Dow Corning Corp. announced the expansion of its stain- and water-repellent product line with the introduction of Dow Corning® 6706W and 6707W penetrating stain repellents. The products are described as water-based fluorosilane post-treatments that provide effective, environmentally sound water and oil repellency to porous construction materials such as concrete, natural stone, pavers, mortar, and grout.
The company says the products are UV stable, and allow the substrate to retain water-vapor permeability and their original appearance, while reducing dirt pick-up and contributing to easier cleaning.
The small molecular size of the stain repellents facilitates penetration into the surface, where the repellents chemically bond to most construction substrates, the company says. The resulting layer of hydrophobic protection reduces water absorption and the damage that can occur due to freeze-thaw cycles.
The 6706W repellent is a ready-to-use product; the 6707W repellent is a concentrate that can be diluted with soft water. Both products are solvent-free and will not damage glass, metal, wood, or most plastics.
