Dosages of Fumed Silica

1. Coatings and Paints

Typical dosage ranges from 1% to 10% by weight of the total formulation, depending on desired viscosity and performance.

2. Adhesives and Sealants

Dosages generally range from 0.5% to 5% by weight, tailored to achieve the desired thixotropic properties.

3. Plastics and Composites

Commonly used at levels of 1% to 5% by weight to enhance mechanical properties.

4. Pharmaceuticals

Flow agents are typically used at 0.5% to 2% by weight in powdered formulations.

5. Food Industry

Dosages often range from 0.1% to 2% by weight, depending on the specific application and desired anti-caking effect.

6. Cosmetics and Personal Care

Used at levels of 1% to 5% by weight to achieve optimal texture and stability in formulations.
