Abstract

Durable elastomeric polyurea coatings can be applied to metal surfaces subjected to impacts and environmental corrosion. Corrosion resistance of the coatings, especially on magnesium alloy surfaces, is improved by incorporation of particulate inhibitor additives in the liquid polyurea precursor coating material. Examples of inhibitors include potassium dichromate, sodium dichromate, potassium permanganate, vanadium pentoxide, phosphorus anhydride, cerium oxide, lanthanum oxide, calcium oxide and sodium oxide.
