Master Bond Polymer System EP42HT-2Med is a room temperature curable two component epoxy, adhesive, sealant, coating and casting material featuring high temperature resistance along with outstanding chemical resistance. It is widely used in medical devices because of its capability of withstanding repeated sterilizations, including radiation, ethylene oxide, chemical sterilants, and steam. In addition, it fully complies with the testing requirements of USP Class VI plastics. While EP42HT-2Med is a superior adhesive, sealant and coating, it is also castable to thicknesses exceeding 2-3 inches. EP42HT-2Med cures readily at ambient or more quickly at elevated temperatures. One particularly popular cure schedule is "overnight" at room temperature followed by 2-4 hours at 150-200°F.

It has an easy to use 100:40 mix ratio by weight or 100:50 by volume. The cured epoxy compound is resistant to various types of sterilizations, inorganic and organic acids, alkalis, organic solvents and aromatic hydrocarbons. EP42HT-2Med is an excellent electrical insulator. Especially noteworthy is its serviceability from -60°F up to 450°F, combined with resistance to steam, chemicals and radiation. Aside from its widespread use in the medical industry, EP42HT-2Med is also used in electronics, electrical, fiberoptic and optical as well as OEM type applications. To optimize physical properties including heat resistance, a post cure of 100-130°C for 2-3 hours is recommended.
