- Extraordinary electrical insulation properties
2. Supreme 70CN is a moderate viscosity, toughened epoxy for high-performance bonding, sealing, coating, and potting. It cures readily at ambient temperatures and more rapidly at elevated temperatures. Supreme 70CN bonds well to a wide variety of substrates including metals, ceramics and many rubbers, plastic materials, and especially composites.
An important feature is its toughness, which allows it to be used for bonding dissimilar substrates and to withstand thermal cycling.
Features
- Moderate viscosity
- Superior chemical resistance
- Black colored, optically opaque
- NASA low-outgassing
