COMPOSITION FOR COATINGS Russian patent published in 2001 - IPC

FIELD: polymeric powder compositions for applying coatings onto metal surfaces for anticorrosion and tribotechnical purposes. SUBSTANCE: described is composition comprising thermoplastic polymer and dielectric filler which carries electric polarization charge. Filler includes ultradispersed particles of solid α-Al₂O₃ solution and AlN in β-Si₃N₄ (beta-Kapron) prepared by method of plasmochemical synthesis, ratios of components being as follows, wt. %: thermoplastic polymer, 93-99; and beta-Kapron, 1-7. The claimed composition intended for application in machine-building products. EFFECT: improved anticorrosion and tribotechnical characteristics of the composition. 2 tbl
