Description
Insulcast I-Gel 70 CC is a two-part silicone dielectric gel from ITW Performance Polymers that protects sensitive electronics from heat, moisture, and vibration. It cures to a soft, thermally conductive gel that carries heat away from hot-running parts while cushioning delicate components.
Insulcast I-Gel 70 CC Benefits
- Seals out moisture, dust, and airborne contaminants
- Cushions components against shock and vibration
- Carries heat away from hot-running parts (0.62 W/mK)
- Meets UL 94 V0 flame-retardant requirements
- Delivers strong dielectric protection for reliable electrical isolation
- Backed by ITW Performance Polymers quality
