Sherwin-Williams Introduces One of the First Direct-to-Metal High Solids Epoxies Approved by Army Research Lab

December 5, 2013

Sherwin-Williams announces MIL-PRF-22750G Type III, Grade A Seafoam Green High Solids Epoxy, which meets the military specification for direct-to-metal (DTM) applications. The new product is one of the first DTM high solids epoxies to earn approval from the Army Research Lab in Aberdeen, Md.
The two-component coating can be used in applications that specify either Grade A or Grade B finishes, including Army or Navy equipment requiring weather resistance or for interior surfaces. It offers superior corrosion resistance and satisfies the Army Research Lab’s stringent requirements of performance to a minimum 1,000 hours of salt spray and 40 cycles of cyclic corrosion.
“Sherwin-Williams is proud to offer a direct-to-metal high solids epoxy coating for military applications,” said Beth Ann Pearson, Global Product Manager, Military Coatings, Sherwin-Williams. “Eliminating the need for a primer coat means faster finishing throughput. We help finishers to be more efficient in their efforts to protect American military personnel.”
The MIL-PRF-22750G Type III Seafoam Green High Solids Epoxy is designed for one-coat application directly over zinc phosphate steel or treated aluminum, eliminating the need for a primer coat. A primer may be applied under the topcoat if desired. The epoxy provides excellent flow characteristics, is free of lead hazards, and offers a good combination of potlife and dry time.
