PCT No. PCT/SE93/00482 Sec. 371 Date Dec. 1, 1994 Sec. 102(e) Date Dec. 1, 1994 PCT Filed Jun. 1, 1993 PCT Pub. No. WO93/24581 PCT Pub. Date Dec. 9, 1993.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. |
