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.

Product Summary: AEROSIL ® 300 Fumed Silica

AEROSIL ® 300 is a high-performance fumed silica made by Evonik. It works primarily as a thickener and anti-settling agent in liquids. This item provides strong enlarging power even at reduced use levels.

Trick Features

The material has a very high specific surface area of regarding 300 m ²/ g. This large area aids it construct strong networks inside liquid systems. As a result, it stops fragments from sinking and maintains combinations secure in time.

AEROSIL ® 300 is hydrophilic. That suggests it mixes well with water-based systems. It additionally works in numerous solvent-based formulations. You can utilize it in paints, coverings, adhesives, sealants, and printing inks.

Just how It Works

When you add AEROSIL ® 300 to a liquid, its great particles develop a loose 3D structure. This structure holds the liquid in position. The effect appears immediately as raised viscosity or gel-like actions. You can regulate the final thickness by just how much you include and how you blend it.

Excellent dispersion is essential. Usage correct mixing tools like high-speed dispersers or rotor-stators. This separates clumps and spreads out the silica evenly. Once blended well, the thickening effect remains consistent.

Handling and Storage

Shop AEROSIL ® 300 in a completely dry location. Keep the container closed tight. Dampness can trigger swellings and lower performance. Wear handwear covers and eye defense when dealing with. Stay clear of breathing in the dirt.

This product satisfies stringent high quality standards. Each set is examined to make certain regular results. Evonik makes certain every delivery does the same way in your procedure.

Because of its reliability and solid thickening capacity, AEROSIL ® 300 is a top option for formulators who need stable, top quality products.

Applications of fumed silica AEROSIL 300 (Thickener) by Evonik

Applications of Fumed Silica AEROSIL ® 300 as a Thickener

Enhancing Performance in Coatings and Paints

AEROSIL ® 300 is a high-performance fumed silica made use of commonly as a thickener. In paints and finishes, it helps control circulation and protect against pigment settling. This maintains shades constant and makes application smoother. The item additionally minimizes sagging on upright surface areas, which boosts surface quality.

Stabilizing Adhesives and Sealants

In adhesives and sealers, AEROSIL ® 300 adds framework without impacting bond toughness. It quits fillers from sinking and keeps the combination attire gradually. This guarantees trustworthy efficiency during storage and usage. The silica additionally sustains non-sag behavior, which is very important for gap-filling applications.

Improving Inks and Printing Pastes

Printing inks require stable viscosity to work well on presses. AEROSIL ® 300 offers inks the best density so they transfer easily to paper or film. It likewise prevents splitting up of elements, which aids keep shade accuracy and print clearness. Screen printing pastes gain from its anti-settling result too.

Sustaining Industrial Lubricants and Greases

Oils and lubricating oils utilize AEROSIL ® 300 to remain in place under heat or pressure. It constructs a stable network that holds oil and additives with each other. This means much less leakage and longer service life. The thickener works well even in demanding settings like automobile or machinery systems.

Maximizing Aesthetic and Personal Treatment Formulas

In creams, lotions, and make-up, AEROSIL ® 300 produces smooth textures and quits active ingredients from dividing. It provides products an abundant feel without being greasy. Due to the fact that it is pure and great, it blends easily and remains unnoticeable on the skin.

Handling and Compatibility

AEROSIL ® 300 blends well right into many systems. It works in both polar and non-polar fluids. Proper dispersion is key– making use of high-shear blending makes certain full activation. When included, it supplies constant thickening with reduced usage levels.

5 FAQs of fumed silica AEROSIL 300 (Thickener) by Evonik

Frequently Asked Questions About AEROSIL® 300 Fumed Silica

What is AEROSIL® 300 used for?

AEROSIL® 300 is a fumed silica product made by Evonik. It works as a thickener and anti-settling agent. People add it to paints, adhesives, sealants, and coatings. It helps control flow and keeps solid particles from sinking.

How does AEROSIL® 300 thicken liquids?

The silica particles form a loose network inside the liquid. This network gives the liquid more structure. As a result, the liquid becomes thicker and holds its shape better. The effect happens even with small amounts of AEROSIL® 300.

Is AEROSIL® 300 safe to handle?

Yes, but you must follow safety guidelines. Wear gloves, eye protection, and a mask when handling the powder. Avoid breathing in the dust. Store it in a dry place with the container closed tight. Always check the safety data sheet before use.

Can I use AEROSIL® 300 in water-based systems?

AEROSIL® 300 is hydrophilic, so it works in water-based products. However, good mixing is key. Use high-shear mixing to break up clumps and get full thickening. Without proper dispersion, the results may be uneven.

How much AEROSIL® 300 should I add?

The right amount depends on your product and what you want to achieve. Most applications use between 1% and 5% by weight. Start with a low dose and test the results. You can adjust the amount based on viscosity and stability needs. Always mix thoroughly after each addition.
