    摘要: Anticorrosive coating compositions comprise a binding polymer and an amorphous aluminum phosphate corrosion inhibiting pigment. The composition comprises from about 1 to 25 percent by weight amorphous aluminum phosphate. The amorphous aluminum phosphate has a water adsorption potential of up to about 25 percent by weight water. The composition provides a controlled phosphate delivery of from about 50 to 500 ppm, and preferably of from about 100 to 200 ppm. The composition has a total solubles content of less than about 1,500 ppm. The amorphous aluminum phosphate is preferably substantially free of alkali metals. The amorphous aluminum phosphate is made by combining aluminum hydroxide with phosphoric acid and sodium aluminate. The amorphous aluminum phosphate is treated to reduce the level of unwanted solubles, and the treated amorphous aluminum phosphate is dried at less than about 300°C. The composition is used as a primer coat, a mid-coat, and/or a top-coat coating.

    摘要: An aluminum phosphate composition comprising aluminum phosphate, aluminum polyphosphate, aluminum metaphosphate, or a mixture thereof. The composisition may be characterized by, when in powder form, having particles wherein some of the particles have at least one or more voids per particle. In addition, the composition is characterized by exhibiting two endothermic peaks in Differential Scanning Calorimetry between about 90 degrees to about 250 degrees Celsius. The composition is also characterized by, when in powder form, having a dispersibility of at least 0.025 grams per 1.0 gram of water. The composition is made by a process comprising contacting phosphoric acid with aluminum sulfate and an alkaline solution to produce an aluminum phosphate based product; and optionally calcining the aluminum phosphate, polyphosphate or metaphosphate based product at an elevated temperature. The composition is useful in paints and as a substitute for titanium dioxide.
