NOVASTAR™ SHP: High-Performance Silicone Hydrophobic Powder for Superior Water Repellency
Water ingress is the silent enemy of construction, leading to material degradation, structural weakness, and mold growth that compromises both the longevity and safety of a building. To combat this, construction professionals require a powerful, reliable, and long-lasting water repellent. SHANDONG LANDU, with its premium NOVASTAR™ brand, delivers the ultimate solution: a high-performance Silicone Hydrophobic Powder (SHP) designed for superior and durable water repellency.
This comprehensive guide explores the science, applications, and unparalleled advantages of using NOVASTAR™ SHP, establishing why it is the trusted choice for manufacturers and builders worldwide.
What is Silicone Hydrophobic Powder (SHP)?
Silicone Hydrophobic Powder, commonly abbreviated as SHP, is a highly efficient and versatile chemical additive engineered for its remarkable water-repellent properties. It is a fine, free-flowing white powder based on advanced silane/siloxane technology. When integrated into cementitious or other building materials, this powdered additive modifies the surface characteristics at a molecular level. It creates a powerful hydrophobic barrier that actively repels water, preventing it from penetrating the substrate. Due to its efficacy, Silicone Hydrophobic Powder is a critical component in a wide range of industrial applications, including tile grout, waterproof mortar, repair mortars, and EIFS, to impart integral and lasting waterproofing qualities.

Core Benefits of NOVASTAR™ Silicone Water Repellent
Outstanding Hydrophobic Performance (The Beading Effect)
NOVASTAR™ Silicone Hydrophobic Powder forms a durable, micro-porous hydrophobic film on the capillary walls of building materials. This barrier effectively prevents water penetration while enhancing overall water resistance. When water vapor or raindrops encounter the treated surface, NOVASTAR™ water repellent produces an excellent "beading effect." This means liquid water cannot wet the surface; instead, it forms droplets that roll off, preventing external moisture from penetrating the cement-based material.

Long-Lasting Durability
A surface treated with NOVASTAR™ Silicone Hydrophobic Powder exhibits exceptional durability. It maintains its powerful hydrophobic effect for an extended period, significantly resisting weathering and UV degradation. This long-term performance helps prolong the lifespan of the construction and reduces maintenance cycles and costs.
Environmentally Friendly and Safe
NOVASTAR™ silicone water repellent is designed with sustainability in mind. It is free from volatile organic compounds (VOCs) and does not cause pollution to the environment, making it a responsible choice for green building projects.
Maintains Substrate Breathability (Gas Permeability)
While providing outstanding water repellency, NOVASTAR™ does not seal the pores of the material. It maintains excellent gas permeability, allowing the substrate to "breathe." This crucial feature permits water vapor from within the structure to escape, preventing moisture buildup, dampness, and associated problems like mold and efflorescence.
Enhanced Abrasion Resistance
The powder helps impart a certain degree of wear resistance to the treated surface. This protects building materials from physical abrasion and erosion by external factors, contributing to the overall resilience of the structure.

Versatile Applications of NOVASTAR™ Waterproofing Agent
External Thermal Insulation System (EIFS)
- Ultimate Waterproofing and Moisture-Proofing: NOVASTAR™ SHP forms a water-repellent film on the surface of the EIFS base and finish coats, protecting the insulation layer from moisture ingress. By maintaining breathability, it prevents interstitial condensation and mold, safeguarding thermal performance.
- Extended System Service Life: The exceptional durability of our SHP ensures it remains effective under UV radiation and atmospheric aging. This guarantees the waterproof effect lasts for many years, significantly extending the service life of the EIFS.
Mortero de reparación
- Enhanced Hydrophobic Ability: Integrating SHP significantly improves the hydrophobicity of repair mortar, drastically reducing water penetration. This characteristic makes the repaired surface less prone to moisture damage, freeze-thaw cycles, and re-bar corrosion, prolonging the life of the repair.
- Intensified Overall Strength: NOVASTAR™ SHP achieves its hydrophobic effect without negatively impacting the flexural and compressive strength of the mortar. It makes the repaired surface more solid and durable, enhancing the stability of the overall structure.
Lechada para baldosas
- Superior Waterproofing Effect: Adding our SHP effectively improves the water and moisture resistance of tile grout. This is crucial for preventing water seepage and mold growth in perpetually wet areas like bathrooms, kitchens, and swimming pools.
- Improved Uniformity and Anti-Crack Properties: SHP promotes a stronger, more uniform grout matrix that is less prone to cracking and falling off during use. It improves the aesthetic finish by ensuring a consistent, non-blotchy appearance.
Waterproof Mortar
- Reduced Water Absorption: Silicone hydrophobic powder dramatically reduces the water absorption rate of the mortar, decreasing erosion and damage caused by water.
- Increased Impermeability: It significantly increases the impermeability and hydrostatic pressure resistance of the mortar. In critical waterproofing projects like basements and water tanks, the application of SHP can effectively extend the project's service life and enhance its waterproofing integrity.
Masilla de pared
- Powerful Waterproofing: Our silicone water repellent greatly enhances the waterproof performance of wall putty, preventing water from penetrating the interior wall and thus avoiding issues like dampness, peeling paint, and mold.
- Excellent Breathability: Despite being waterproof, the treated putty remains breathable. This allows moisture vapor to escape from the wall, preventing dampness-related issues while maintaining the wall's natural breathing function.

FAQs about Silicone Hydrophobic Powder
How Does Silicone Hydrophobic Powder Work?
The hydrophobic effect is created through a four-step chemical process within the mortar:
- Release: After mixing with water, the powder's protective shell dissolves, releasing active organosilane molecules.
- Hydrolysis: The hydrophilic groups in the silane hydrolyze, forming highly reactive silanol groups.
- Bonding: These silanol groups react irreversibly with the hydroxyl groups in cement hydration products, forming a permanent chemical bond.
- Orientation: The chemically bonded silane aligns its hydrophobic organic groups outwards, making the pore surfaces water-repellent and creating an integral hydrophobic effect throughout the hardened mortar.
Is Silicone Hydrophobic Powder Environmentally Friendly?
Yes, NOVASTAR™ Silicone Hydrophobic Powder is environmentally friendly. It is free of volatile organic compounds (VOCs) and does not release harmful chemicals into the environment, aligning with modern green building standards. You can learn more about its compliance on the ECHA website.
