Silquest A-137 silane is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with the minerals contained in concrete, masonry and other substrates. The monomer can penetrate deeply into a substrate, and then react to form a protective surface surrounding each microscopic particle. This protective surface is extremely durable and leads to significant improvements in weather resistance. The silane is easily dissolved in organic solvents to form clear, colorless, stable solutions.

Applications: Penetrating sealers containing Silquest A-137 silane can provide excellent protection for bricks and stone.
