EP46HT-1ND-2 Product Information

Master Bond EP46HT-1ND-2 is a two part epoxy system for high performance structural bonding and sealing, suitable for applications where resistance to temperatures from -100°F to +600°F is required. It is 100% reactive and does not contain any solvents or diluents. While it does not cure at room temperature, it does cure readily at elevated temperatures. A good curing schedule to optimize properties is 2 hours at 300°F, followed by a few hours at 350-400°F. The cured epoxy produces bonds and seals with high mechanical strength and excellent chemical resistance. EP46HT-1ND-2 has a forgiving 100 to 30 mix ratio by weight. It should be noted that EP46HT-1ND-2 is relatively exothermic and should not be cured in sections greater than 10-20 thousandths of an inch thick and a bondline thickness is typically 2-6 thousandths of an inch. EP46HT-1ND-2 has a paste consistency and will not flow when applied or during curing.

EP46HT-1ND-2 can withstand intense thermal cycling and resist many chemicals, including water, oils, solvents, bases and acids. It bonds exceptionally well to metals, composites, glass, ceramics and many plastics. Once cured, the system is a top flight electrical insulator. The color of Part A is tan and Part B is moderately dark brown. EP46HT-1ND-2 is normally used in demanding applications found in the aerospace, electronic and specialty OEM industries where exceptional thermal and chemical resistance along with the non-drip application feature might be required.
