MG Thermal Cond. Epoxy Encapsulating & Potting Compound 1.0 lb


Part Number: MG-832TC-450ML

Thermally Conductive Epoxy
Encapsulating & Potting Compound

100% solids. Formulated with undiluted Bis F resin for superior physical properties, and pigmented with high purity aluminum oxide pigment to provide excellent thermal conductivity at reasonable cost. Pigmented black for excellent thermal absorption and emission.

  • Provides superior protection from impact, shock, conductivity, moisture, abuse, chemicals, and analysis
  • Two part epoxy, with a 1 to 1 mixing ratio by volume.
  • Two hour working time
  • Suitable for large production runs
  • Cures in 2 days at room temperature or one hour at 65C.
