CONATHANE EN-14, or EN-14 Black, is a two-component, unfilled, low viscosity, fast-gelling, fast-curing, flexible polyurethane elastomer system designed for potting and encapsulation of electrical and electronic assemblies. CONATHANE EN-14 is a non-mercury version of CONATHANE® DPEN 8536. The cured system features excellent water resistance, thermal shock resistance, and electrical properties.

The initial low viscosity of the system allows good penetration into fine windings. CONATHANE EN-14 is fully transparent and can easily be cut to remove defective components. Repairs can be made by application of more of the liquid system.

CONATHANE EN-14 is particularly recommended for potting and encapsulating strain and heat sensitive devices in modules, connectors, and units required to operate in the temperature range of -65°C to 130°C. It also has shown utility as a conformal coating and can be applied by casting, spraying, or brushing. Airless spray equipment can be used effectively.
