Protectosil® WS CIT 200

Clear, VOC-compliant reactive penetrating sealer with a migrating corrosion inhibitor. 50% active ingredients.

PRODUCT OVERVIEW:

The next-generation silane corrosion inhibitor. A clear, pen-etrating, breathable VOC-compliant organofunctional silane reactive penetrating corrosion inhibitor surface treatment for use on concrete. The organofunctional silane allows for superior performance on high quality mix designs typical of new bridge decks and can also be used on existing structures with active corrosion. Creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration.

APPLICATIONS:

For use on cast-in-place, pre-cast, and high-strength concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and carbonation. Alleviates deterioration of concrete due to alkali-silica reactivity. For protecting concrete structures such as parking and bridge decks, columns and beams, piers, sea walls, sidewalks, balconies, driveways, roads and other steel-reinforced concrete structures.
