PPG Aerospace-PRC-DeSoto has qualified its new-generation high-solids low-VOC exterior epoxy aerospace primer at Boeing that exhibits superior adhesion, flexibility and rain-erosion resistance, according to PPG coatings officials.
Desoprime HS CA7700 epoxy primer is qualified to Boeing specification BMS 10-72 Type VIII and will soon be on all new Boeing aircraft painted with Desothane HS topcoat.
Already qualified by Bombardier Aerospace and Embraer, Desoprime HS CA7700 series primers have passed the whirling arm test for rain-erosion resistance and filiform salt fog test for corrosion resistance. There was no loss of adhesion or cracking at 40 inch-pounds with impact testing.
With a lower percentage of volatile organic compounds, its environmentally friendly formula meets the emission requirements of North and South America.
