Circalok™ 6744 Silicone Encapsulant Where to Buy
Product Information
Circalok™ 6744 encapsulant is a two-component silicone system for use in applications requiring a low viscosity, flame retardant encapsulating material.
Shelf Life
Shelf life of each component is six months when stored at 25°C in original, unopened container. The material must be periodically rotated within its container to maintain maximum shelf life. Settling will occur if not mixed.
Features and Benefits
Low Viscosity – maintains low viscosity for complete and void-free encapsulation.
Broad Temperature Range – can be used on parts and devices that experience operating temperatures from -55°C to +205°C.
Flame Retardant – meets UL 94 V-0 requirements.
