초록 ▼

This invention relates to aqueous epoxy resin-containing compositions and to such compositions which are particularly useful for depositing coatings on metallic substrates in order to protect substrates against corrosion. The aqueous compositions generally comprise (A) an organic resin component consisting essentially of at least one water-dispersible or emulsifiable epoxy resin or a mixture of resins containing more than 50% by weight of at least one water-dispersible or emulsifiable epoxy resin, (B) chromium trioxide, and (C) water, said composition further characterized as being substantially free of strontium chromate. The aqueous compositions may also contain other ingredients including zinc and/or ferro alloys. These aqueous compositions are useful as pretreatment coatings on metal surfaces, and in particular, on steel and on galvanized and aluminized metal substrates. This pretreatment coating can then be coated with weldable or non-weldable primer coatings followed by the application of decorative topcoats such as appliance topcoats or automotive topcoats. The invention also relates to metal substrates which have been coated with the pretreatment coating and, optionally, the weldable or non-weldable primer coatings.
