This thermally conductive adhesive epoxy 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 and a 4 hours working life. With this long work life, the mixed adhesive can essentially Act like a one-part adhesive for the duration of a work shift. Unlike one-part adhesives, however, it does not require high curing temperatures or frozen storage, and it has a very long shelf life. 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. Applications & usages this thermally conductive adhesive epoxy is used for bonding heat sinks, LED, 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 maintenance, repair, and hobbyist sectors. Use it when a flow able adhesive with excellent thermal conductivity and a long working life is required.
