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 AEROSLR 974 Hydrophobic fumed silica Grades

AEROSIL R 974 is hydrophobic fumed silica. This means it drives away water. It is made by dealing with hydrophilic fumed silica with an unique representative. This agent makes the surface area water-hating.

This therapy provides R 974 key benefits. It blends conveniently into non-polar fluids. It quits water from influencing the powder. It keeps moving freely also in damp air. It works well in systems needing low moisture.

R 974 is available in several grades. The grades vary generally in their area. Surface is determined in square meters per gram (m TWO/ g). A higher area generally means more powerful thickening impacts. Usual qualities include R 974 S, R 974, and R 974 HD. Each quality targets certain performance requirements.

Below are the typical specifications for AEROSIL R 974 grades:
Chemical Nature: Hydrophobic silica.
Surface Treatment: Dimethyldichlorosilane.
Ordinary Key Bit Size: Around 12 nanometers. This is extremely tiny.
Details Area (WAGER): This differs by grade. R 974 S is about 170 ± 20 m TWO/ g. Standard R 974 is about 200 ± 25 m ²/ g. R 974 HD provides concerning 250 ± 30 m ²/ g.
Tamped Density: About 50 grams per litre (g/l). This reveals it’s a really light powder.
Loss on Drying (2 hrs at 105 ° C): Typically much less than 1.5%. This verifies its reduced dampness.
pH Value (in 4% diffusion): Around 3.7 to 4.7. It is somewhat acidic.
Carbon Web Content: Usually between 0.7% and 1.3%. This originates from the surface area therapy.

AEROSIL R 974 is extensively used. It functions as a thickener in adhesives and sealers. It reinforces silicone rubber. It regulates flow in paints and coverings. It stops caking in powders. It aids procedure plastics. Its hydrophobicity is critical for these jobs. It makes sure stability where water is an issue. Customers choose the particular quality based upon the needed thickening power and application.

Applications of AEROSLR 974 Hydrophobic fumed silica Grades

AEROSIL R 974 hydrophobic fumed silica takes on dampness issues. It drives away water efficiently. This property makes it essential for many demanding products. Sealants and adhesives profit significantly. Adding R 974 improves their water resistance. This protects against failing in damp problems. Assume construction joints exposed to rainfall. Industrial finishes acquire toughness. R 974 assists the coating withstand water infiltration. This stops rust on steel surface areas. It also avoids blistering. The result is longer-lasting protection.

Paints and inks do better with R 974. It controls flow and prevents drooping. Surface areas look smoother. The finish is a lot more professional. R 974 quits pigments from clearing up. Your paint shade remains consistent. Dampness sensitivity ruins numerous powders. R 974 serves as a flow help. Powders circulation openly. They resist clumping brought on by humidity. This makes sure trustworthy processing and handling. Silicone rubber needs reinforcement. R 974 enhances the rubber. It preserves thickness during processing. The final product has much better mechanical properties. It stands up to water damage.

Cosmetics use R 974 for structure. It offers lotions and lotions an elegant feeling. The item spreads out conveniently. It takes in quickly without greasiness. R 974 stabilizes formulations. It avoids separation. Free-flowing food powders need anti-caking agents. R 974 maintains powders completely dry and streaming. It avoids swellings in storage space. This is essential for instant beverage blends. Rheology control is another key feature. R 974 enlarges fluids without excessive heat. It supplies steady suspension. The viscosity stays consistent. This ensures predictable application each time. Efficiency under humid problems defines several items. R 974 guarantees integrity when wetness is present.

5 FAQs of AEROSLR 974 Hydrophobic fumed silica Grades

What is AEROSIL R 974?
AEROSIL R 974 is a special fumed silica powder. It is treated to repel water. This makes it hydrophobic. It acts as a thickener and reinforcing filler. It improves how liquids flow and handle. It prevents settling in mixtures.

How does the hydrophobicity work?
The silica particles get a surface treatment. This treatment uses chemicals. These chemicals make the surface dislike water. The particles won’t absorb water easily. This keeps the powder free-flowing. It also helps the silica mix better into non-water systems.

Where is AEROSIL R 974 typically used?
It is common in silicone rubber compounds. It thickens liquid systems effectively. It reinforces adhesives and sealants. It is used in coatings needing water resistance. It finds use in cable insulation. It is also used in gel coats and unsaturated polyester resins.

How is it different from untreated fumed silica?
Untreated fumed silica loves water. It absorbs moisture from the air. This causes clumping. R 974 resists moisture. It stays dry and pourable. It performs better in materials needing water repellency. It often gives better reinforcement in rubber. It provides better thickening in non-polar liquids.

Is AEROSIL R 974 safe to handle?
Handle it like any fine powder. Avoid breathing in the dust. Use good ventilation. Wear a dust mask. Wear safety glasses. Skin contact is usually okay. Wash skin after handling. Always check the safety data sheet for specific details. Follow the recommended safety practices.
