Silicone hydrophobic powder is a kind of effective hydrophobic water repellent used in cement-based products, which can improve the long-term water resistance of cement-based products, protect the surface and interior of cement-based building materials from water penetration, and improve the overall hydrophobicity of the products. Its excellent dispersibility in water makes the dry powder system have the corresponding properties of liquid silicone hydrophobic material. The product has silicone active ingredients which are easy to disperse. Its active ingredients can be stably stored in the powder, and it can be released in time after adding water. This product can be applied to all kinds of substrates that need to prevent liquid water infiltration or have good hydrophobic effect on the surface.
Like other silane-based products, the mortar added with silicone hydrophobic powder has good waterproof, hydrophobicity and impermeability.

Silicone hydrophobic powder is a dry powder material. When using this product, it should be added to the dry material of cement-based mixture, but the mixing time should be shortened as much as possible to avoid the temperature increase caused by high shear force. * Good addition amount should be determined through experimental evaluation. In most applications, the addition amount of silicone hydrophobic powder in dry ingredients is 0.1%- 0.3% by weight. If there is a high demand for hydrophobic state, the dosage can be appropriately increased.
