Description
Insulcast I-Cast 116 FR is a flame retardant, thermally conductive two-part epoxy potting compound that protects 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.
Insulcast I-Cast 116 FR Benefits
- Seals out moisture, dust, and contaminants
- Cushions components against shock and vibration
- Moves heat away from hot-running parts at 0.65 W/mK
- Meets UL 94 V0 for fire-safety requirements
- Holds strong dielectric isolation at 420 V/mm
- Matched Part A and Part B for a repeatable 1 to 1 mix
Common Applications
- Potting power supplies, transformers, and coils
- Sealing sensors, connectors, and control modules
- Protecting LED and lighting electronics
- Encapsulating medical device electronics
- EV and e-mobility power electronics
