LOWILITE™ 28 benzotriazole-type UV light absorber provides strong protection from degradation for a variety of polymers when exposed to UV in the range of 290–400 nm.
LOWILITE™ 28 is a strong benzotriazole UV light absorber that prevents the yellowing and degradation of various polymers, including two-part epoxies and urethanes. LOWILITE™ 28 UV stabilizer absorbs harmful UV radiation, dissipates the radiation as heat, and protects the polymer additives behind the entire product.
