A new adhesive/sealant, impregnant, and liner—EP19HT—is a storage-stable, one-component, low-viscosity system that cures readily at elevated temperatures to a tough, strong, and chemically resistant thermoset plastic. The compound’s viscosity is 500 to 600 cps at 75°F and recommended cure is 1 hr. at 250°F. Shorter cures are possible at temperatures between 325° and 350°F. EP19HT is 100% reactive, containing no solvents or diluents. It has a service operating temperature range of ?60°F to 400°F. Shrinkage upon cure is minimal. EP19HT also has excellent electrical insulation properties. It has a volume resistivity of greater than 1015 ohm•cm, a tensile strength greater than 10,000 psi, and a heat deflection temperature of more than 280°F. The clear amber compound has excellent resistance to water, inorganic acids, bases, salts, and many organic solvents. It is particularly well-suited for sealing porosity in graphite, use as an adhesive/sealant for electronic/electrical applications, and service as a chemically resistant liner.
