The glass transition temperature for a given compound is reported as a single temperature, Tg, which represents the range of temperatures over which a cured epoxy transitions from a glassy, hard state to a more rubbery, softer state.
High glass transition epoxy compounds are of paramount importance to the selection of adhesives/sealants for elevated temperature applications. These products exhibit superior mechanical, thermal and electrical properties than lower Tg materials at high temperatures. Master Bond offers a versatile selection of high Tg materials to meet specific application requirements.
Certifications for High Tg Epoxies
Specific Master Bond one and two part systems meet the following certifications:
- USP Class VI for biocompatibility
- NASA low outgassing
- RoHS
- Halogen free
