MasterBond's thermally conductive adhesive

Master Bond Inc. has developed a two-component, high temperature resistant, thermally conductive, epoxy adhesive, sealant and coating, called the EP21AOHT. This system has a good thermal conductivity of more than 1.44W/metre°K and adheres to a wide variety of substrates including metals, glass, ceramics and many plastics. As an adhesive, it forms high strength bonds of 5,000 psi in tensile strength, 2,000 psi in shear and over 20,000 psi in compression. This product's compressive modulus is 6,20,000 psi. EP21AOHT resists a wide range of chemicals including water, oils, fuels and some solvents over the temperature range of -50°C to 205°C.

The EP21AOHT paste features easy application with a convenient, non-critical, one to one mixing ratio and a convenient self levelling feature so it goes on evenly and smoothly.

Versatile cure schedules are available ranging from room temperature cures or fast elevated temperature cures in a short 40 minutes or starting as low as 65°C. EP21AOHT has electrical insulation properties with a dielectric strength greater than 400V/mil. It also possesses a low coefficient of thermal expansion (COE/CTE) of only 20 in/in-by-10-6/°C, low shrinkage and excellent dimensional stability. It is available in pint, quart, gallon and 5-gallon container kits.
