole UV absorbers have exceptionally strong and broad-range UV absorption properties throughout the UV spectrum. Especially designed for polymers and coatings. Due to its extended UV absorption capability, this product provides excellent protection for plastics. However, also for top coats and various light sensitive substrates. It is highly recommended for thermoset plastics, organic substrates and coatings that function as weathering. This product may also be used in conjunction with other light stabilizers of HALS class. For instance, to give plastics, coatings and paints superior protection against gloss reduction, cracking, color change, blistering, chalking and delamination. To sum up, they have excellent performance in the spectrum range of 350nm - 400nm.
