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 ~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. Identifying a HAP-free adhesive that conforms to MMM-A-121 is a high priority for the Army. 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 and Clifton E-1293 adhesive for specification MMM-A-121. Based on 2003 data, switching from the baseline Clifton E-1293 or 3M-1357 to the alternative 3M-847 would mean an Army-wide reduction of over 1000 lb/year of HAP emissions. This report details the methods for field testing adhesive on an aviation helmet (model no. HGU-56/P) "edge beading"preventative maintenance/repair, an Army UH-60 Blackhawk helicopter "nose door seal",and for general Army use conducted at Lowe Army Heliport, Fort Rucker, AL. Furthermore, this report details the identification and solution of several previously undocumented issues associated with substrate materials currently used by the Army, resulting in modified adhesive application procedures and updated laboratory tests related to the MMM-A-121 specification.
