Abstract
An apparatus and method for protection of a substrate, e.g. an electrical contact. The apparatus comprises a support member and an encapsulant which has a cone penetration value of 100 to 350 (10.sup.-1 mm) and an ultimate elongation of at least 200%, and preferably an elastic modulus of less than 10.sup.7 dynes/cm.sup.2. The encapsulant and the substrate are pressed together so that the encapsulant is deformed into close and conforming contact with the substrate. Preferably at least part of the deformation is elastic deformation.

Apparatus for protecting a substrate, comprising:
- a gel, the gel being cured prior to coming into contact with any part of a substrate to be protected, the gel having a cone penetration value of 100 to 350 (10.sup.-1 mm) and an ultimate elongation of at least 200%;
- and
- means for deforming the gel into close and conforming contact with the substrate.
A process for protecting a substrate, comprising the steps of:
- pressing together a substrate to be protected and an apparatus comprising a support member, a gel located on the support member, the gel being cured prior to coming into contact with any part of the substrate, the gel having a cone penetration value of 100 to 350 (10.sup.-1 mm) and an ultimate elongation of at least 200%, and means for deforming the gel into close and conforming contact with the substrate, the apparatus and the substrate being pressed together so that the gel contacts the substrate and is deformed into close and conforming contact therewith.
