Silicone Hydrophobic Powder (SHP)
TENESSY - A Reliable Silicone Hydrophobic Powder Supplier
Silicone Hydrophobic Powder is a high-performance waterproofing additive designed to significantly improve the water-repellent capability of cement, gypsum, and various coating systems. By creating a “breathing” hydrophobic barrier on the surface of various coatings, it is possible to prevent water intrusion while maintaining the material’s breathability, ensuring long-term durability and preventing cracks or surface damage.
As a trusted manufacturer in China, Tenessy offers industry-leading silicone hydrophobic technologies with our flagship models engineered for superior dispersibility, excellent compatibility, and long-lasting protection. We also provide customized OEM solutions to meet the specific formulation requirements of different construction materials and application environments.
Key Functions of Silicone Hydrophobic Powder
Helps cement-based mortars and coatings resist water penetration from the inside out, making it ideal for applications that require deep waterproofing and moisture protection.
2. Creates Strong Water-Repellent “Beading Effect”Forms a hydrophobic surface that causes water to roll off like droplets on a lotus leaf. This prevents water from soaking into the material and greatly improves overall waterproof efficiency.
3. Reduces Water Absorption & Improves Stain ResistanceBy blocking water uptake, it reduces dampness, prevents stains, and helps the surface stay clean for a longer time, maintaining excellent hydrophobic performance over the long term.

Top Applications of Silicone Hydrophobic Powder
SHP from Tenessy is widely used in various dry-mix mortar systems to enhance waterproofing, reduce water absorption, and improve durability. By forming a long-lasting water-repellent barrier inside the material, it helps building products stay dry, clean, and structurally strong. Whether for waterproof mortars, decorative coatings, self-leveling floors, or tile grouts, this additive provides reliable protection and stability in both indoor and outdoor environments.
Waterproof Mortar
Suitable for polymer-modified waterproof mortar and rigid waterproof mortar, the powder enhances internal hydrophobicity, improves resistance to water penetration, and provides long-lasting protection for wet and high-moisture environments.
Decorative Mortar
Self-Leveling Mortar
Gypsum-Based Microcement & Dry-Mix Coatings
How to Use Tenessy Silicone Hydrophobic Powder
- Dry Mix with Other Materials
Add the silicone hydrophobic powder directly into dry-mix mortar formulas such as waterproof mortar, self-leveling flooring, or other dry-mixed building materials. Mix it evenly using appropriate mixing equipment.
- Recommended Dosage
Add 0.16%–0.3% of the total dry weight. This small amount is enough to achieve excellent water repellency and long-lasting durability.
- Mixing Procedure
- Pour the required amount of clean water into a mixing container.
- Slowly add the dry mix (including silicone hydrophobic powder) into the water while stirring.
- Avoid overly strong or high-speed mixing, as this may introduce excess air bubbles.
- Resting Time
After mixing, allow the mixture to sit for about 5 minutes (depending on other additives used). This helps the powder fully activate and ensures optimal hydrophobic effect.
