Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of High-Purity Nano-Powder Hydrophobic Fumed Silica Hydrophobic Silicon Dioxide Ht-903 for Coating

This high-purity hydrophobic fumed silica powder, HT-903, is developed for requiring finish applications. It’s silicon dioxide refined at severe temperatures, developing nano-sized bits. A special treatment makes the surface area repel water properly. This therapy makes use of hexamethyldisilazane.

The pureness is extremely high, surpassing 99.8%. This ensures constant performance and avoids presenting undesirable elements. The key fragment size is very little, generally 7-40 nanometers. This nano-scale framework is key to its feature.

In finishes, HT-903 uses significant benefits. Its hydrophobic nature protects against water absorption. This enhances the covering’s resistance to water damages and blistering. It assists keep performance in humid settings. The powder likewise functions as a thickener and anti-settling representative. It keeps pigments and fillers put on hold evenly. This avoids tough settling during storage. The result is simpler application and an extra consistent last movie.

HT-903 improves the flow and leveling of fluid coverings. It minimizes concerns like drooping on upright surfaces. The nano-particles strengthen the cured layer film. This enhances scrape resistance and overall sturdiness. It additionally helps in reducing frothing during mixing and application. Lower foam means fewer surface defects.

This powder is suitable for high-performance systems. Instances include commercial protective coverings, automobile surfaces, and marine paints. It works well in epoxy, polyurethane, and acrylic solutions. Its stability makes it suitable for solvent-based and solvent-free finishings. The essential benefit is creating tougher, longer-lasting finishes that endure wetness.

Applications of High-Purity Nano-Powder Hydrophobic Fumed Silica Hydrophobic Silicon Dioxide Ht-903 for Coating

HT-903 hydrophobic fumed silica is a special powder for coverings. It makes coatings much better at resisting water. This powder is really pure. Its fragments are very small. They are treated to be hydrophobic, implying they hate water. This therapy is key for its efficiency.

Adding HT-903 to your covering formula does several essential points. Initially, it significantly boosts water resistance. Coatings remain clear and solid also in wet conditions. This stops blistering and peeling. Second, it makes the finish surface harder. This improves scrape resistance. The finish lasts longer looking great. Third, it acts like a thickener. It regulates how the liquid finish flows. This stops drips and sags on upright surfaces. Fourth, it helps the finish spread equally. You obtain a smoother, nicer coating without brush marks or orange peel.

The powder operates in several covering kinds. Utilize it in solvent-based paints, varnishes, and commercial finishes. It also works well in some water-based systems needing extra water defense. It blends easily right into the coating fluid. You get regular outcomes batch after batch. Formulators choose HT-903 due to the fact that it resolves typical issues. It provides high efficiency reliably. It’s a proven service for demanding layer applications. Just include it throughout manufacturing.

5 FAQs of High-Purity Nano-Powder Hydrophobic Fumed Silica Hydrophobic Silicon Dioxide Ht-903 for Coating

What is HT-903?
HT-903 is a special fine powder. It’s made from silicon dioxide. We treat it to be hydrophobic. This means it strongly repels water. Its particles are extremely small, nano-sized. This powder is very pure.

Why is hydrophobic important for coatings?
Water can damage coatings. It causes problems like blistering or poor adhesion. Hydrophobic fumed silica fights water. It stops water from soaking into the coating. This makes the coating last longer. It protects the surface underneath much better.

What benefits does HT-903 give coatings?
HT-903 improves several key properties. It makes the coating resist water effectively. It prevents the coating from sagging during application. It helps control how thick the coating feels. It makes the surface feel smooth and dry. It can also help the coating resist dirt.

How do I use HT-903 in my coating?
You mix HT-903 into the coating liquid. Do this during the grinding stage. Good dispersion is critical. You must mix it thoroughly. Use the right amount for your specific formula. Follow the supplier’s guidelines closely. Testing small batches first is smart.

Is HT-903 safe to handle?
Handle HT-903 as a fine powder. Avoid breathing the dust. Use it in a well-ventilated area. Wear a dust mask. Wear gloves. Wear safety glasses. Follow standard safety rules for handling powders. Refer to the Safety Data Sheet for full details.
