Characterization of tertiary amine and epoxy functional all-acrylic coating system

For many years the coating industry has been working on developing and/or improving non-isocyanate (NISO) coating systems to meet environmental and safety concerns without sacrificing their performance. The approach of all acrylic (AA) resins, in general comprises of anhydride/hydroxyl, tertiary-amine/epoxy, carboxy/epoxy, or activated hydrogen/ketimine functional groups. The objective of this study is to show that the functional groups in tertiary amine acrylic and epoxy acrylic resins can be determined by means of FTIR and Pyrolyzer GC/FID.

► DMAEMA homopolymer does not inject directly to PYR-GC/FID, it must be derivizated by TMAH.
► We characterizated DMAEMA and GMA monomers by using PYR-GC/FID and FTIR.
► The epoxy and tertiary-amine groups are the dominat functionalities of synthesized acrylic polymers.
