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.

Potential Applications

Penetrating sealers containing Silquest A-137 silane can provide excellent protection for bricks, stone, masonry, wood and other substrates. Surfaces can be put into service within a few minutes. The performance of many existing water-repellent, sealer, stain and coating formulations can also be enhanced by the addition of Silquest A-137 silane and/or other Silquest silanes.

The dispersibility and compatibility of filler and pigment particles in coating and sealant formulations can be improved by adding Silquest A-137 silane to the coating formulation, or by using it as a pre-treatment for the pigments. The particulate surface is made more hydrophobic and organic-like. Consequently, it becomes more compatible with typical coating, adhesive and sealant vehicles.
