Abstract
Self-healing coatings are formed by first phosphating or nitriding ferrous parts, then coating with an emulsion of e.g. polysiloxane, oil, sorbitan derivative and sodium sulfonate, butyl cellosolve, oleic acid. Preferred phosphating is to a thickness of 2,000-3,000 mg Zn phosphate/square foot. This coating passes 240-plus hours in 5% salt spray (ASTM B-117) and resists wash off with car wash soap.
