Overview
AEROSIL 200 V is a hydrophilic fumed silica used to control rheology and thixotropy in liquid systems, binders, and polymer formulations. As one of the recommended international brand products in our auxiliary agent range, this fumed silica grade is widely specified by formulators who need reliable anti-settling, thickening, and anti-sagging performance across paints, coatings, adhesives, sealants, and rubber compounds. Because it is hydrophilic, it disperses readily in polar and water-based systems as well as many organic binders, which is part of why it shows up across such a wide range of formulation types. Thousands Chemicals provides supply chain resource support for buyers sourcing this product alongside related rheology and processing additives.
Key Properties of AEROSIL 200 V
- Controls rheology and thixotropy of liquid systems, binders, and polymers
- Functions as an anti-settling, thickening, and anti-sagging agent
- Reinforces HTV-silicone rubber formulations
- Improves free-flow and anti-caking characteristics in powder systems
- Reduces dust development during handling
- Offers improved incorporation when sufficient shear force is applied during processing
Typical Applications and Industry Use
Formulators across several industries specify this fumed silica additive for its combination of rheology control and reinforcement properties. Typical applications include:
- Paints and coatings
- HTV-silicone rubber
- Adhesives and sealants
- Printing inks
- Cable compounds and cable gels
- Plant protection formulations
These applications span our Paints & Coatings and Adhesives industry categories, along with formulations used in automotive, construction, marine, and wind energy component manufacturing where anti-sagging and anti-settling performance is required during processing and storage. In coatings and sealant formulations specifically, consistent sag control on vertical surfaces and stable storage viscosity are often the deciding factors in whether a rheology additive is specified for a given system.
How AEROSIL 200 V Improves Rheology Control
Fumed silica products like this one build a three-dimensional network within a liquid system through hydrogen bonding between silanol groups on the particle surface. This network is responsible for the thixotropic behavior formulators rely on: viscosity increases at rest, which prevents pigment or filler settling and controls sagging on vertical surfaces, while viscosity temporarily decreases under shear during mixing, pumping, or application. Because the additive requires sufficient shear force for proper incorporation, formulators typically need adequate mixing energy and dispersion time to achieve full thixotropic effect, particularly in higher-viscosity binder systems. Getting the incorporation method right has a direct impact on sag resistance and anti-settling performance in the finished formulation. Formulators comparing rheology additives should also weigh dosage against target viscosity, since fumed silica grades vary in surface area and thickening efficiency, and switching grades without re-testing a formulation can shift both application viscosity and long-term storage stability.
Handling and Processing Considerations
As a fine, low-bulk-density powder, AEROSIL 200 V benefits from processing practices that manage dust generation and ensure even dispersion. Reduced dust development is one of its stated handling advantages compared with less-processed fumed silica grades, which can simplify workplace handling during formulation. Adequate shear during mixing is important for full incorporation and for realizing the product’s rheological effect; formulators should always confirm mixing equipment, dosage, and safe handling procedures against the current technical data sheet and SDS before scale-up.
