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.

Evonik AEROSIL ® R 202– High-Performance Hydrophobic Fumed Silica

Reliable Thickening and Thixotropy for Demanding Applications

AEROSIL ® R 202 is a hydrophobic fumed silica made by Evonik. It works well as a thickener and thixotropic agent in lots of industrial systems. This product is surface-treated with dimethyldichlorosilane, which provides it strong water-repellent buildings. Because of this, it performs accurately also in damp or damp conditions.

This silica is extensively used in epoxy materials, vinyl ester systems, gelcoats, cable television substances, adhesives, and sealants. It aids control circulation and stops drooping or settling during application and treating. The outcome is a smooth, steady mix that stays where you put it– on upright surfaces or in complicated shapes.

Easy to Distribute, Regular Outcomes

AEROSIL ® R 202 mixes conveniently into fluid systems using standard devices. It does not require unique solvents or high-shear blending in a lot of situations. Once included, it quickly constructs framework without influencing the last quality or color of the item. Customers get foreseeable viscosity and trusted anti-settling performance batch after batch.

The hydrophobic nature of R 202 also boosts storage stability. It minimizes dampness uptake in sensitive formulations, which aids extend life span and keep efficiency gradually. This is especially crucial in exterior applications or settings with temperature swings.

Constructed for Industry Standards

Produced under rigorous quality assurance, AEROSIL ® R 202 satisfies global regulative demands. It supports constant manufacturing and high-grade end products across sectors like marine, building, electronics, and compounds. Whether you are making protective coverings, architectural adhesives, or cable television insulation, this additive supplies dependable rheology control without added steps or cost.

5 FAQs of Evonik AERSIL R 202 Hydrophobic Fumed Silica Epoxy Vinyl Resin Thickener Thixotropic Agent Gelcoat Cable Adhesive Sealant

Frequently Asked Questions About Evonik AEROSIL® R 202

What is AEROSIL® R 202 used for?

AEROSIL® R 202 is a hydrophobic fumed silica. It works as a thickener and thixotropic agent. People add it to epoxy, vinyl ester resins, gelcoats, cable compounds, adhesives, and sealants. It helps these materials stay in place without sagging or dripping.

How does it improve product performance?

This silica gives strong anti-settling and anti-sag properties. It keeps fillers and pigments evenly mixed. The material stays stable during storage and application. After curing, the final product has better surface quality and mechanical strength.

Is it easy to mix into formulations?

Yes. AEROSIL® R 202 disperses well with standard mixing equipment. High-shear mixing helps get the best results. Make sure to add it slowly while mixing to avoid lumps. Proper dispersion ensures full thickening and thixotropy.

Why choose a hydrophobic grade like R 202?

Hydrophobic means water-repelling. R 202 resists moisture better than untreated silica. This makes it ideal for outdoor or humid environments. It also improves compatibility with organic systems like epoxies and vinyl esters.

Does it affect curing time or clarity?

AEROSIL® R 202 does not change the curing chemistry of most resins. It has little impact on cure speed when used at normal levels. In clear systems, it may cause slight haze. For transparent applications, test small batches first to check appearance.
