Dispersions, Resins and Additives

Tinuvin® 

Light stabilizers and UV absorbers that deliver excellent protection from degradation.

Tinuvin performance additives are designed to protect coatings from UV degradation and extend service life. Our portfolio includes two complementary light stabilization techniques: Ultraviolet Absorbers (UVA) and Hindered Amine Light Stabilizers (HALS).

UV absorbers protect coatings by filtering harmful ultraviolet radiation, helping prevent color fading, resin yellowing, and substrate degradation. HALS technology scavenges free radicals generated by UV exposure, preserving gloss and reducing surface defects such as cracking and chalking. 

The Tinuvin 5000 series and other Tinuvin blends combine UVA and HALS technologies to deliver enhanced protection, superior color and gloss retention, and long-term durability. These easy-to-handle additives are compatible with most solvent-based systems and meet the demanding performance requirements of automotive, industrial, architectural, wood, plastic, and metal coating applications. 

By combining UV filtering and free-radical scavenging mechanisms, Tinuvin light stabilizer blends provide comprehensive protection against weathering and surface degradation, helping coatings maintain their apperance and performance over time.
