This invention relates to a corrosion-resistant coating capable of being lied to various substrates, e.g., particularly metal and plastic surfaces, as a single coat characterized as having a high-gloss, good adhesion and a high degree of flexibility. The corrosion inhibiting composition comprises an acrylic resin containing an effective amount of a corrosion-inhibiting pigment system consisting essentially of critical amounts of at least one zinc phosphate, zinc molybdate and at least one zinc salt of a benzoic acid.

Corrosion-resistant alkyd coatings

This invention relates to a corrosion-resistant coating capable of being lied to various substrates, e.g., particularly metal and plastic surfaces, as a single coat characterized as having a high-gloss, good adhesion and a high degree of flexibility. The corrosion inhibiting composition comprises an epoxide resin containing an effective amount of a corrosion-inhibiting pigment system consisting essentially of critical amounts of at least one zinc phosphate, zinc molybdate and at least one zinc salt of a benzoic acid.

Epoxy corrosion-resistant coating

A high-gloss, corrosion-resistant coating which can be applied directly to surface comprising about 30 to 82 percent by weight of a polymeric binder and 18 to 70 percent by weight of a pigment system consisting essentially of zinc molybdate, zinc salt of benzoic acids, and zinc phosphate in specific ratio's. The coating exhibits good adhesion, flexibility, chemical- and weather-resistance.

High gloss corrosion-resistant coatings

A coating for metallic or polymeric composite substrates is disclosed which erforms both as a primer and as a topcoat. It comprises a two component aliphatic polyurethane binder, with titanium dioxide, zinc molybdate, zinc phosphate, an organo-zinc salt, and titanium dioxide vesiculated bead pigments in controlled amounts. The coating exhibits good adhesion, corrosion inhibition, flexibility, chemical and weather resistance, and opacity.
