ABSTRACT:
A kit comprising materials for sealing leaks in low-pressure gas lines. The kit contains, (a) optionally, a container of corrosion-resistant primer composition; and (b) a special laminated tape comprising a ply of rubber such as neoprene and a ply of pressure-sensitive conformable polyer-based adhesive material based on, e.g., ethylene-propylene rubber, and (c) a seal restraining fabric impregnated with a curable resin such as moisture-curable polyurethane which is characterized by good shelf life and a controlled curing speed when subjected to moisture. The tape of the invention also relates to the novel protective patch structures which are formed by use of the kit material.
