Abstract
A corrosion resistant coating to protect metallic and polymeric composite surfaces from corrosion and water promoted deterioration that is environmentally safe and non-toxic and is applied in one coat without the use of a primer is provided. The coating comprises a tough, flexible polyurethane binder and a corrosion inhibiting pigment selected from the group consisting of zinc hydroxy phosphite, zinc phosphate, calcium ion-exchanged silica, calcium strontium zinc phosphosilicate. The coating is effective in protecting both aluminum and steel surfaces against corrosion in salt spray environments and in protecting polymeric composite materials such as ablative coatings used in aerospace against deterioration after exposure to water.
