Insulcast I-Cast 116 FRFC Epoxy Potting Compound

Insulcast I-Cast 116 FRFC is a epoxy potting compound that protects your electronics from heat, moisture, and vibration. Pour or pump it around the assembly and it cures to a tough, protective mass that keeps the finished part working in the field. Sold in multiple sizes and, where the system is two-part, in matched Part A and Part B.
