  • Passes NASA low outgassing

Product Description

Master Bond EP62-1BF is a two component epoxy system that has a very long working life at room temperature and requires curing at moderately elevated temperatures. It has a very forgiving 100 to 5 mix ratio by weight. The mixed compound has a very low viscosity and good flow. The working life of 100 grams is 12-24 hours at room temperature. There are a number of cure schedule options; 6-8 hours at 140-158°F [60-70°C], 60-70 minutes at 176-212°F [80-100°C] or 20-30 minutes at 257°F [125°C]. To obtain optimum properties, post curing at 212-302°F [100-150°C] for 3-5 hours is recommended. Upon curing with the optimum schedule EP62-1BF displays robust temperature resistance with a glass transition temperature ranging from 125-130°C. It is highly resistant to many aggressive chemicals including acids, bases, solvents and other chemicals, even at elevated temperatures. EP62-1BF is a dependable electrically insulating material. The service temperature range is -60°F to +400°F. The color of Part A is clear and Part B is dark brown. It is well suited for many rigorous applications in aerospace, electronic and specialty OEM, among other industries, especially where the ability to withstand hostile chemicals is required.
