Abstract: The goal of the Sustainable Painting Operations for the Total Army (SPOTA) program is to significantly reduce the amount of hazardous air pollutant (HAP) emissions produced in coating operations, including adhesives application and removal. Adhesives and sealants account for approximately 5% of U.S. Army-wide HAP emissions from surface coating operations. Materials conforming to Federal specification MMM-A-121 have been identified as one of the largest contributors. The purpose of this research is to demonstrate and validate the HAP-free alternative adhesive 3M-847 in place of the baseline materials 3M-1357, Clifton E-1293, and 3M-1300L adhesive for specification MMM-A-121. Based on 2003 data, switching from the baseline adhesives to the alternative 3M-847 would mean an Army-wide reduction of over 1000 lb/year of HAP emissions. This report summarizes the methods for successfully field testing adhesive on an aviation helmet (model no. HGU-56/P) "edge beading" preventative maintenance/repair and a U.S. Army UH-60 Black Hawk helicopter "nose door seal", conducted at Lowe Army Heliport, Fort Rucker, AL. An additional field trial was conducted at Anniston Army Depot, AL, on a Stryker infantry carrier vehicle drivers' access hatch seal with successful results. In particular, technicians found that processing the alternative adhesives was similar to that of the baseline, and after 6 months, the adhesive did not have any signs of blistering, delamination (either cohesively or adhesively), substrate failure, or deterioration of any kind. Overall, the HAP-free 3M-847 adhesive was qualified for use on MMM-A-121 requisite substrates, such as vulcanized rubber (styrene-butadiene rubber, neoprene, and nitrile) bonded to unpolished steel, in addition to alternative substrates, such as silicone rubber and lightweight composite materials, showing a high versatility to the 3M-847 adhesive.
