LOW-SOLVENT PRIMER AND FINISH COATS FOR USE ON STEEL STRUCTURES. FINAL REPORT

A number of low solvent coatings designed for application to structural steel were evaluated in the laboratory. Coatings determined to provide the best performance from laboratory studies were water-borne primers based on a styrene acrylic emulsion and water-borne finish coats based on a 100% acrylic emulsion. The water-borne coatings developed in this project were applied to over seventy-five steel highway structures at various locations in California. In most cases thee water-borne coatings that were applied are providing satisfactory performance. Application of the water-borne coatings is not recommended at temperatures below 50 degree F or if the relative humidity exceeds 75%. Additional limits may be required for surface temperature of steel. New low-solvent coatings are currently being evaluated that will comply with air quality regulations and may not be as limited by weather conditions. (Author)
