Tinuvin 765 is a liquid hindered amine light stabilizer which is widely used to improve the weatherability of a variety of polymers.

Use levels for Tinuvin 765 range between 0.1 % and 1.0%, depending on the substrate and performance requirements. Synergistic performance may be obtained when this product is used with an ultraviolet light absorber.

For optimum effectiveness, adequate base stabilization (e. g. antioxidants/ processing stabilizers) of the polymer is necessary to prevent thermal oxidation. Sulfur containing stabilizers such as thioethers have sometimes been found to have a negative effect on the performance of Tinuvin 765. Such influences should be evaluated in specific customer testing. Tinuvin 765 may crystallize during storage below 0 °C, however the product can be easily liquified by slight warming.

Applications

Tinuvin 765 is a highly effective liquid stabilizer used for a wide range of polymers and applications including polyurethanes, sealants, adhesives, elastomers, unsaturated polyesters, acrylics, vinyl polymers (PVB, PVC), styrene homo- and copolymers, polyolefins, liquid color concentrates, and other organic substrates.
