Overview
AEROSIL 200 HV is a fumed silica additive used for rheology and thixotropy control of liquid systems, binders, and polymers. It is used as an anti-settling, thickening, and anti-sagging agent, and supports reinforcement of HTV and RTV-2K silicone rubber as well as improved free flow and anti-caking characteristics of powders. As one of the recommended international brand products in our auxiliary agent range, this additive is supplied with supply chain resource support for formulators sourcing a rheology control additive for coatings, resins, and adhesives.
Key Properties of AEROSIL 200 HV
- Rheology and thixotropy control of liquid systems, binders, and polymers
- Used as anti-settling, thickening, and anti-sagging agent
- Reinforcement of HTV and RTV-2K silicone rubber
- Improvement of free flow and anti-caking characteristics of powders
Typical Applications
AEROSIL 200 HV is used in paints and coatings, unsaturated polyester resins, laminating resins and gel coats, and adhesives and sealants, supporting formulators across marine and building and construction applications.
Why Rheology Control Matters for Coatings and Resins
Liquid coatings, gel coats, and adhesives need to resist sagging on vertical surfaces and settling during storage, while still flowing out smoothly during application. An anti-settling, thickening, and anti-sagging additive helps formulators achieve this balance, supporting a consistent film thickness on vertical or overhead surfaces and reducing the need for re-mixing settled pigments or fillers before use.
Because this additive also supports reinforcement of HTV and RTV-2K silicone rubber and improves free flow and anti-caking of powders, formulators working across multiple product platforms, such as liquid coatings and powder-based systems, can evaluate a single rheology additive across more than one formulation. Formulators should always confirm current dosage recommendations and compatibility against the latest technical data sheet for their specific formulation.
What to Consider When Sourcing AEROSIL 200 HV
When sourcing a rheology additive for coatings, resins, or adhesives, formulators typically evaluate thickening efficiency at low dosage, compatibility with the resin or binder system already in use, and consistency between production batches. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new additive for a coating, resin, or adhesive line.
Because this additive is used across such a wide range of systems, from unsaturated polyester resins and gel coats to silicone rubber and powder formulations, buyers should confirm that the grade and packaging format they are sourcing matches the dispersion equipment and process already in use on their line, rather than assuming performance is identical across all platforms.
General Handling and Storage Guidance
As with most fumed silica additives, this product should be kept in tightly sealed original containers, stored in a cool, dry location away from moisture and direct sunlight, and used within the manufacturer’s recommended shelf life. Because fumed silica can absorb ambient moisture, which can affect dispersion and thickening performance, containers should be resealed promptly after each use.
Shelf life and specific storage recommendations vary by batch and packaging format, so formulators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch of AEROSIL 200 HV they are working with.
How This Additive Compares Across Applications
Paints and coatings typically prioritize sag resistance and storage stability, while unsaturated polyester resins, laminating resins, and gel coats often place additional emphasis on thixotropic behavior during hand lay-up or spray application on vertical mold surfaces. Adhesives and sealants can add further requirements around gap-filling consistency, while silicone rubber reinforcement and powder anti-caking represent distinct, non-liquid-coating use cases for the same additive.
Because this additive is positioned across all of these applications, formulators evaluating it for a new system should confirm which performance priority, sag resistance, thixotropy during lay-up, gap-filling consistency, or anti-caking, matters most for their specific end use, and review current technical data before finalizing a formulation.
