Circalok™ 6402 Urethane Encapsulant Where to Buy
Product Information
LORD Circalok™ 6402 encapsulant is a general purpose, two-component urethane system which cures to a fl exible material ideal for use as a coating, laminating adhesive or encapsulating compound. It can also be used as an excellent adhesive for many non-polar substrates, including rubber, metal and vinyl. Circalok 6402 encapsulant is suitable for use in applications such as electrical cable encapsulation, general marine sealing and caulking, water-resistant roll coverings, waterproof fabric coatings and general purpose casting compounds.
Shelf Life
Shelf life of each component is six months from date of manufacture when stored in a dry environment at 25°C in original, unopened container.
Circalok 6402 components may crystallize during storage. If crystals appear, gently warm material to 60°C and mix carefully before use.
Features and Benefits
Low Stress – exhibits low shrinkage and stress on components as it cures.
Broad Temperature Range – can be used on parts and devices that experience operating temperatures from -70 to +100°C.
Environmentally Resistant – provides excellent hydrolytic stability; cures to an abrasion resistant coating.
