INNOVATIVE AMINE CURING AGENTS FOR EPOXY RESINS

摘要

Recent advances in new amine functional curing agents have improved performance of waterborne two-package epoxy coating systems. These new amine adducts offer performance advancements along with the ability to meet low and ultra-low VOC levels. This paper will summarize the performance of a new Zero VOC, water-soluble, amine curing agent in WB epoxy formulations with liquid epoxy resin at less than 50g/L VOC. We will review the performance of these new starting formulations versus commercially available coatings for concrete. This new waterborne curing agent is designed for cementitious applications in industrial and Do-It-Yourself (DIY) markets. Formulations based on this new amine curing agent demonstrate water reducible epoxy coatings systems with superior handling, application properties, and visible end of pot life; combined with improved resistance to chemicals and staining. A WB epoxy coating system that offers the end-user excellent performance, corrosion-resistance at less than 100 g/L VOC levels for metal protection will also be discussed. Using new amine adduct technology, these waterborne epoxy systems offer uncompromised high performance, low VOC levels and the advantages of easy water clean up.
