Zusammenfassung:	PCT No. PCT/EP96/04208 Sec. 371 Date Mar. 6, 1998 Sec. 102(e) Date Mar. 6, 1998 PCT Filed Sep. 26, 1996 PCT Pub. No. WO97/12005 PCT Pub. Date Apr. 3, 1997The invention relates to the use of precrosslinked silicone elastomer particles with an organopolymer shell as the formulation constituent in powder coating material compositions based on thermoplastic or thermosetting binding agents, the silicone elastomer particles containing (a) 5 to 95% by weight, in relation the total weight of the copolymerisate, of a nucleus polymer of the general formula (RwSiO2/2)x.(RSiO3/2)y.(SiO4/2)z with x=5 to 99.5 mol %, y=0.5 to 95 mol %, z=0 to 30 mol %, and (b) 5 to 95% by weight, in relation to the total weight of the copolymer, of a shell made of an organopolymer of ethylenically mono or multi-unsaturated monomers, R standing for identical or different monovalent C1-C6 alkyl or alkenyl residues or substituted hydrocarbon residues.
