Overview
Hydrophobic silica aerogel powder is intended for formulators developing low-density coatings, composites and functional fillers. The waterborne slurry route is intended where a pre-dispersed aqueous input is preferable.
Powder and slurry are different product forms. Their figures are presented separately and should not be transferred to a finished coating or composite without formulation-level verification.
- Dry powder
- Select for dispersion trials in the intended coating or composite formulation.
- Waterborne slurry
- Use the pre-dispersed aqueous form where addition order, shear and viscosity can be verified in a lab trial.
Typical applications: Waterborne industrial coatings, Thermal coating formulas, Composite fillers.

Handling and selection limits
Handling / storage
- Use dust-control and mixing procedures appropriate for fine powders.
- For slurry systems, establish shear, addition order and viscosity with a lab trial before scale-up.
Selection limits
- Not a finished insulation system or a substitute for formulation testing.
- Waterborne slurry data do not establish the performance of a customer's coating after adding binders, pigments or fillers.

Product FAQ
Can powder be added directly to a waterborne coating?
A formulation trial is required to confirm dispersion, viscosity, wetting and the final cured-coating performance.
Does the slurry figure apply to my final coating?
No. It describes the supplied slurry only; the finished coating must be evaluated in its own formulation and film build.
