SILCAST™ SC-417
- Chemical Family
- Silicones
SC-417 is a two-part, low viscosity, clear silicone which will cure at room temperature or at elevated temperatures. The cured elastomer is suited for electrical/electronic potting and encapsulating applications and provides environmental protection. It is readily pourable and can cure from room temperature to 200°C. The cured resin has a very good flexibility with excellent electrical properties and high temperature resistance.
