|---|
| CONATHANE EN-7 and EN-8 are two-component, non MBOCA based, high strength liquid polyurethane resin systems designed to ensure the performance of electrical/electronic assemblies exposed to severe environmental extremes. Elastomers prepared from these systems exhibit the following outstanding properties: Superior hydrolytic stability Low viscosity Fungus resistance Exceptional dielectric properties Thermal shock resistance High strength High elongation These systems are recommended for use as molding and potting compounds for electrical cables, connectors, modules, wire wound devices, strain sensitive devices, as well as 100% solids coatings for printed circuitry. Their excellent adhesion to most substrates, and good flexibility, also suggest their use as staking and filleting adhesives.&& |
