    摘要: Chromate free treatments and compositions for applying a conversion or passivation coating to metal surfaces. Preferred compositions comprise a film forming latex polymer, fluoacid, phosphoric acid, and a polyoxyethylene/oxypropylene block copolymer. The requisite metal surfaces are contacted by the compositions and dried. Rinsing is optional.
