METHOD OF PREPARING ELECTROINSULATING VARNISH Russian patent published in 1997 - IPC

Abstract RU 2071613 C1

FIELD: varnish and dye industry. SUBSTANCE: varnish is prepared by polycondensation of mixture of terephthalic and isophthalic acids or their dialkyl esters and polyatomic alcohols in an organic solvent medium with subsequently introducing into obtained resin a polyorganosiloxane and tetraalkoxytitanate in amounts 0.16-0.70 and 0.64-0.70%, respectively, based on varnish weight. EFFECT: simplified process, improved environmental condition, and reduced friction coefficient of insulator. 2 tbl
