Tinuvin XT 850 is a high performance light stabilizer system, which imparts outstanding weatherability to polyolefins. The main advantage of Tinuvin XT 850 over other stabilization systems is that it is not interacting with acid-cured 1-component automotive coatings and other acidic components. Tinuvin XT 850 also contributes significantly to the long-term thermal stability of polyolefins.

Applications

Tinuvin XT 850 is a highly effective light stabilizer for polyolefins and other plastics. Its use is especially recommended for the stabilization of blends of polypropylene with elastomers (TPO) for paintable automotive applications. Other applications include molded-in-color TPO, TPE, TPV, and polypropylene, polyethylene, polyvinylchloride, thermoplastic polyester elastomers, and polyurethanes.

Features & Benefits

Tinuvin XT 850 features powerful light and long-term thermal stabilization performance in polyolefin substrates. It is non-interacting with acid-cured 1-component automotive coatings and acidic formulation components. Its excellent compatibility with polyolefins provides additional benefits such as good resistance to fogging for automotive interior applications and reduced mold deposit formation. It protects polymers from UV radiation, helping to preserve the original appearance and physical integrity during weathering.
