摘要: A method and composition for sealing of a conversion coating is disclosed. The method includes contacting a metal substrate, to which has been applied a conversion coating, with an aqueous solution including a heterocyclic alcohol. The preferred heterocyclic alcohol is tetrahydro-2-furanmethanol. The sealer may dry in place or be followed by a water rinse.

摘要: A chromate and phosphate free composition and method for forming a dried in place conversion coating for aluminum and aluminum alloys. The method entails the application of the composition to aluminum or aluminum alloys and allowing the composition to dry in place. The composition is an acidic aqueous solution preferably containing more than 8 grams per liter dihydrohexafluozirconic acid, more than 10 grams per liter polyacrylic acid and more than 0.17 grams per liter hydrofluoric acid in a ratio of 1:0.84:0.014. Up to about 0.6 gram per liter dihydrohexafluotitanic acid is added to facilitate analytical testing in aqueous systems. The solution forms a dried in place conversion coating having a weight of from 6 to 25 milligrams per square foot in treatment (contact and drying) times as short as 2 seconds.
