Water-based coating development remains a focus for industry formulators. This push is driven by the continuing tightening of regulations brought in to lessen the detrimental impact that solvent- based coatings have on both worker health and the environment. As the technology for water-based coatings continues to evolve, one of the key challenges that remains is to significantly improve their anti-corrosion performance. In doing so, this will fully extend their use away from decorative applications into broader industrial protective coatings.
