Circalok 6408 A SLW/B urethane encapsulant is a solvent-free, two-component system designed to provide a shockresistant sealant for encapsulating and potting applications.

Features and Benefits:
• Longer Working Life – Circalok 6408 SLW (slow) resin permits longer open time for processing.
• Low Viscosity – maintains low viscosity for complete and void-free encapsulation.
• Environmentally Resistant – provides excellent resistance to water and water vapor; exhibits excellent hydrolytic stability.
• Electrically Insulative – provides excellent electrical insulation properties.

Shelf Life/Storage:
Shelf life of each component is six months when stored at 25°C in original, unopened container.
If stored or shipped at cooler temperatures, Circalok 6408 B hardener may crystallize. If crystals appear, gently warm hardener at 50-60°C to melt crystals before mixing with resin.
