Low/No-VOC and Nonchromate Coating System for Support Equipment
Project Number: J-99-OC-014

Current primer and topcoat formulations used for DoD and NASA aerospace vehicle support equipment contain hexavalent chromium, lead, VOCs, and HAPs such as MEK, toluene, and xylene. To eliminate or reduce the ESOH issues associated with these HazMats, the JG-PP Low/No-VOC and Nonchromate Coating System for Support Equipment project is demonstrating that alternative technologies meet the performance standards required by the DoD and NASA for their support equipment and that those technologies can be implemented as a coating system. The stakeholders agreed on eleven advanced film technology, high-solids coating, metal wire arc spraying, powder coating, and waterborne coating primer/topcoat systems for testing. Testing of the potential alternatives was completed in June 2001. Based on the test results the stakeholders selected the following five potential alternative coating systems for field demonstrations:

• Coating System Eight, Powder Coating (Morton 13-7004 Corvel Zinc Rich Primer with Morton 30-1007 Corvel Clean White U 1578 topcoat)
• Coating System Nine, Powder Coating (DuPont ELH503S5 Gray Morning primer with DuPont PFW510S9 Sky White topcoat)
• Coating System Ten, Waterborne (Deft 44-GY-16 Zinc Rich Primer/Deft 44-W-7 Intermediate Primer with Defthane Zero VOC topcoat)
• Coating System Eleven, Waterborne (Aqua-Poxy 912 primer with Defthane Zero VOC topcoat)
• Coating System Six, High Solids (Dimecote 9HS Zinc Rich Primer with Ameron PSX 700 Siloxane Self-priming topcoat) - NASA, only.

There are four field demonstration sites that include two Navy facilities, NAS Brunswick and Solomons, and two Air Force facilities, Cape Canaveral and Patrick AFB.

For the JG-PP Low/No VOC and Nonchromate Coating System for Support Equipment project, the participants defined "support equipment" as mobile and fixed, combat- and aviation-related ground equipment in powered and non-powered categories. Powered support equipment includes, but is not limited to, avionics, portable/mobile generators, air compressors, hydraulic service units, air conditioners, ground heaters, light carts, gas turbine service equipment, universal maintenance stands, and self-propelled bomblifts. Non-powered support equipment includes, but is not limited to, maintenance stands, towbars, oxygen/nitrogen service carts, and jacks.
