摘要： This invention relates to aqueous epoxy resin-containing compositions and to such compositions which are particularly useful for depositing coatings on metalic 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, and polytetrafluoroethylene as a lubricant to aid metal stamping operations, and a soluble colorant.

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.

摘要： A process for pretreating a substrate is disclosed. The process includes applying a composition comprising a fluorescing agent to treat an area of the substrate. The treated substrate area is then rinsed to remove excess composition. The rinsed substrate area is exposed to an energy source whereby the fluorescing agent exhibits a color upon exposure to the energy source to detect excess composition remaining on the rinsed substrate.

摘要： A mar resistant, weldable zinc-coated metal substrate capable of sustaining the life of a copper-tipped electrode used in welding the substrate through a minimum of 2000 welds is achieved by applying a weldable primer coating composition to the metal, heating the primer composition to provide the desired dry coating, applying a protective coating composition over the primer coating in an amount sufficient to provide from about 50 to about 400 mg/ft.sup.2 of a dry film, and heating the protective coating composition to produce the dry film. Without the resin-based protective coating, the weldable primer is easily marred. The resin-based protective coating, which is from about 0.06 mil to about 0.13 mil thick, improves the mar resistance of the primer and enhances the corrosion resistance of the zinc-coated steel without interfering with the weldability of the primer. The primer contains from about 30 to about 60% of ferrophosphorus and from 0 to about 30% by weight zinc powder. When zinc is present, the ratio of ferrophosphorus to zinc is from about 9:1 to about 1:1 by weight.
