NOVASTAR™ Silicone Hydrophobic Powder: Powerful Water Repellent for Building Materials
What is Silicone Hydrophobic Powder (SHP)? A Cornerstone of Modern Construction
In the world of advanced building materials, Silicone Hydrophobic Powder (SHP) stands out as a critical additive for ensuring longevity and durability. Often referred to as a "waterproofing agent," SHP is a high-performance, free-flowing white powder. It consists of advanced silicone active ingredients on a mineral carrier, engineered to impart remarkable water-repellent properties to a wide range of cementitious, mineral-based products. When integrated into dry-mix formulations like mortars, grouts, or renders, SHP creates an integral hydrophobic barrier. This barrier dramatically reduces water absorption by capillary action, protecting structures from moisture ingress, efflorescence, and freeze-thaw damage, all without sealing the surface, thus allowing the structure to breathe.

The NOVASTAR™ Advantage: Key Features of Our Silicone Water Repellent
Unrivaled Hydrophobic Performance
NOVASTAR™ Silicone Hydrophobic Powder forms a permanent, bonded hydrophobic matrix within the pores of building materials. This creates a powerful beading effect, causing water to form droplets and roll off the surface rather than being absorbed. This mechanism, known as the lotus effect, provides a primary defense against water penetration, keeping substrates dry and structurally sound.
(Image Comparison: Visual evidence clearly shows surfaces treated with NOVASTAR™ SHP80 aggressively repelling water, in stark contrast to untreated surfaces or those with inferior hydrophobic agents which readily absorb moisture.)
Long-Lasting Durability
Unlike temporary surface coatings that degrade under UV exposure and weathering, NOVASTAR™ SHP provides integral and permanent protection. It chemically bonds with the substrate, ensuring the hydrophobic effect lasts for the entire lifespan of the material. This reduces long-term maintenance costs and preserves the building's aesthetic and structural integrity.
Environmentally Friendly and Breathable Protection
Engineered with sustainability in mind, NOVASTAR™ Silicone Hydrophobic Powder is a VOC-free formulation, making it an environmentally responsible choice for green building projects. Crucially, it does not form a film or seal the material's pores. This maintains the substrate's natural gas permeability, allowing water vapor to escape from within the structure and preventing issues like blistering, spalling, and mold growth caused by trapped moisture.
Enhanced Abrasion Resistance
By integrating into the material matrix, our SHP also contributes to enhanced surface durability. Treated materials exhibit improved resistance to abrasion and erosion from environmental factors, ensuring they maintain their original finish and performance for longer, even in high-traffic or harsh-weather environments.
Versatile Applications: A Solution for Every Building Material
The efficacy of NOVASTAR™ Silicone Hydrophobic Powder extends across a diverse range of dry-mix applications, providing targeted solutions to common construction challenges.
External Thermal Insulation Systems (EIFS)
In EIFS, moisture is the enemy. NOVASTAR™ SHP protects the insulation layer from water ingress, preserving its thermal performance. By ensuring the system remains breathable, it prevents moisture buildup within the wall assembly, extending the service life of the entire facade and preventing mold.
Repair Mortar
For structural repairs to be effective, they must be durable. Our SHP significantly enhances the hydrophobicity of repair mortars, preventing water from penetrating the repaired area. This is achieved without compromising critical mechanical properties like flexural and compressive strength, leading to a more robust and lasting repair.
Tile Grout
In high-moisture areas like bathrooms, kitchens, and swimming pools, tile grout is susceptible to water seepage, staining, and mold growth. Adding NOVASTAR™ SHP makes the grout intensely water-resistant, preventing these issues. It also strengthens the grout, reducing the likelihood of cracking and ensuring a uniform, clean, and aesthetically pleasing finish.
Waterproof Mortar
When used in waterproof mortars and renders, our Silicone Hydrophobic Powder drastically reduces the water absorption rate and increases resistance to hydrostatic pressure. This enhances the overall impermeability of the mortar, providing reliable, long-term protection for basements, foundations, and other critical waterproofing projects.
Wall Putty
NOVASTAR™ SHP enhances the performance of both interior and exterior wall putties. It creates a waterproof barrier that prevents dampness and efflorescence from migrating through the wall, while its high gas permeability allows the walls to "breathe," contributing to a healthier indoor environment and a flawless paint finish.

FAQs about Silicone Hydrophobic Powder
How Does Silicone Hydrophobic Powder Work?
The mechanism is a sophisticated chemical process. When the mortar containing SHP is mixed with water, the powder's protective shell dissolves, releasing organosilane molecules. These molecules hydrolyze to form highly reactive silanol groups. The silanol groups then react irreversibly with the hydroxyl groups present in the cement hydration products, forming a strong, permanent chemical bond. This orients the hydrophobic organic groups outward, lining the pores of the mortar and rendering the entire surface hydrophobic from within.
Is Silicone Hydrophobic Powder Environmentally Friendly?
Yes. NOVASTAR™ Silicone Hydrophobic Powder is designed to be environmentally friendly. It is free of volatile organic compounds (VOCs) and does not release harmful substances, making it a sustainable choice for modern construction.
What are the Storage Conditions for Silicone Hydrophobic Powder?
To maintain its efficacy, SHP should be stored in a dry place below 30°C, away from direct sunlight and moisture. If a package is opened but not fully used, it must be tightly resealed to prevent moisture intrusion from the air.
What's Your Silicone Hydrophobic Powder Minimum Order Quantity (MOQ)?
Our standard MOQ is 500kg. For specific inquiries or to discuss your project needs, please contact our sales team to learn more about purchasing NOVASTAR™ Silicone Hydrophobic Powder.
