One of the primary needs in epoxy-based coatings are low-VOC systems that are able to achieve the performance of traditional solventborne epoxy/polyamides while having significantly lower applied cost than alternative solid epoxy resin-based waterborne systems.
Since the 1950s, epoxy primers and midcoats for protective and civil engineering coatings have been primarily solventborne. These systems have provided excellent performance for over six decades. In order to address the issues of solvent emissions from these systems, avoid flammability and improve worker safety, high-performance waterborne epoxies have grown significantly in the epoxy coatings market.
