Hydrophobic powder for sale in KINGSUN is a highly efficient active silicone powder. Only a small amount of addition is required to have excellent dispersibility in mortar. By reacting with cement hydration products, it can significantly improve the hydrophobicity and durability of cement-based materials. It has good compatibility with other additives in dry mortar. Silicone hydrophobic powder is a ternary fine particle composed of a powder carrier, a colloidal coating material and an easily dispersible silicone active ingredient. The colloidal coating material can stably store the active ingredient in the powder and release it in time after adding water. It can be used in decorative mortar, waterproof mortar, plastering mortar, caulking agent, thermal insulation mortar and prefabricated components. It is recommended to use hydrophobic agent with polycarboxylic acid water reducer, glue powder for better effect. When using, it can be stirred at a low speed with water added to the dry mixed mortar. If the stirring intensity is too high, a large number of bubbles are easily introduced.

Excellent Performance of Silicone Hydrophobic Powder
- It has excellent hydrophobic properties, good surfactant dispersion performance, and strong hydrophobicity.
- It can be used at low temperatures and can extend the service life.
- It has high acid and alkali resistance and is not corroded by pollutants.
- Like siloxane-based products, silicone hydrophobic powder can resist UV degradation.
- Hydrophobic powder has changed the traditional method of exterior wall waterproofing, starting from the structure of building materials, and solved the fundamental problem of exterior wall leakage.
- It can make the mortar and concrete gaps dense. It improves the compressive and tensile strength, so that the bonding between the insulation board and the wall does not expand, deform, or fall off, which can effectively extend the life of the building.
- The waterproof effect of using this additive can reach more than decades, and the cost is only about one-tenth of traditional waterproof materials. Siliconehydrophobicagent has the characteristics of acid and alkali resistance, aging resistance, carbonization resistance, alkali resistance, moisture resistance, and mildew resistance.
Cement-based materials. Adding silicone hydrophobic powder to cement-based materials can significantly reduce the water absorption rate of the material and prevent liquid water from penetrating through the surface or capillary action.
Mortar system. Adding hydrophobic powder to the mortar system can greatly reduce the water absorption rate, which is suitable for mortar systems that require hydrophobic requirements.
In applications such as plaster, plastering, caulking, exterior wall insulation system, decorative mortar and exterior wall painting, silicone hydrophobic powder can form a barrier to prevent liquid water from penetrating through capillaries.
Silicone hydrophobic powder releases active substances in the cement mortar system, reacts with the hydroxyl groups in the cement mortar, and combines into a good network structure. After the cement mortar is cured, the hydrophobic groups in the silicone play a role in reducing the surface energy, preventing water from invading, thereby reducing the water absorption rate of the cement mortar, and will not have a negative impact on the performance of the cement mortar itself.
The main function of silicone hydrophobic agent is to increase the hydrophobicity of the material, reduce water absorption, and prevent liquid water from penetrating. Specifically, silicone hydrophobic powder can be applied to various substrates (such as cement, mortar, etc.) to form a transparent protective film to improve the water resistance, stain resistance and temperature resistance of the material.
Silicone type hydrophobic powder. The main component is an organic silane substance containing active groups, which is made into dry powder type silicone hydrophobic powder after active protection and drying. It has excellent dispersibility in water.
Multi-polymer hydrophobic powder. The main component is a mixture of lipid organic products, which is hygroscopic in the air and insoluble in water.
