Master Bond EP65 is a specialty type system that features the unusual combination of fast curing and good temperature resistance. While typical fast setting epoxies usually possess glass transition temperatures (Tg) below 70°C, EP65 has a higher Tg of 100-110°C. In addition, EP65 retains faster setup times even when mixed in relatively small masses. EP65 will typically will setup in 10-12 minutes in 20 gram masses. A full cure generally occurs within 12-24 hours with lap 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 +300°F. EP65 is a reliable electrical insulator and resists most common chemicals.
EP65 bonds well to a wide variety of substrates including metals, glass, ceramics, vulcanized rubbers and many plastics. Dispensing EP65 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 good temperature resistance is desirable.
