PROTECTIVE ORGANIC COATINGS FOR GENERAL EXTERNAL AIRCRAFT APPLICATION.

Abstract

The present test and evaluation program is centered around the finding of coating systems which retain a substantial degree of flexibility on aging and weathering. Silicone-acrylic coatings appear superior to the standard acrylic coatings as regards resistance to discoloration on heating to 400 F for 24 hours or exposure to UV radiation -- also, they show an improved retention of flexibility. There were a number of other coating types which, while discoloring when subjected to heat aging at 400 F, showed up better than the above acrylic or silicone-acrylic coatings as regards their retention of flexibility after exposure to UV radiation or a temperature of 400 F. Included in this category were certain silicone-epoxies, moisture curing urethanes, high molecular weight urethanes, acrylic/urethanes, vinyl/urethanes, polysulfones, silicone modified moisture curing urethanes, silicone modified high molecular weight urethanes, silicone modified acrylic/urethanes and silicone modified vinyl/urethanes.
