Product Description
ARALDITE® CW 1302 GB is a highly filled epoxy casting resin designed for electrical insulation and encapsulation applications. When used within its recommended casting resin system, it can be processed and cured at room temperature or moderately elevated temperatures. The material offers good thermal conductivity, low water absorption, long-term thermal resistance, and UL 94 V-0 flammability performance at 3.2 mm thickness. It is suitable for the manufacture of inductive components, wound capacitors, and electrical devices operating in potentially explosive environments while providing reliable dielectric and mechanical performance in demanding electrical insulation applications.
Key features
- Electrical insulation performance: High volume resistivity, dielectric strength of 15 kV/mm, and CTI greater than 600 support demanding electrical insulation applications.
- Thermally conductive filled system: Thermal conductivity of 0.83 W/m·K and a Relative Temperature Index of 181°C support thermal management and long-term service performance.
- Flame-retardant formulation: Achieves UL 94 V-0 classification at 3.2 mm and complies with EN 50014 and EN 50028 requirements.
Applications / Suitable for
- Inductive components
- Wound capacitors
- Electrical insulation castings
- Electrical devices operating in potentially explosive environments
- Encapsulation and protection of electrical assemblies
