Abstract

Adherent gels and adherent gel composites which can be made by applying a tear resistant adherent gel of SEEPS onto one or more selected substrates of foam, plastic, fabric, metal, concrete, wood, wire screen, refractory material, glass, synthetic resin, synthetic fibers, and the like. Such adherent gels and gel composites are useful for protecting articles, the body and skin.
