The unique 100% silane treatment (no solvent) penetrates the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. The product creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration.
By combining low surface tension with a tailored rate of reaction, Protectosil® BHN PLUS is able to move through the moisture boundary layer that lines the pore structure of the substrate. This permits the development of uniform gradient permeation — a consistent level of protection throughout the entire depth of penetration — allowing for longer treatment life, especially on wearing surfaces.
- Low VOC
- Low-temperature application (20°F)
- Excellent long-term chloride screening on wearing surfaces (bridge decks, parking decks)
