Modern water-borne coating systems are being proven as effective as conventional solvent-based coatings for stopping corrosion. Their additional benefits include being evironmentally safe, tolerating minimal surface preparation and cleaning up with water.

Recent advances in acrylic resin technology have made possible improved acrylic modified cementitious coatings. They have excellent adhesion when applied on minimally prepared surfaces as primers. And, in areas where resistance to chloride ion penetration is essential and where UV degredation is a problem, these coatings also make excellent top coats.

Water-borne epoxies with acrylic modifiers have made important strides also. They are superior in corrosive environments, on submerged structures or where cathodic protection is in use. Formulations with up to 70% solids are available with long shelf-lives.

The authors will review their field experiences and research over the past 15 years with these coatings. They conclude that water-borne coating systems offer a practical, environmentally safe way of heavy industry to fight corrosion.
