Hot melt silicone-based sealant technology from Dow Corning replaces drilled bolts and rivets on watercraft. Traditional boat assembly and part joining can provide an avenue for water to leak into the instrument panels, cockpit cabinets, cabin, and hull. The drilled holes create pockets for moisture and debris to accumulate, which can lead to leaks, corrosion, contamination, and potential screw loosening. Bolts and screws also concentrate tension into stress points that can result in fatigue, crazing, and cracking. The hot melt sealant forms a bond almost immediately, eliminating bottlenecks, and is more flexible than mechanical fasteners by absorbing much of the stress caused by thermal expansion. In addition, silicone sealant adheres well to materials commonly used in boat assembly such as metal, wood, painted surfaces, glass, and plastics.
