Material Notes:

Master Bond Polymer System EP46HT-2 is a two component epoxy system for bonding, sealing and casting applications where resistance to temperatures from -100°F to +500°F is required. It is 100% reactive and does not contain any solvents or diluents. It is formulated to cure rapidly and requires a cure temperature of 250°F or more. The glass transition temperature is extremely high, exceeding 220°C. The cured system features exceptional physical and mechanical properties, while exhibiting superior chemical resistance.
