Potential Alternatives Report
As part of the RTIS , Dallas, Texas, JG-PP project, VOCs in coatings were identified as HazMats of concern, and targeted for elimination or reduction. Low gloss, low-temperature cure, chemical-agent-resistant powder coatings were initially identified as the preferred alternative to high-VOC coatings, but other alternatives were also investigated to identify new technologies that might prove acceptable. This PAR documents the analysis of identified alternatives and the rationale behind the selection of alternatives for validation testing.
Nine alternative materials or processes having the potential to replace primers and topcoats containing the VOCs methyl ethyl ketone, toluene, and xylene were identified through literature searches and direct vendor queries. These identified alternatives were high-solids, 100% solids, waterborne, alternative solvent, ion-vapor deposited, powder, radiation-curable, self-priming topcoat, and supercritical CO2 sprayed coatings. Of these nine materials, MIL SPECs were available for high-solids (MIL-C-85285 and MIL-C-46168, Type IV) and waterborne coatings (MIL-P-85582). These MIL SPEC coatings were adopted by Raytheon through a block change process. Of the seven remaining alternatives, two materials-powder coating and 100% solids coatings-were ultimately chosen for validation testing.
