PROTECTIVE POLYMERIC COMPOSITION Russian patent published in 1999 - IPC

Abstract RU 2141496 C1

FIELD: chemical industry. SUBSTANCE: protective polymeric composition for antifriction coatings comprises fluorine-containing binder and organic solvent. Binder includes nitrogen- containing perfluoropolyoxaalkylene carboxylic or sulfonic acid derivatives of general formula: RFR1F

XQ wherein RFR1F
XQ are as defined in claim 1. Organic solvent is fluorohydrocarbon or fluorochlorohydrocarbon solvent or mixtures thereof with ethyl, methyl or isopropyl alcohol at alcohol content of up to 80 wt % in mixture and further comprises surfactant dispressant ratios of components being as follows, wt %: nitrogen-containing perfluoropolyoxaalkylenecarboxylic or sulfonic acid derivatives, 0.1-10.9; dispersant, 0.1-4.0; and the organic solvent balance. EFFECT: simplified composition and coatings having higher wear resistance and low friction coefficient. 4 cl, 12 ex, 3 tbl
