EP65HT-1 Product Information

Master Bond EP65HT-1 is a specialty type system that features the unusual combination of ultra fast curing and high temperature resistance. While typical fast setting epoxies normally possess glass transition temperatures (T_g) below 85°C, EP65HT-1 has an exceptional T_g of approximately 125°C. In addition, unlike typical fast cure epoxies, EP65HT-1 retains fast setup times even when mixed in relatively small masses. EP65HT-1 normally will setup in 3-5 minutes in 10-20 gram masses. A full cure generally occurs within 6-12 hours with high tensile shear strengths of over 1,200 psi. This system offers good physical properties, including low shrinkage upon cure, excellent dimensional stability and a high tensile modulus. The service temperature range is -60°F to +400°F. EP65HT-1 offers sound electrical insulating properties and a useful chemical resistance profile. EP65HT-1 fully meets the NASA low outgassing specifications and is particularly well suited for vacuum applications.

EP65HT-1 bonds well to a wide variety of substrates including metals, glass, ceramics, vulcanized rubbers and many plastics. Dispensing EP65HT-1 can be greatly facilitated by utilizing a dispensing gun capable of mixing fast setting materials with a ten to one mix ratio. This system is 100% reactive and does not contain any solvents. Part A is clear, and Part B is dark brown in color. It is especially useful for both prototyping and manufacturing in the aerospace, electronic, optical, electro-optical, vacuum related as well as specialty OEM applications where the special blend of fast curing and high temperature resistance is desirable.
