CW-AJAerogel paste compound

Aerogel Paste and Sealant Compound

Flexible aerogel composite paste for thin-layer encapsulation, sealing, wear resistance and local thermal insulation.

Small shaped interface with a local paste application
Illustration: local paste application along a shaped interface. Not a test sample.
Product form
White paste
Thermal conductivity
0.041 W/(m·K)
AdhesionVerify method and substrate
>1 MPa

Overview

Aerogel paste and compound are intended for local thermal isolation, surface treatment, sealing and shaped interfaces where a blanket or sprayable coating is not the preferred route.

Final properties depend on the substrate, wet thickness, cure, surface preparation and any top-layer or encapsulation system.

Localized application
Evaluate at shaped interfaces and small areas where a blanket or sprayable coating is not the preferred route.
Trial on the actual substrate
Confirm surface preparation, film thickness, adhesion and cure in a representative trial.

Typical applications: Aerogel felt surface treatment, Substrate coating, Encapsulation, Vibration and heat isolation.

Product FAQ

Can it be used instead of a blanket?

It is intended for local or shaped areas; compare the thermal, mechanical and process requirements before selecting either form.

How is adhesion verified?

Run a representative adhesion and cure trial on the actual substrate using the intended surface preparation and film build.
