With the ability to withstand acids, bases and many solvents, Master Bond EP62-1 is primarily used as an adhesive, sealant or coating where the epoxy will be exposed to very harsh conditions. This two part epoxy features thermal stability with a glass transition temperature exceeding 170°C.
Two component epoxy resin system featuring excellent temperature and chemical resistance
- Convenient handling, long open time at room temperature
- Cures rapidly at moderately elevated temperatures
- Superb physical strength profile
- Reliable electrical insulation properties
Master Bond EP62-1 is a two component epoxy system that has an exceptionally long working life at ambient temperatures and cures rapidly at moderately elevated temperatures. It has a very forgiving 100 to 10 mix ratio by weight. The pot life of 100 grams is greater than 12 hours. Typical cure schedules range from 4-6 hours at 140-158°F [60-70°C], 20-40 minutes at 176-212°F [80-100°C] or 10-20 minutes at 257°F [125°C]. To obtain optimum properties, post curing at 212-302°F [100-150°C] for 2-4 hours is recommended. Following an optimum cure schedule, EP62-1 has a glass transition temperature in the range of 160-165°C. Also noteworthy is its outstanding chemical resistance to acids, bases, many solvents and other chemicals, even at elevated temperatures (as listed in the table below). This system has excellent electrical insulation properties. The service temperature range is -60°F to +450°F The color of Part A is clear and Part B is dark brown in color. EP62-1 is a “go to” material for aerospace, electronic, optical, specialty OEM and related applications, particularly when high temperature resistance along with the ability to withstand aggressive chemicals is required.
