Abstract

A zinc phosphating composition containing organoperoxide along with zinc ions and phosphate ions forms finely crystalline, dense, and thin conversion coatings on metal surfaces that are normally zinc phosphate conversion coated, even at coating temperatures below 50 degree C and without any "conditioning" of the surface before conversion coating by contact of the surface to be conversion coated with a conventional colloidal suspension of titanium salts.
