Silane Siloxane Concrete Sealer｜Deep-Penetrating Water Repellent
Product Overview:
Silane Siloxane Concrete Sealer is a high-performance, non-film-forming, penetrating water-repellent treatment formulated for absorbent substrates such as concrete, masonry, natural stone, sandstone, and cementitious surfaces.
By combining silane and siloxane technology, this product provides both deep internal chemical bonding and a durable hydrophobic surface layer. It effectively protects against water ingress, freeze-thaw damage, chloride intrusion, salt scaling, and rebar corrosion, while maintaining vapor permeability and preserving the original appearance of the substrate.
Key Features & Performance:
| Item | Performance |
|---|---|
| Penetration Depth | Approx. 3–6 mm (varies by porosity and substrate) |
| Water Repellency | Reduces water absorption by up to 95% (ASTM C642) |
| Chloride Resistance | Minimizes chloride ion ingress (ASTM C1202) |
| Durability | Protection lasts 5–10 years per application (depending on environment) |
| Surface Appearance | No gloss, no discoloration, no yellowing |
| Breathability | Allows vapor diffusion, prevents moisture entrapment |
| UV Stability | Resistant to UV degradation and weathering |
| Environmental Compliance | Low VOC (< 50 g/L), LEED-compliant |
