The commonly used water repellent for dry mix mortar the material's pores to repel moisture intrusion from outside. Since the small pores are blocked, the wall is not breathable; while the silicone hydrophobic powder can keep the building normally breathable and permanently waterproof. It is a new type of rigid waterproofing material with good application prospects.The breathable waterproof mortar can not only prevent external water, but also allow the moisture in the mortar to dissipate, which will not cause cracking and hollowing of the mortar.

Our silicone hydrophobic powder is a high molecular three-dimensional network of water repellent with excellent performance, good alkali resistance, strong breathability and external resistance. Adding an appropriate amount of silicone hydrophobic powder to dry-mix mortar products can reduce the water absorption rate of the mortar and can be widely used in mortar products(External wall insulation anti-crack mortar, water-resistant putty, grout) that require hydrophobic function. Since the material comes from natural inorganic substances, its hydrophobic function does not change with time and changes in the surrounding environment, making the mortar have stable hydrophobicity.

Its main functions:

—Reduce the water absorption of the plaster mortar in the external wall insulation system

—Reduce the water absorption of polystyrene particle insulation mortar and inorganic insulation mortar

—Reduce the water absorption of decorative mortar and inhibit the occurrence of efflorescence

—Prevent the water absorption and efflorescence of tile grouts

—Enhance the water repellency and impermeability of rigid waterproof mortar

—Enhance the impermeability of waterproof tile adhesive
