PPG Industries aerospace coatings group has introduced an electrocoat-application primer designed for global airframe manufacturers and subcontractors to coat parts for commercial, military and general-aviation aircraft. PPG Aerospace’s Aerocron e-coat primer provides better corrosion protection than conventional spray primer because electrocoating enhances part coverage, the company says. It also is said to provide nearly 100-percent product utilization, reduce primer weight for enhanced aircraft fuel economy and eliminate worker overspray exposure.
Primer typically is sprayed onto metal aircraft structures for corrosion resistance, but in the electrocoating or electrodeposition process, the metal parts are dipped into an electrically charged tank of primer. Aerocron is designed to coat parts uniformly, even in the recessed areas of complex-shaped parts, and at reduced weight, resulting in long-term aircraft operation savings.
For aircraft manufacturers and subcontractors, the electrocoat process can be fully automated and offers increased material utilization. For their customers, it provides better corrosion protection and lighter weight.
