EP65HT-1 Product Description

Master Bond EP65HT 1 represents a highly innovative advance in epoxy technology in that it features the unusual combination of ultra fast cures and high temperature resistance. While typical fast setting epoxies normally possess glass transition temperatures (Tg) below 85°C, EP65HT 1 has an exceptional Tg 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 normally occurs within a few hours with exceptionally high tensile shear strengths of over 2,500 psi. This system offers good physical properties, including low shrinkage upon cure, excellent dimensional stability, high modulus and superb tensile strength. The service temperature range is 60°F to +400°F. EP65HT 1 offers superior electrical insulating properties and a strong chemical resistance profile. EP65HT 1 is qualified to meet 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 has been tremendously facilitated by the development of 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 or other volatiles. Part A is clear, and Part B is dark brown in color. It is widely used for both manufacturing and prototyping in the aerospace, electronic, computer, optical, automotive and fiber-optic industries as well as OEM applications pertaining to vacuums and clean rooms.
