| abstract | 1504846 Chromating metal substrates DIAMOND SHAMROCK CORP 19 March 1976 [20 March 1975] 11213/76 Heading B2E [Also in Division C7] Chromate coatings are formed on substrates e.g. steel, by (a) coating with a heat curable liquid composition containing Cr<SP>6+</SP> and a reducing agent and heating to reduce the Cr<SP>6+</SP> (b) applying a second coating containing Cr<SP>6+</SP> and a reducing agent which may be the same as (a) and then heating at a higher temperature so that the reduced Cr reverts to Cr<SP>6+</SP>. The first heating may be at <550‹F for < 10 mins. e.g. 450-500‹F for # 25 mins. and the second coating may be heated at > 550‹F for > 10 mins. e.g. 600-700‹F for for 10-20 mins. The coatings (a) and (b) may contain dipropylene glycol, Zn flake, water, chromic acid and hydroxyethyl cellulose and a paint, primer, enamel, varnish or lacquer may be applied. |
