COMPOSITION FOR MANUFACTURE OF COATS BY ANODE ELECTRIC DEPOSITION Russian patent published in 1998 - IPC

FIELD: automobile and chemical industries, machine and instrument making, electrical and radio engineering. SUBSTANCE: invention refers to deposition of coats by water-solved varnish-and-paint pigmented compositions. Proposed composition includes film former - cis-polybutadiene rubber (varnish KКЧ-0125), red ferric oxide pigment, neutralizer - 25-% aqueous solution of ammonia and water with following ratio of components, mas.%: cis-polybutadiene rubber, 16.30- 17.66; red ferric oxide pigment, 1.25-2.03; 25-% aqueous solution of ammonia, 1.10- 1.19; water, the balance. Use of the composition makes it possible to manufacture coats with high anticorrosion properties such as resistance to salt in 3-% solution of NiCl amounts to 26-45 days, water resistance not less than 1200-1300 h, gasoline and oil resistance not less than 60-72 h. EFFECT: high anticorrosion characteristics. 2 tbl
