Structural estimation of the curing agent component of a two-component epoxy resin.
Two-component epoxy resin cures by mixing the base agent and the hardener. Unlike one-component systems, it has the advantage of curing without the need for heating, making it widely used as adhesives, paints, and resins. In its qualitative analysis, the cured resin, which is insoluble in solvents, can primarily be evaluated for the base agent using thermal decomposition GC/MS. On the other hand, for the evaluation of the hardener, it may be necessary to measure it in its pre-cured state depending on the type. This document presents a case where a polymercaptan hardener was measured in its pre-cured solution state, and structural estimation was conducted using a combination of ionization methods (EI and FI methods).
