1. Product Overview

INSULCAST 116 FR-FC is a UL94V-0 flame-rated, two-component epoxy potting and casting compound formulated with a convenient 1:1 mix ratio by weight or volume. It cures at room temperature and is engineered for production environments, including automated dispensing. Designed for safety and ease of handling, it minimizes common epoxy-related health risks. The system provides reliable mechanical strength, electrical insulation, and thermal stability for electronic encapsulation.


2. Applications

  • Potting and casting of electronic components

  • Encapsulation for enhanced electrical insulation

  • Flame-retardant applications requiring UL94V-0 performance

  • Production line dispensing and automated mixing

  • General protection against moisture, vibration, and environmental stress
