This thermal adhesive is a 2-part 1-1 epoxy system. It is a smooth, dark, off-grey paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. It meets UL 94V-0 Standard as a flame retardant. It bonds well to metals, ceramics, glass, and most plastics used in electronic assemblies. This thermal adhesive is most often used to bond heatsinks to CPUs, LEDs, and other electronic components, but is also suitable in many other applications that require a thermally conductive electrically insulating adhesive. This product is viscous, yet flowable enough to dispense from a syringe. The 50ml size may be used with a mixing tip when dispensed with a caulking gun or pressurized system.
