Abstract

This invention relates to a resin composition capable of being thermally cured having both a long pot life at low temperatures and a fast curing rate at higher temperatures containing a mixture of (a) a phenol-formaldehyde resole resin, and (b) a latent curing agent selected from a particular class of nitrogen-containing acidic phosphorus compounds made from either phosphoric acid or phosphorous acid.
