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 Fumed Silica Hydrophilic Silica Precipitated SiO2 Paint Coatings Agent Thickening Reinforcing Filling Other Carbon Carbon Black

This powder product combines silica types. You get fumed silica and precipitated silica. Both are hydrophilic. This means they attract water. They work together well. This powder also includes carbon black. Think of them as distinct additives in one package.

Fumed silica offers high performance. It has tiny particle size. It provides a huge surface area. This makes it powerful. It thickens liquids effectively. It prevents settling. It controls flow. Use it where top performance matters. Precipitated silica is important too. It offers good reinforcement. It fills space efficiently. It is often more economical. It provides bulk. It improves texture. It adds strength.

These silicas thicken many products. They work in paints and coatings. They work in adhesives and sealants. They work in resins and gels. They make liquids thicker. They stop sagging or dripping. They help the product stay put. They reinforce materials too. They make coatings harder. They make plastics tougher. They resist abrasion better. They fill gaps. This improves smoothness. It reduces shrinkage. It saves on cost sometimes.

Carbon black serves different purposes. It provides strong black color. It offers UV protection. It shields materials from sunlight damage. It adds conductivity. It helps control static electricity. It reinforces rubber heavily. It is vital for tires.

Consider the product specifications. Particle size varies by silica type. Surface area is high for fumed silica. Density is low. It feels light and fluffy. Purity is generally very good. Check the specific grade data sheet. This ensures it meets your needs. The combination offers flexibility. You get thickening power. You get reinforcing strength. You get filling capacity. You get color and protection from carbon black. This handles multiple formulation needs efficiently. Use it in demanding industrial applications. It works well in paints and coatings.

Applications of Fumed Silica Hydrophilic Silica Precipitated SiO2 Paint Coatings Agent Thickening Reinforcing Filling Other Carbon Carbon Black

Fumed silica is a versatile material. Hydrophilic silica works well in water-based systems. Precipitated SiO2 offers similar benefits often at lower cost. These silica types are important in many industries. Paint and coatings rely heavily on them. They act as thickening agents. This prevents pigments from sinking to the bottom. It keeps the mixture stable during storage. Application becomes smoother too. The paint flows better onto surfaces. It avoids drips and splatters. The final finish looks more even and professional.

These silicas also reinforce the coating. They make the dried film tougher. It resists scratches and abrasion better. The coating lasts longer. Its durability improves. This reinforcement is valuable for industrial paints and protective coatings. Silicas help control gloss levels. They can create matte or satin finishes. This is important for decorative paints.

Beyond thickening and reinforcing, silica acts as a filler. It adds bulk to the product. This reduces the overall cost. It replaces some expensive ingredients. The performance remains high. Carbon black serves a different primary purpose. It provides strong black color and UV protection. It also reinforces rubber and plastic products. Like silica, carbon black is a filler too. It adds volume cost-effectively. Both materials are essential workhorses. They improve product performance and manufacturing economics. Other industries use them similarly. They thicken adhesives and sealants. They reinforce silicone rubber. They prevent caking in powders. They manage flow in food and pharmaceuticals. Their small particle size and high surface area create these effects.

5 FAQs of Fumed Silica Hydrophilic Silica Precipitated SiO2 Paint Coatings Agent Thickening Reinforcing Filling Other Carbon Carbon Black

What is fumed silica?
Fumed silica is a fine white powder. It’s made from silicon tetrachloride vapor burned in a hydrogen-oxygen flame. This process creates tiny particles. These particles have high surface area. Hydrophilic fumed silica attracts water. It’s different from hydrophobic types.

What does it do in paint and coatings?
It mainly thickens paint. This prevents sagging on vertical surfaces. It also acts as a reinforcing filler. This makes the paint film harder. It improves scratch resistance. It helps control gloss levels too. It stops pigments from settling.

Why use fumed silica over precipitated silica?
Fumed silica gives much stronger thickening. You need less of it. Its tiny particle size works better. It offers superior reinforcement. This means better durability. The quality is often higher. Precipitated silica is cheaper but less effective.

How much should I add to my paint?
The amount varies a lot. It depends on your specific paint formula. It also depends on the desired thickness. Start with a small amount. Try 0.5% to 2% by weight. Increase slowly if needed. Test it thoroughly. Too much makes the paint hard to spread.

Is it hard to mix into paint?
Mixing requires care. The powder is very light. It can become dusty. Add it slowly while mixing fast. Use a high-shear mixer. This prevents clumps. Mix until fully smooth. Good dispersion is key for performance. Wear a dust mask.
