COMPOSITION FOR ANTIBURN-ON COATING Russian patent published in 1997 - IPC

Abstract RU 2071967 C1

FIELD: antifriction compositions. SUBSTANCE: composition has, %: 50-65%-th aqueous suspension of polytetrafluoroethylene 53.8-73.5; mica modified with an aqueous solution of polyvinylpyrrolidone in the presence of hydroxyethylated alkylphenol at ratio (20:1:8:30.2), respectively, 3.3-8.2; pigment 4.02-5.9; ethylcellosolve 0.6-1.0; xylene 2.0-2.8; hydroxyethylated alkylphenol 2.5-5.7, and water - the rest. Coating properties: thermic resistance to the boiling vegetable oil action is 850-1000 h, resistance to thermoimpacts at temperature gradient from 225 to 10 C is 35-45 cycles, antiburn-on property - easily washing off with water. EFFECT: enhanced quality of composition. 3 tbl
