The Canadian Coast Guard searched for a method to strip rust and marine coatings from navigational buoys. Specifications outlined the removal of 15 to 20 mils of high performance epoxy coatings, with near white blast preparation with a 3 to 4-mil [75-100 micron] profile. Although conventional abrasives could be used to complete the project, most could not be expected to minimize waste or to limit impact on surrounding operations and the environment. Silver Sponge Media TM abrasive was chosen based on the following process characteristics:
Low Airborne Dust - The facility was restricted to outdoor blasting and therefore wanted to limit releasing anti-foulant paint dust in the air. Sponge Media abrasives are porous and suppress up to 93% of what would normally become airborne dust.
