Abstract

The present invention provides an article having a coating comprising a first layer (2) of a fusion bond epoxy resin bonded to the article (1), a layer (4) of polyolefin such as polyethylene bonded to the first fusion bond epoxy resin (2) by a first adhesive (3), and a second layer (6) of a fusion bond epoxy resin bonded to the polyolefin (4) by a second adhesive (5). Since the second epoxy resin (6) is applied over the polyethylene layer (4) an increased thickness of the polyethylene is achievable thereby increasing the shock resistance of the housing on impact with an external body.
