BST-Si-008 Water-based Fluorine-free Nano Waterproofing Agent
BST-Si-008 is a fluorine-free water-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. It offers functions including green environmental protection, safety and non-toxicity, rapid drying, hydrophobicity, anti-staining, moisture resistance, freeze-thaw resistance, anti-aging, and anti-weathering, extending the service life of materials with convenient application.
1. Water-based environmentally friendly formula, free from formaldehyde and benzene series, non-toxic and friendly to the environment.
2. Rapidly penetrates into the substrate, forming mesh-like inorganic silicone crystallization both inside and on the surface of the substrate simultaneously, providing waterproofing while allowing breathability.
3. Hydrophobic characteristics with a hydrophobic angle >120°; 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.
