5 Main Features of NOVASTAR™ Silicone Water Repellent
- SHP80
- Others
- None
Outstanding Hydrophobic Performance
NOVASTAR™ Silicone hydrophobic powder can form a hydrophobic film on the surface of building materials to prevent water penetration and enhance water resistance. At the same time, when water vapor or raindrops in the air touch the surface of the material, NOVASTAR™ water repellent can exert an excellent water drop effect, which means that liquid water is difficult to stay on the slope or facade and rolls down in the form of water droplets, thereby preventing the outside from penetrating into the cement-based material.
Good Durability
Environment-friendly
NOVASTAR™ silicone water repellent has good environmental protection performance and will not cause pollution to the environment.
Gas Permeability
With good gas permeability, NOVASTAR™ silicone water repellent will not affect the gas permeability of the treated material.
Good Abrasion Performance
The powder helps the treated surface have a certain degree of wear resistance and can protect building materials from erosion by external factors.

Multiple Applications of NOVASTAR™ Waterproofing Agent
- Waterproof and moisture-proof
- Extended service life
- Enhanced hydrophobic ability
Silicone hydrophobic agents can significantly improve the hydrophobicity of repair mortar, reduce the penetration of water into the mortar, and thereby prevent damage and performance degradation caused by water. This characteristic makes the surface of the repaired mortar less prone to moisture, prolonging the service life of the repaired area.
- Intensified mechanical properties
NOVASTAR™ silicone hydrophobic agents do not affect the flexural and compressive strength of mortar; instead, they can enhance its anti-staining ability and maintain excellent brushing performance. This makes the repaired surface more solid and durable, capable of withstanding greater external forces and enhancing the stability of the overall structure.
Tile Grout
- Waterproof effect
Adding a silicone hydrophobic agent can effectively improve the water and moisture resistance of tile grout so as to achieve the waterproof effect. This helps in preventing water seepage and mold growth in tiled areas such as bathrooms, kitchens, and swimming pools.
- Uniform and anti-crack
In addition, it can make the tile grout stronger, preventing the tile grout from cracking and falling off during use. The addition of a silicone hydrophobic agent can make the tile grout more uniform, not uneven, and improve aesthetics.
- Enhanced hydrophobic
- Impermeability
Wall Putty
- Waterproof effect
- Good gas permeability

FAQs about Silicone Hydrophobic Powder
How Does Silicone Hydrophobic Powder Work?
After the mortar with silicone hydrophobic powder added is mixed with water, the protective colloidal shell of the silicone hydrophobic agent dissolves rapidly in water and releases the encapsulated organosilanes, which are re-dispersed into water;
The hydrophilic organic functional groups in silane hydrolyze to form highly reactive silanol groups；
The silanol groups react irreversibly with the hydroxyl groups in cement hydration products to form a chemical bond;
The chemically cross-linked silane is firmly fixed on the surface of the pore wall in the cement mortar, and the hydrophilic organic functional groups are oriented to the outside of the pore wall, which makes the pore surface hydrophobic, and the hardened mortar has a hydrophobic effect.
