ABSTRACT:
There is provided an adhesive composition for use as an adhesive agent for bonding a flexible lining tube on to the internal surface of an existing old pipe. Such an adhesive composition comprises: a) an epoxy resin; b) a thixotropy agent mainly containing silica fine particles; c) a lubricant mainly containing spheroidal fine particles; d) a curing agent having a sufficient compatibility with the thixotropy agent, and being used in a sufficient amount to cure the epoxy resin. In particular, the above components a),b),c) together form a main agent, and the above components b) and d) together form an auxiliary agent. Before use, the main agent and the auxiliary agent are separated from each other. When in use, the main agent and the auxiliary agent are mixed together, so as to form the adhesive composition for use as an adhesive agent for bonding a flexible lining tube on to the internal surface of the existing old pipe.
