This is a two-part, smooth, dark grey paste that cures to form a hard, durable polymer that is extremely thermally conductive, yet electrically insulating. It is filled with thermally conductive ceramic powders for excellent thermal conductivity. It bonds well to metals, ceramics, glass, and most plastics used in electronic assemblies.

It has a convenient 1-to-1 mix ratio, a 45 minutes working life, and a moderate curing rate. It can be cured in 24 hours at room temperature or 90 minutes at 80 °C.

This product comes packaged in a 25 mL manual dual syringe or a 50 mL industrial, dual-cartridge for use with a dispensing gun and static mixing tips.

Dispensing Gun 8DG-50-1-1 sold seperately

Additional static mixers 8MT-25 or 8MT-50 sold separately for 8329TFM-50ML only

Applications & Usages

The 8329TFM epoxy is used for bonding heat sinks, LED’s, and other heat generating components in electronic assemblies. It is suitable for use in manufacturing operations including automatic dispensing applications. It is also useful in the maintenance, repair, and hobbyist sectors.
