Abstract
In a well treating process for consolidating a mass of particles with an epoxy resin precipitated from a resin-forming solution, a significant improvement is provided by using: a polyamino curing agent, a particular ratio of curing agent to epoxide, and a pretreatment which wets the particles with an aqueous liquid that contains an effective proportion of a dimethylaminomethyl-substituted phenol.
