ENVIRONMENTALLY FRIENDLY ADHESIVES FOR ARMY APPLICATIONS

摘要

The adhesives and sealants thrust area of the SPOTA program has identified HAP-free alternatives to some of the most widely used adhesives in the Army. Laboratory testing shows that 3M Scotch-Weld 847 is a high-performing HAP-free and VOC-free replacement for the currently used adhesives conforming to MMM-A-121. A demonstration/validation study concluded the high performance of this low-HAP adhesive. For primary rubber to metal bonding, testing showed that non-HAP thinners can be used to replace HAP thinners and low HAP adhesive formulations can be used to replace baseline adhesive formulations. Overall, substituting these low HAP/HAP free adhesives with the baseline adhesives will reduce Army HAP emissions by ～5000 lbs/yr and VOC emissions by ～6000 lbs/yr while maintaining performance.
