Silicone Hydrophobic Powder (SHP): The Durable Waterproof Barrier for Construction Materials

Silicone Hydrophobic Powder (SHP) is a highly effective water-repellent agent, typically based on siloxane chemistry. As a powder additive, SHP is widely incorporated into dry-mix mortars, putties, and specialty cement products to significantly reduce the material’s water absorption and capillary suction. By forming a microscopic hydrophobic layer, SHP Powder imparts long-lasting Hydrophobic Performance and excellent Freeze-Thaw Resistance to building materials, making it crucial for enhancing construction durability.
