Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
LOCTITE® EA E-60NC is a low-viscosity, two-component epoxy potting compound with an extended work life. It cures at room temperature to form a rigid, black encapsulant that is non-corrosive to metallic components. The fully cured epoxy provides excellent environmental and chemical resistance and acts as an electrical insulator.
