ABSTRACT:
An epoxy resin composition containing an imidazole curing agent is useful in processes for lining the interior surfaces of buried pipes. The imidazole is non-substituted at the 1 position and is preferably alkyl-substituted at the 2 position, such as 2-propyl imidazole. Pipe-lining compositions using such imidazole-cured systems have long working lives, short cure times at moderate temperatures, low tendency to exotherm, insensitivity to moisture, and low creep and shrinkage, resulting in a pipe-lining system which can be used in a wide range of field conditions and produces a superior pipe liner.
