Creative Materials F947A/B-187

F-947 is a black, flame-out, two component, epoxy potting and encapsulating compound. Product is designed to release entrapped air rapidly during cure, resulting in a smooth, pinhole free surface. When used with curing agent B-187, cured product retains mechanical and electrical properties at operating temperatures up to 155°C.

Features

  • Excellent heat resistance
  • Extended pot life.
  • Requires mild heat cure.

    Mixing Instructions

    Premix Part A in original container prior to adding curing agent. Add Part B187 to Part A and mix until uniform. NOTE: It is not unusual for crystallization of the B-187 to occur. Warm to 40-45°C in a water bath to return the material to it's original viscosity. The crystallization of the catalyst does not effect the performance of the product in any way. To prevent recrystallization, store the B-187 at temperatures between 35-45°C.
