TINUVIN® light stabilizers and UV absorbers
TINUVIN performance additives for UV protection and durability are designed to protect and extend the lifetime of coatings. Our portfolio contains two types of light stabilizers: Ultraviolet Light Absorbers (UVA) and Hindered-Amine Light Stabilizers (HALS). Based on the nature of the light absorbing unit, several types of UVA are commercially available. Benzotriazoles offer the broadest spectral coverage.
HALS trap free radicals maintain surface properties such as gloss and prevent cracking and chalking of paints. When combined, UVA and HALS provide synergistic effects and offer simplicity of formulation.
