CTMA Project #: 110455
Problem: Current DOD depot maintenance de-painting operations use chemical strippers and plastic media blasting (PMB) that generate large amounts of hazardous waste creating environmental issues. This exposure poses significant employee health concerns. In addition, Air Force landing gear overhaul operations annually consume 10,000 gal. of paint stripper and 36,000 lbs. of PMP.
Solution/Approach: The primary objective of this project is to formulate a UADP solution with broader alloy (e.g., steel) compatibility, while maintaining effectiveness in removing paint. One such method of improving alloy compatibility is reformulating the solution to a pH that is closer to neutrality. A more broadly compatible composition will eliminate the need for removing steel fasteners from aluminum aircraft components such as wheels and gearboxes prior to depainting.
Benefit: Project tasks will result in reduced cost of hazardous waste disposal and pretreatment requirements, significant reduction in employee personal protective equipment, improved occupational health conditions for operators, and elimination of toxic chemicals and plastic media from Department of Defense (DOD) de-paint operations.
