Sealants

DOWSIL Specialty Sealants by Dow

Silicone-based Dow sealants last longer and are more versatile than most organic polymer sealants. They are durable, one-part RTV sealants. These Dow industrial silicone sealants cure at room temperature to a tough, rubbery solid with exceptional performance characteristics. If the application calls for an industrial silicone sealant to withstand high temperatures or solvents, to bond glass or metal, to flow into cracks or voids, or to resist mildew, Dow has a RTV sealant for it.
