Two component, thermally conductive, electrically insulative epoxy system

Key Features

  • Low exotherm
  • Excellent flow properties
  • Superior dimensional stability
  • Well suited for large potting applications

Product Description

Master Bond EP29LPAOHT is a two component epoxy system featuring good thermal conductivity along with being electrically isolating. It has convenient handling with a forgiving 100 to 50 mix ratio by weight. It is a low to moderate viscosity system with excellent flow properties. It can be mixed in masses over a gallon because it generates an exceptionally low exotherm. Additionally, it has a very long open time. The recommended cure schedule is overnight at room temperature followed by 4-6 hours at 150°F to 170°F. Also noteworthy is its very low shrinkage upon curing and dimensional stability.

This epoxy bonds well to a wide variety of substrates including metals, glass, ceramics and many different plastics. EP29LPAOHT is a very good heat conductor while retaining reliable electrical insulation values. It is resistant to water, fuels and oils. It has an array of other desirable properties including a high modulus, outstanding compressive strength, and a low coefficient of thermal expansion. Both Parts A and B are off white in color. The service temperature range is -60°F to +350°F. EP29LPAOHT is ideally suited for specialty potting applications where large amounts (up to and greater than 1 gallon) of epoxy will be poured at one time.
