Thermal Adhesives


Adhesives offer excellent heat transfer and high voltage isolation. Epoxy adhesives offer low shrinkage, and coefficients of thermal expansion comparable to copper or aluminum. They bond readily to metals, glass, ceramics, and most plastics.

MSDS Safety Sheet for Ther-O-Bond 1500 Hardener
Ther-O-Bond 1500 is a versatile epoxy casting system developed for high performance, production potting and encapsulating applications where low shrinkage and rapid air evacuation are required. This formulation has a very low surface tension and a flowable viscosity, which affords excellent air release. Ther-O-Bond 1500 adhers to rigid plastics and laminates, metals and ceramics, has a low coefficient of thermal expansion and is readily machined and shaped with ordinary shop tools. The fully cured epoxy system is an excellent electrical insulator which provides good resistance to electrolysis, leakage and corrosion room water, weather, gases and chemical compounds.

MSDS Safety Sheet for Ther-O-Bond 1600 Hardener in PDF format
For smaller applications, Ther-O-Bond 1600 produces a stable, durable, high-impact bond, with good heat transfer characteristics. It is a thixotropic (smooth paste) thermally conductive epoxy system used for staking thermistors, diodes, resistors, integrated circuits and other heat sensitive components to printed circuit boards. This two-part adhesive develops strong, durable, high impact bonds at room temperature, which improve heat transfer while maintaining electrical insulation. Therobond 1600 bonds readily to itself, to metals, silica, steatie, alumina, sapphire and other ceramics, glass, plastics and many other materials because its coefficient of thermal expansion provides a good match for those materials over a fairly wide temperature range.

Thermalbond™

Thermalbond™ is a thermally conductive, high strength epoxy adhesive. It provides exceptional adhesion to copper, aluminum, steel, glass, ceramics, and most plastics. Thermalbond also has a coefficient of thermal expansion compatible with aluminum, copper, and brass, making it particularly well suited for thermally bonding semiconductors and other components to chassis or heat sinks.


Mixing Instructions:
Mix resin thoroughly before removing material. Add 7.1 parts of RT-7 hardner to 100 parts of resin by weight, or 17 parts of RT-7hardener to 100 parts of resin by volume. Adhesive will set up in:
24 hrs at 25°C (77°F)       1 hr. at 100C (212°F)
2 hrs. at 65°C (149°F)       30min. at 130°C (266°F)

Note: For maximum electrical and physical properties, a post cure is neccessary. Post cure at room temperature for 4 days or for 4 hours at 93°C (200°F).
