Abstract:

Two corrosion preventive organic coatings have been developed for use on aluminum and specifically for application on Navy aircraft. They provide two alternatives for improving aircraft paint systems. The first coating can be applied directly to an aluminum substrate and perform as a self-priming topcoat. It consists of a two component, aliphatic polyurethane binder with titanium dioxide, zince molybdate, zince phosphate, an organo-zinc salt, and titanium dioxide vesiculated bead pigments. This primertopcoat meets or exceeds all of the critical performance requirements of the current Navy aircraft paint system. Mil-P-23377 epoxy primer and Mil-C-83286 polyurethane topcoat. It exhibits good adhesion, corrosion inhibition, flexibility, chemical and weather resistance. The primertopcoat has been formulated in lusterless gray colors common on Navy tactical aircraft. The volatile organic content VOC of the primertopcoat prior to thinning is 395 grams of organic solvent per liter of paint. The VOC after thinning with 1.1.1 trichloroethane, which is currently an exempt solvent, to a viscosity compatible with conventional air spray, is 295 grams per liter.
