The hydrophobic treatment modifies the surface of the silicon dioxide particles, making them water-repellent. This treatment
involves the attachment of hydrophobic groups, such as methyl or phenyl groups, to the surface of the particles. The hydrophobic
groups create a barrier that prevents water from wetting the surface of the particles.
Hydrophobic silica treatment is a process used to make surfaces water-repellent or hydrophobic. Silica, a naturally occurring
mineral, is treated with hydrophobic compounds or coatings to alter its surface properties. This treatment creates a thin layer
on the surface that repels water, preventing it from soaking in or causing damage.
The hydrophobic silica treatment is commonly used on various surfaces, including glass, concrete, metal, and textiles. It provides
several benefits, such as:
1. Water repellency: The treated surface becomes water-resistant, preventing water from penetrating or causing damage. This is particularly useful in areas prone to heavy rainfall or water exposure.
2. Stain resistance: Hydrophobic silica treatment can also make surfaces resistant to stains, as liquids and dirt are unable to adhere
to the treated surface easily. This makes cleaning and maintenance easier.
3. UV resistance: Some hydrophobic silica treatments also offer UV resistance, protecting the surface from the damaging effects of
the sun's rays. This can help prevent fading, discoloration, and deterioration of the material.
4. Increased lifespan: By repelling water and protecting against stains and UV damage, hydrophobic silica treatment can extend
the lifespan of the treated surface. This can help save on maintenance and replacement costs in the long run.
Hydrophobic silica treatments are available in various forms, including sprays, coatings, and impregnating agents. The specific application method may vary depending on the surface being treated and the desired level of water repellency.
It is important to note that hydrophobic silica treatment is not permanent and may require reapplication over time, especially in high
-traffic or heavily exposed areas. Additionally, the effectiveness of the treatment can vary depending on the quality of the product
used and the surface being treated.
