Abstract

Two corrosion preventive organic coatings have been developed for use on aluminium and specifically for application on Navy aircraft. The first coating can be applied directly to an aluminium substrate and perform as a self‐priming topcoat. It consists of a two component, aliphatic polyurethane binder with titanium dioxide, zinc molybdate, zinc phosphate, an organo‐zinc salt, and titanium dioxide vesiculated bead pigments. The second coating is a flexible primer which was developed using the above polyurethane binder. It contains strontium chromate zinc chromate, barium chromate, and zinc molybdate corrosion inhibiting pigments. Aluminium specimens coated with the NADC flexible primer remained in 5% salt spray for one year without any corrosion of the aluminium or damage to the coating. BH 36pp.
