METHOD OF PREPARING BISMUTH SALT-CONTAINING COMPOSITIONS AND UTILIZATION THEREOF IN CATHODICALLY PRECIPITATED LACQUERS FOR ELECTRICAL IMMERSION LACQUERING Russian patent published in 1999 - IPC

Abstract RU 2137866 C1

FIELD: lacquer coatings. SUBSTANCE: bismuth oxide is specifically brought into interaction with lactic acid and resulting bismuthyl oxide-bismuth oxide mixture is dispersed in lacquer binder. These compositions are used as catalytic components in cathodically precipitated lacquers. Lacquers prepared in such way possess excellent capability of being applied as coatings and films. EFFECT: avoided utilization of lead and tin as catalysts. 4 cl, 2 tbl, 4 ex
