Silicone sealants are commonly used to seal gaps, joints, and crevices in buildings being constructed or renovated. Both professional and retail grade silicones are abundantly available for this purpose. These one-part silicone sealants cure by absorbing atmospheric moisture, which helps in the professional installation. A moistened finger or damp cloth is all that is needed to apply, and many do-it-yourselfers typically use this method to apply silicone caulking. Similar methods work for urethane caulking, the largest competitor of silicone caulking.

Silicone demand in the US will grow 4.7 percent annually through 2010, driven by performance and environmental advantages over acrylic, polyurethane, and rubber. Silicone fluids have, and will continue to have the highest demand. Demand for silicone gels will grow faster based on renewed growth in the electronics sector.

Silicone gels are essential to the electronics sector, where highly specialized applications call for greater demands on the sealing materials. Silicone rubber is used to insulate, seal and protect circuits, engine gaskets, control unit gaskets, electronic encapsulation, and special elements for decoupling noise.
