A new single component epoxy that is not premixed and frozen, has been introduced by Master Bond with the EP17HTND-CCM. It is more convenient to handle, apply and store than typical two component glob top systems. This black, heat curable compound has a flowable paste consistency suited for glob top, chip coating and bonding applications. 

EP17HTND-CCM meets NASA low outgassing specifications and is serviceable from -62 to +316°C. This adhesive forms high strength bonds to a wide variety of similar/dissimilar substrates such as metals, ceramics, plastics, composites and various circuit board materials.

EP17HTND-CCM is thermally conductive and electrically non-conductive even upon exposure to hostile environmental conditions. EP17HTND-CCM has a high volume resistivity of more than 1015 ohm-cm at 75°F and over 1012 ohm-cm at 400°F. Its thermal conductivity is 9-10 BTU•in/ft2•hr•°F (1.4423 W/(m•K)) at 75°F. Also noteworthy is its ability to resist many chemicals including acids, bases, salts, fuels, oils and many solvents.

Formulated for various electronic applications, EP17HTND-CCM cures readily in 1-2 hours at 350°F [175°C] with a relatively low exotherm upon curing. It can be dispensed from a syringe, either manually or with an automatic dispenser. Master Bond EP17HTND-CCM is available for use in common size syringes ranging from ten to 30cc. For storage simple refrigeration at 40-45°F is recommended.

EP17HTND-CCM is a one part, heat cured epoxy that meets NASA low outgassing specifications. This high temperature resistant adhesive offers a great flow profile for glob top applications.
