Abstract
Anticorrosive coating compositions as disclosed comprise a binding polymer and an aluminum phosphate corrosion inhibiting pigment dispersed therein. The coating composition comprises up to 25 percent by weight aluminum phosphate. The binding polymer can include solvent-borne polymers, water-borne polymers, solventless polymers, and combinations thereof. The aluminum phosphate is made by sol gel process of combining an aluminum salt with phosphoric acid and a base material. Aluminum phosphate colloidal particles are nanometer sized, and aggregate to form substantially spherical particles. The coating composition provides a controlled delivery of phosphate anions of 100 to 1,500 ppm, depending on post-formation treatment of the aluminum phosphate, and has a total solubles content of less than 1500 ppm, The amorphous aluminum phosphate is free of alkali metals and alkaline earth metals, and has a water adsorption potential of up to about 25 percent by weight water when present in a cured film.
