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 fumed silica item made by Evonik. It is hydrophilic and works well in paint coverings, HTV silicone rubber, adhesives, and sealants. The material has a high area, around 300 m ²/ g. This helps improve thickening and support in several applications. The main bits are extremely little, about 7 nm. The bulk thickness is roughly 50 g/L. The pH worth is neutral, in between 3.7 and 4.5.

In paint and finish systems, Aerosil 300 functions as a thixotropic representative. It manages flow actions and quits drooping on upright surfaces. The silica bits create a network framework. This framework breaks under shear stress and anxiety yet reconstructs when stress and anxiety is eliminated. It makes finishes easier to apply while keeping them secure. The high pureness of Aerosil 300 makes sure no undesirable reactions in formulations.

For HTV silicone rubber, Aerosil 300 enhances mechanical stamina. It includes support without influencing transparency. The silica disperses equally in the rubber matrix. This creates far better tear resistance and solidity. Handling ends up being smoother because the powder mixes well.

In adhesives and sealers, Aerosil 300 changes viscosity and protects against settling. It provides non-sag residential properties to items like construction sealants. The silica enhances communication and resilience. It works in both solvent-based and water-based systems. The neutral pH prevents interference with treating processes.

Aerosil 300 is easy to take care of yet calls for correct dispersion. High-shear blending devices are recommended. The powder can take in dampness, so storage space in dry conditions is necessary. Safety standards consist of utilizing dust masks to avoid breathing.

The product fulfills market standards for top quality and performance. It is compatible with several materials and polymers. Applications range from industrial coatings to vehicle sealants. Customers can adjust the dose based upon wanted structure and stability. Testing small sets first is advised for ideal outcomes.

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

Aerosil 300 silica-based fumed silica from Evonik is a hydrophilic fumed silica widely utilized in commercial applications. It enhances efficiency in paint and finishing systems. The item works as a thickener. It prevents settling of pigments throughout storage space. This ensures consistent shade and appearance in the final product. The high area of Aerosil 300 improves suspension stability. It enables layers to maintain smooth application on surface areas. Repaint films get far better scratch resistance. The additive reduces drooping on vertical surfaces. This works for building and automobile finishes.

In HTV silicone rubber, Aerosil 300 serves as a strengthening filler. It increases mechanical toughness and tear resistance. The material maintains flexibility even under heats. This makes it ideal for seals and gaskets popular atmospheres. The silica boosts processability throughout blending and molding. It lowers adhering to equipment surface areas.

Adhesives take advantage of Aerosil 300’s capacity to control circulation residential or commercial properties. It adjusts viscosity without influencing bond strength. The product prevents dripping or running throughout application. Bonds continue to be long lasting under tension or exposure to wetness. The silica boosts communication in solvent-based and hot-melt adhesives. It ensures uniform circulation of ingredients.

Sealers make use of Aerosil 300 to accomplish perfect rheology. It gives sag resistance while staying simple to use. The silica boosts resistance to weathering and UV direct exposure. Treated sealers reveal much better elasticity and adhesion to substratums. It lessens contraction during drying. This avoids cracks or gaps with time.

Aerosil 300 works in both water-based and solvent-based systems. Its small fragment dimension permits even diffusion. The product is chemically inert. It does not conflict with various other solution elements. Users change dose levels to meet specific efficiency demands.

The flexibility of Aerosil 300 makes it a vital additive throughout sectors. It attends to difficulties in paint, rubber, adhesives, and sealers. Producers depend on it to boost product quality and toughness.
