Silicone Hydrophobic/ Repellent Agent Powder

Silicone Hydrophobic Agent Is a new type of rigid waterproof material for building with good permeability and crystallinity. Crosslinking reaction happens between Si-Oh in themolecular structure and Si-OH in silicate materials under the condition of moisture. So called “anti-capillary effect” occurs to form an excellent waterproof layer. At the same time, it will have the effect of microdilatancy and increasing the compactnesss.
