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 Aerosil 300 Silica-based Fumed Silica Evonik Hydrophilic Fumed Silica for Paint Coating HTV Silicone Rubber Adhesives Sealants

Aerosil 300 is a kind of fumed silica made by Evonik. It is hydrophilic silica. Hydrophilic implies it attracts water. This white powder is extremely fine. Its particles are incredibly little. The surface area is big, about 300 square meters per gram. This big area offers it distinct buildings. It acts as a thickener and a reinforcing representative. It additionally helps stop resolving.

In paints and coverings, Aerosil 300 works. It enhances viscosity and protects against drooping. Drooping occurs when paint runs down vertical surfaces. It improves the application homes. The paint streams far better and degrees out nicely. It assists regulate the gloss of the finish. It makes the paint much more resilient and resistant.

For HTV silicone rubber, Aerosil 300 offers support. It makes the rubber stronger and harder. It boosts the tear resistance. The rubber becomes harder. Processing the rubber is easier as well. The mechanical homes get better. The rubber carries out well under stress.

In adhesives and sealants, Aerosil 300 is very important. It enlarges the material properly. It quits fillers from settling to the bottom. It boosts the application feel. The glue or sealant keeps where you place it. It improves the overall stamina and performance. The bond or seal lasts much longer.

The typical residential or commercial properties are specific. The wager area is 300 m TWO/ g. The typical key bit dimension is 7 nanometers. The tamped density is around 50 grams per litre. The pH value in water suspension has to do with 3.7 to 4.7. It is a versatile additive for lots of industries. Its little dimension and high surface area drive its efficiency.

Applications of Aerosil 300 Silica-based Fumed Silica Evonik Hydrophilic Fumed Silica for Paint Coating HTV Silicone Rubber Adhesives Sealants

Aerosil 300 is a fumed silica made by Evonik. It is hydrophilic. This implies it attracts water. The silica has a very high surface area. This gives it useful buildings in numerous items.

In paints and finishes, Aerosil 300 is necessary. It thickens the liquid. This quits the paint from dripping or sagging on vertical surfaces. It helps the paint remain where you apply it. The silica additionally quits pigments from resolving at the end of the canister. Your paint remains mixed longer. It improves just how the layer moves during application. This offers a smoother surface.

For HTV silicone rubber, Aerosil 300 is a key reinforcement. HTV silicone requires strength. Including Aerosil 300 makes the rubber much more powerful. It boosts tear resistance. The rubber doesn’t tear quickly. It likewise assists the rubber maintain its shape under stress and anxiety. The material performs far better.

Adhesives utilize Aerosil 300 as well. It regulates just how the adhesive moves. The silica stops the glue from running or dripping. This makes application simpler. It includes strength to the bond. The adhesive holds points together much better. Sag resistance is essential for adhesives utilized above or on walls.

Sealers benefit in a similar way. Aerosil 300 enlarges sealant formulas. It stops the sealant from plunging prior to it remedies. This guarantees a great seal. The silica enhances the treated sealer. The sealer lasts longer. It deals with activity and stress better.

5 FAQs of Aerosil 300 Silica-based Fumed Silica Evonik Hydrophilic Fumed Silica for Paint Coating HTV Silicone Rubber Adhesives Sealants

What is Aerosil 300?
Aerosil 300 is a type of fumed silica made by Evonik. It is hydrophilic. This means it attracts water. It is a very fine white powder. Fumed silica is created through a special high-temperature process. This process produces particles with unique properties.

What does Aerosil 300 do in products?
Aerosil 300 acts like a thickener. It makes liquids thicker. This is called rheology control. It prevents things from settling. Pigments stay mixed in paint. Fillers stay suspended in sealants. It also helps build structure. This improves how the material applies. It makes application smoother.

Why use Aerosil 300 instead of other thickeners?
Aerosil 300 works effectively at low amounts. You don’t need much. It provides excellent thickening power. It gives good anti-settling properties. It enhances reinforcement. This means it makes materials stronger. It improves mechanical strength. It helps silicone rubber resist tearing. Its fine particles create a large surface area. This surface area interacts strongly with the material around it.

Where is Aerosil 300 commonly used?
People use Aerosil 300 in many industries. It is popular in paint and coating formulations. It thickens paints and controls flow. It is important in High-Temperature Vulcanizing (HTV) silicone rubber. It reinforces the rubber. It makes it stronger. It is used in adhesives and sealants. It prevents sagging. It improves application properties. It helps maintain consistency.

Does Aerosil 300 offer any special benefits?
Yes. Its hydrophilic nature is key. It works well with polar systems. These systems contain water or other polar substances. It disperses effectively in these environments. It provides predictable performance. Manufacturers rely on its consistent quality. Evonik ensures this. Its particle size and surface area are tightly controlled. This control delivers reliable results batch after batch.
