=Master Bond Polymer System EP19HT is a storage stable one component liquid epoxy resin system for durable, high performance adhesive/sealants, impregnants and liners. It features excellent storage characteristics at ambient temperatures yet cures readily at elevated temperatures to a tough, strong and chemically resistant thermoset plastic. Low viscosity facilitates handling at ambient temperatures and is particularly desirable for impregnation applications. Master Bond EP19HT is 100% reactive and does not contain any solvents or diluents therefore shrinkage upon cure is minimal. The recommended cure schedule is 1 hour @ 250°F, for best results postcure 1 additional hour @ 300°F. Shorter cure times can be achieved at temperatures between 325-350°F. The cured material has high physical strength properties (tensile strength more than 10,000 psi), is thermally stable (heat deflection temperature more than 280°F) and has superior electrical insulation properties (volume resistivity greater than 1015 ohm cm) as well as remarkably good chemical resistant properties.
