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 Supply Silica dimethyl silylate/Fumed Silica oil soluble CAS 68611-44-9

This product is silica dimethyl silylate. Its CAS number is 68611-44-9. People likewise call it oil soluble fumed silica. It begins as normal fumed silica. After that, it obtains treated with dimethyldichlorosilane. This therapy changes its surface area.

The surface area ends up being hydrophobic. This indicates it pushes back water. This treatment is crucial. It makes the silica job well in oils. It makes the silica job well in solvents. It makes the silica work well in non-polar systems. Without treatment, normal fumed silica just suches as water.

This material resembles a great white powder. It feels cosy. It is really light. It has a massive surface. The particles are extremely small. They form loosened networks easily. This network traps liquid. This makes fluids thicker. It manages exactly how fluids flow.

Its major work is enlarging oils. It enlarges solvents. It thickens resins. It protects against clearing up in blends. It quits heavy components from sinking. It keeps mixtures secure over time. It boosts exactly how products use. It gives body to formulas. It aids control drooping. This works on vertical surfaces.

You discover it in numerous industrial items. It works in paints and finishings. It operates in publishing inks. It operates in adhesives and sealers. It operates in oils and lubes. It works in silicone items. It operates in cosmetic products. It functions where oil-based systems require thickening. It works where stability is needed.

Managing this powder requires treatment. Stay clear of breathing in the dust. Use it in well-ventilated locations. Use safety equipment. Shop it in a cool, dry location. Keep the container snugly closed. Shield it from dampness. Wetness can affect its performance.

The advantages are clear. It provides outstanding thickening. It provides great anti-settling homes. It improves product security. It is simple to spread. It functions well with several materials. It uses foreseeable efficiency. It is a trustworthy option for formulators. It fixes common troubles in oil-based systems.

Applications of Supply Silica dimethyl silylate/Fumed Silica oil soluble CAS 68611-44-9

This treated fumed silica (CAS 68611-44-9) works well in oils. Its surface area is hydrophobic. This makes it different from unattended silica. You find it in several markets needing oil-based systems.

It enlarges liquids efficiently. This is crucial for paints and coatings. It stops pigments and fillers from sinking. This keeps the color and efficiency regular. You get a smooth surface without brush marks. It helps control exactly how the paint flows. This makes application less complicated.

Lubing greases utilize it as well. It acts as the thickener. It traps the oil inside its structure. This produces the semi-solid grease. It supplies security. The oil stays under pressure and heat. It stands up to water washout. This keeps equipment protected longer.

Silicone products profit substantially. It reinforces silicone rubbers and sealers. This makes them stronger and much more durable. It boosts their resistance to tearing. It also enlarges silicone oils and pastes. This prevents splitting up. It makes sure the product performs reliably.

Cosmetics and personal care products use it. It thickens lipsticks, structures, and lotions. This gives them a positive, non-greasy feeling. It assists powders stay suspended in liquids. This quits separation in products like fluid make-up. It can additionally provide a matte finish.

Adhesives and sealants get boosted homes. It manages just how they flow and resolve. This stops drooping on upright surfaces. It enhances the treated product. This makes the bond stronger and much more durable. It assists handle thickness throughout application. This ensures accurate placement.

5 FAQs of Supply Silica dimethyl silylate/Fumed Silica oil soluble CAS 68611-44-9

What is Supply Silica dimethyl silylate?
It’s a special type of fumed silica. We treat its surface with dimethyl silyl groups. This process makes it oil soluble. The CAS number is 68611-44-9. It looks like a fine white powder.

Why is oil solubility important?
Regular fumed silica only works well in water. This modified version mixes easily into oils and solvents. You get a uniform dispersion. This prevents clumping. It improves performance in oil-based systems.

Where is this material typically used?
Its main use is in thickening oils and solvents. You find it in industrial coatings and paints. It helps control viscosity. It prevents settling in inks and adhesives. It improves the texture of greases and sealants. It works well in silicone rubber compounds.

Is it safe to handle?
Handle it like any fine powder. Avoid breathing in the dust. Wear suitable protective gear. This means gloves, safety glasses, and maybe a dust mask. Refer to the Safety Data Sheet (SDS) for full details. Follow all recommended safety practices.

How is it different from regular fumed silica?
Regular fumed silica is hydrophilic. It attracts water. Our dimethyl silylate version is hydrophobic. It repels water. It bonds strongly with oils. This gives better thickening in non-aqueous systems. The surface treatment changes its behavior completely.
