<p>A thermoplastic olefin containing a light stabilizer package is disclosed. The light stabilizer package comprises a monomeric HALS having a pKa of no greater than 7, an ultraviolet light absorber and a polymeric HALS having a pKa of less than 7. The light stabilizer package is blended with the thermoplastic olefin to form a moldable light stable composition. Articles made of the moldable light stable composition may have an exterior surface that is at least partially coated with acid curative paint systems without interference from the light stabilizer package.</p> |
