Biobased Epoxy Amine Primers for Corrosion Protection of Steel & Aluminum Alloys

Abstract The development of environmentally friendly cure chemistries which can be used to make polymers is a major area of focus in the polymer industry [1]. One area of particular interest to the DoD and Army Corps of Engineers is the development of biobased epoxies and amines which can be used as an alternative to petrochemical based building blocks to make biobased epoxy-amine coatings for the corrosion protection of various substrates. In this presentation, the corrosion performance of epoxy-amine primers under development is assessed by a combination of electrochemical measurements and accelerated corrosion tests and benchmarked against petrochemical based coating technologies. Among different biobased technologies tested, epoxy cured with biobased amine (difuran diamine) showed good performance in both corrosion testing and electrochemical measurements.
