Disclosed is a curable composition suitable for use as a coating, adhesive, or the like which comprises a storage-stable, liquid composition comprising an isocyanate-functional compound (e.g. monomer, oligomer, or polymer), an epoxy component, and an alkylating agent; and a tertiary amine catalyst precursor. Upon admixing of the liquid composition and tertiary amine, the tertiary amine forms a quaternary ammonium salt in situ for achieving cross-linking of said isocyanate-functional compound.

In situ quaternary ammonium catalyst formation for curing polymeric

Disclosed is a method for curing a film of a coating composition under vapor permeation curable conditions. Such method comprises exposing a coating composition to a vaporous tertiary amine catalyst. The coating composition can be in the form of an atomizate which is concurrently generated and mixed with a vaporous tertiary amine catalyst followed by application to a substrate, or can be an applied film of the coating composition which is exposed to the vaporous tertiary amine catalyst. The coating composition comprises a polymercapto-compound and a multi-isocyanate curing agent. The coating composition can be formulated to contain very high solids content (e.g. in excess of 70% and on up to 100% non-volatile solids).
