CONATHANE EN-2523 is a two-part filled polyurethane casting system. It consists of two low viscosity liquids that have low vapor pressure and good handling properties at room temperature. CONATHANE EN-2523 can be cured at room or elevated temperatures without the formation of voids. Low exotherm, low stress build-up during cure, low shrinkage, and excellent electrical properties are other outstanding features of this system.

CONATHANE EN-2523 is recommended for potting electrical and electronic devices that are subjected to conditions of extreme thermal shock and exposure to adverse environments. The low viscosity of the system permits thorough impregnation of electrical and electronic assemblies.
