A description of the development stages of a polymer composition designed to ensure the restoration of the operational characteristics of large-diameter pipelines (d = 1100–1400 mm) using metal split sleeves, as well as for filling and sealing mixtures in the repair and construction industry, is presented. It is shown that the developed epoxy–urethane composition of a low-temperature curing adhesive paste provides a stable and safe pipeline restoration without interrupting the product transportation cycle.
