RTVS 27 is a low-viscosity, UL 94V-0 flame-retardant, general-purpose, reversion-resistant RTV silicone. It offers low-temperature flexibility, excellent electrical properties, high-temperature resistance, and can be easily removed for component replacement or repair. The material cures rapidly at elevated temperatures, making it ideal for potting and casting applications.
✅ Low Viscosity: Allows for easy flow into intricate geometries.
✅ Flame Retardant: Meets UL 94V-0 fire safety requirements.
✅ Reversion Resistant: Ensures long-term performance in harsh conditions.
✅ Good Electrical Properties: High dielectric strength and volume resistivity.
✅ Flexible & Repairable: Can be easily removed for component replacement.
🔹 Electronic Potting & Casting: Protects transformers, sensors, and circuit boards.
🔹 Aerospace & Automotive Electronics: Provides thermal and electrical insulation.
🔹 Industrial Equipment: Used in high-performance electronics and power systems.
🔹 Encapsulation Applications: Ensures reliable insulation for sensitive components.
