This is a two-part, smooth, off white paste that cures to form a hard, durable polymer that is extremely thermally conductive, yet electrically insulating. It is extremely viscous because it is highly filled with thermally conductive ceramic powders for maximum thermal conductivity. It adheres strongly to metals, glass, and it adheres well to most plastics used in electronic assemblies.

It has a convenient 1-to-1 mix ratio, a short 4 minutes working life, and a rapid curing rate. For a 1.0 mL sample, a minimal service cure can be achieved in 15 minutes at room temperature, and a full cure in 3 hours. It is also flame retardant, meeting the UL 94V-0 specifications.

It is available in a 50 mL industrial, dual-cartridge for use with our 8DG-50-1-1 dispensing gun (static mixer not available) or a pneumatic dispenser. 

Applications & Usages

This product is designed to bond heat sinks, LED’s, and other heat generating components in electronic assemblies. It is suitable for the manufacturing, repair, and hobbyist sectors. Use it when a thixotropic adhesive paste with maximum thermal conductivity and an extremely fast cure time is required. For automatic dispensing applications, use the 8329TFF, which offers a lower viscosity at the cost of slightly lower thermal conductivity.
