Description
Si Sealers – Siliconates, Silanes & Siloxanes
Si Chemistry: Si based water repellent sealers are usually applied in the form of siliconates, silanes and/or siloxanes. They are typically very small to medium sized molecules that when applied onto a substrate, penetrate deep below the surface. They chemically react with the substrate to form a cross-linked Si backbone polymer which repels water whilst still allowing vapour transmission.
Key advantages
- Superior water repellence, providing excellent water based stain resistance
- Reduces water ingress and minimises efflorescence in mineral substrates
- Transparent, natural finish – does not significantly change appearance
- High penetration into masonry surfaces
- High wear resistance, UV stable, long life
- Fungal and algal resistance
- Easy to clean surfaces
- Substrates remain breathable
- Can be applied to damp or wet substrates
