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.

Whole Silica Hydrophobic Nano Fumed Silica– Product Spec

Summary

This product is a high-purity hydrophobic nano fumed silica made from entire silica. It appears as a penalty, free-flowing white powder The material is produced through fire hydrolysis and afterwards surface-treated to come to be water-repellent. This treatment gives it solid resistance to wetness while keeping its core structure intact.

Secret Features

Hydrophobic nature: The surface area has been modified with silane-based representatives. This makes the powder fend off water effectively. It stays dry also in moist problems.
Nano fragment size: Main fragments measure in between 7 to 40 nanometers. This small dimension offers a very high surface, normally from 50 to 400 m TWO/ g.Purity: Silicon dioxide (SiO TWO) material is over 99.8%. Metal impurities are kept at really low degrees.
Flowability: The powder moves quickly and mixes well right into different systems without clumping.

Typical Applications

This hydrophobic fumed silica works well as a thickening representative, anti-settling help, or enhancing filler. It is extensively made use of in finishes, adhesives, sealants, and silicone rubber. It also improves scratch resistance in paints and aids regulate rheology in fluid systems. Because it stands up to wetness, it is perfect for exterior or high-humidity applications.

Handling and Storage

Store the product in a trendy, completely dry area. Keep containers tightly shut when not in use. Prevent exposure to dampness and direct sunshine. Use typical industrial health techniques when managing the powder. Put on gloves and eye security. Do not breathe in dirt.

Applications of Whole Silica hydrophobic nano silica fumed silica

Applications of Whole Silica Hydrophobic Nano Fumed Silica

Coatings and Paints

Entire silica hydrophobic nano fumed silica jobs well in finishings and paints. It quits liquids from taking in. This maintains surfaces completely dry and tidy. The material additionally helps paint remain smooth and not trickle when applied. It enhances scrape resistance and makes the surface last longer.

Adhesives and Sealants

This silica is utilized in adhesives and sealants to manage thickness. It quits them from moving way too much. That assists maintain adhesive or sealant right where you put it. The hydrophobic nature suggests moisture will not compromise the bond. This is essential for exterior or damp atmospheres.

Rubbers and Plastics

Including this silica to rubber or plastic makes them more powerful. It assists the materials manage anxiety much better without breaking. The water-repelling feature also secures items from moisture. That maintains efficiency stable in time, even in moist places.

Inks and Toners

In printing inks and toners, the silica stops clumping. It spreads out uniformly so shades festinate and clear. Due to the fact that it fends off water, published products withstand smudging when wet. This serves for labels, packaging, and records that face wetness.

Cosmetics

Numerous makeup and skincare products utilize this silica. It provides a soft, silky feel on the skin. It likewise controls luster by soaking up oil without drying skin. The water resistance assists makeup stay on longer, even in moist weather or throughout exercise.

Industrial Powders

Free-flowing powders require assistance staying loose. This silica layers particles so they do not stick. It works in artificial additive, pharmaceuticals, and chemicals. The hydrophobic layer blocks wetness from the air, which keeps powders stable and simple to make use of.

5 FAQs of Whole Silica hydrophobic nano silica fumed silica

What is hydrophobic nano silica fumed silica?

Hydrophobic nano silica fumed silica is a fine white powder made from silicon dioxide. It starts as regular fumed silica, then gets treated with special chemicals. This treatment makes the surface repel water. Because of this, it mixes well with oils and organic materials but not with water.

How does it work in products?

This material acts like a thickener and stabilizer. When added to liquids such as paints, adhesives, or cosmetics, it helps stop particles from sinking or separating. It also gives products a smooth texture and better flow control. Its water-repelling nature keeps moisture out, which helps extend shelf life.

Is it safe to use?

Yes, it is safe when handled correctly. It meets industry safety standards for use in many applications, including personal care and industrial products. Users should avoid breathing in the fine dust and follow basic safety steps like wearing gloves or masks during handling.

Where is it commonly used?

You’ll find it in many everyday items. It’s used in high-end coatings, sealants, and inks to improve performance. It’s also added to makeup, lotions, and sunscreens for a silky feel. Industrial users apply it in rubber, plastics, and adhesives to boost strength and stability.

How should it be stored?

Keep it in a dry, cool place inside a sealed container. Moisture can reduce its effectiveness because it’s designed to stay away from water. Make sure the packaging stays closed when not in use. Proper storage helps maintain its quality over time.
