This article provides an overview of the outcomes of a European‐funded project called BarrierPlus. A new type of water‐based barrier coating was developed for structural steel applications. The advantages of this coating include enhanced moisture resistance, low volatile organic compounds (VOCs) and one‐component self‐crosslinking free of isocyanates. To enable this performance, a latex polymer binder was uniquely designed without using soap‐like molecules, known as surfactants, to form the dispersion. By minimizing surfactants in the coating, the barrier properties were significantly enhanced. The latex was successfully scaled up to 15 kg quantities by an SME, coating formulations were scaled to pilot quantities and a variety of characterization and coating performance tests were completed. A life cycle assessment found that the BarrierPlus coating has a better environmental profile than an industry benchmark solvent‐borne coating and showed promising results relative to commercial waterborne benchmarks.
