Abstract:
A partially painted article having an exterior surface and comprising a molded light stabilized polymeric composition that does not interfere with acid curative coating systems, said polymeric composition comprising(a) a thermoplastic polyolefin;(b) a monomeric hindered amine light stabilizer having a basicity or pKa of no greater than 7, said monomeric light stabilizer selected from the group consisting of polyalkyl piperidinyl acetamide compounds, polyalkyl piperidinyl ester compounds and triazaspiro-alkane-dione compounds;(c) a polymeric hindered amine light stabilizer of a polyalkyl piperidin-succinic acid copolymer having a basicity or pKa of no greater than 7; and(d) an ultraviolet light absorbing agent of a benzophenone compound, wherein each of the monomeric hindered amine light stabilizer, the ultraviolet light absorbing agent and the polymeric hindered amine light stabilizer are present in an amount effective to provide a stable substrate for an acid catalyst activated single component paint system, and wherein at least a portion of said surface is coated with said acid catalyst activated single component paint system.
