A selection of specialist products by Dow Dowsil


Dow Corning was formally established in 1943 as a joint venture between the American conglomerates Dow Chemical and Corning Glass to explore the potential of silicone and was a manufacturer of products for use by the U.S. military in World War II. Dow subsequently bought out Corning and Dow Corning became a 100% Dow subsidiary who are now wholly owned by Dow and specialize in silicone and silicon-based technology, being the largest silicone product producer in the world. In 2017 a new product brand name DOWSIL™ was announced for Heritage Dow Corning high-performance silicone building products. We stock the phenomenally successful Dowsil 7 Series (formerly known as The Dow Corning 7 Series) in it’s entirety along with other specialist Dowsil silicone mastic joint sealants.
