Whether you are looking for a fully formulated water or stain repellent or a
key ingredient in your surface protection formulation, Dow Corning manufactures
a wide range of silanes, siloxanes, and emulsions that can help solve your
construction / building formulating or surface treatment problems.
Water and Stain Repellents
Dow Corning® brand water and stain repellent materials are used to
hydrophobe and oleophobe surfaces, making them resistant to water and oil
ingress. These materials are usable in solvent- or water-based systems to
provide flexibility in formulating to meet VOC and ease-of-use requirements.
Our silane-based water and stain repellents are available for use in
formulations that penetrate a broad range of substrates, including:
-
Poured-in-place or pre-cast concrete
-
Concrete block
-
Sandstone / granite
-
Brick / tile
-
Wood
-
Gypsum / perlite
-
Limestone / marble
Our silane-based water repellents create an envelope of protection to extend
the life of substrates for years in the toughest environments by providing a
variety of benefits, including:
-
Excellent water repellency
-
UV stability
-
Reduced efflorescence
-
Water vapor permeability
-
Clear, uniform, neutral appearance
-
Reduced freeze-thaw damage
-
Long-term durability
-
Chloride ion resistance to deter reinforcing steel corrosion for concrete
structures
-
Stain resistance from water and oil-based agents
Other Surface Protection
Dow Corning also manufactures a range of silicates and siliconates for use
in formulating pore blocking sealers and consolidators.
Sealers fall into two main groups:
-
Pore blockers, which provide little penetration and instead form a resin
barrier on the concrete's surface. Pore blockers are further
distinguished by their ability to partially or fully fill the surface pores, a
capability not shared by hydrophobing agents.
-
Hydrophobing agents, that penetrate the material deeply. Hydrophobers
allow the concrete to breathe and do not interfere with the concrete cure.
Consolidators can extend the life of stone and concrete and are used
in a variety of restoration and flooring applications.
