BST-Si-007 Inorganic Silicone Nano Waterproofing & Anti-Staining Agent
BST-Si-007 is a solvent-based nano product prepared by a special process using nano inorganic silicone as the main material through nano cross-linking technology, featuring outstanding comprehensive performance such as waterproofing and anti-staining. The product uses anhydrous ethanol as the solvent and offers functions including rapid drying, super-hydrophobicity, anti-staining, antibacterial, moisture resistance, freeze-thaw resistance, anti-aging, and anti-weathering, extending the service life of materials with convenient application.
1. Environmentally friendly formula, free from formaldehyde and benzene series, non-toxic and friendly to the environment.
2. Rapidly penetrates into the substrate, forming crystallization both inside and on the surface of the substrate simultaneously, providing waterproofing while allowing breathability.
3. Super-hydrophobic characteristics with a hydrophobic angle >150°; sewage has minimal contact area with the substrate surface, delivering remarkable anti-staining and anti-penetration effects.
4. Fast drying speed, effectively preventing efflorescence of the substrate, slowing down cement-based weathering, and preventing moss growth on the substrate.
5. Long protection period — unless the protective layer is artificially removed, the protection effectiveness can last as long as the service life of the substrate itself.
