Two Component, Epoxy Resin System Featuring Excellent Temperature and Chemical Resistance

Master Bond® Supreme 62-1 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 140-158ºF [60-70ºC], 20-40 minutes at 176-212ºF [80-100ºC] or 10-20 minutes at 257ºF [125ºC]. To obtain optimum properties, post curing at 212-302ºF [100-150ºC] for 2-4 hours is recommended. Following an optimum cure schedule, Supreme 62-1 has a glass transition temperature in the range of 155-160ºC. Also noteworthy is its outstanding chemical resistance to acids, bases, many solvents and other chemicals, even at elevated temperatures. This system has excellent electrical insulation properties. Most noteworthy is that Supreme 62-1 is a toughened system with an enhanced ability to withstand thermal cycling. The service temperature range is -60ºF to +450ºF The color of Part A is clear and Part B is dark brown in color. Supreme 62-1 is a worthy candidate for aerospace, electronic, optical, specialty OEM and related applications, particularly when high temperature resistance, a degree of toughness and the ability to withstand aggressive chemicals is required.
