Silquest™ A-137

1 of 96 products in this brand
Silquest™* A-137 silane is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with minerals contained in concrete, masonry and other substrates. The monomer can penetrate deeply into a substrate, and then react to form an extremely durable protective surface surrounding each microscopic particle.

Recommeded Usage

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.
