Background. The Sustainable Painting Operations for the Total Army (SPOTA) Program was initiated in anticipation of impending National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations such as the Defense Land Systems and Miscellaneous Equipment (DLSME). Red River Army Depot (RRAD) manufactures roadwheels and track pads for use on tracked vehicles by the DoD. The Rubber-to-Metal Bonding (RTMB) process uses an adhesive that is applied to metal cores, allowed to dry, and then crosslinked when the rubber is molded to the core in an injection mold process. Current materials in this process contain xylene which is a hazardous air pollutant (HAP). HAP emission reduction will help RRAD comply with the impending DLSME NESHAP.
