Small scratches or weld burns through the epoxy coating will not adversely impact product efficacy. The silver ions contained within the ceramic matrix can still diffuse and migrate to the microbes within the scratch. The active silver ions can “bridge” up to a 1/4-inch gap. Numerous or wide scratch patterns will reduce the efficacy of the product. Contact the McGill AirFlow sales engineering office nearest you to order SilverGuard ductwork epoxy paint for touch-ups.
