<p>A coating composition suitable as an undercoating for cars contains vinyl-chloride-polymer-based plastisol and expandable thermoplastic microspheres. The expandable thermoplastic microspheres have a substantially halogen-free polymer shell which comprises a copolymer of halogen-free monomers and, in an amount of at least about 80 % by weight, nitrile-containing monomers. Preferably, the polymer shell of the thermoplastic microspheres contains from about 85 % by weight to about 97 % by weight of nitrile-containing monomer. A method for spray-coating a surface with the coating composition by airless spraying is also disclosed.</p> |
