This document describes the features and specifications of an epoxy coating called EP21ARLV. It has superior acid resistance and was tested in several acids for over 14 months with no failures. It is a low viscosity, two component epoxy that is ideal for small potting and encapsulation applications. It provides reliable electrical insulation and bonds well to many substrates including composites, plastics, ceramics, metals and rubbers.
