Additive solutions for automotive exterior parts -
outstanding light protection and high quality appearance

A door handle is the first contact with a car, therefore it must have an extremely smooth surface for an agreeable grip. Body panels, bumpers and exterior trims done in bold, radiant colors should not fade over time. And headlamp lenses, screens or panoramic roofs using polycarbonate (PC) or polyacrylate (PMMA) compounds require to stay transparent, keep their initial color and mechanical properties, for both safety and aesthetic reasons. 

Clariant has developed cost-efficient solutions, based on high performance light stabilizers, that provide outstanding UV protection and mechanical resistance to many parts of a car's exterior, like body panels made from polypropylene compounds. These specialty light stabilizers make plastic materials strong and stable and ensure that the vibrant, intense color of a new car does not turn into a faint memory over time. Transparent elements are protected from unattractive yellowing, car parts retain excellent surface appearance even under severe weather conditions.


  • AddWorks® ATR 945 mp
    AddWorks ATR 945 mp is a low molecular weight hindered amine light stabilizer particularly designed for light stabilization of non-polar polymers (e.g. polyolefins). This specific solution offers an optimal stabilization to PP compounds.
  • Hostavin® B-CAP™
    Hostavin B-CAP is a UV absorber with pronounced absorptivity in the high energy (low wavelength) range of the UV spectrum.
  • Hostavin® N 30 pills
    Hostavin N 30 pills is an oligomeric hindered amine light stabilizer (HALS), designed for light stabilization of plastic materials. This HALS is characterized by its broad compatibility and excellent resistance to migration.
