Protective Coatings

Sherwin-Williams Protective and Marine Coatings has launched three polyaspartic urethanes combining high throughput, superior appearance, and durability with ease of workability for applicators. EnviroLastic 840 DTM is a thin film direct-to-metal shop coating that dries to the touch in 20 minutes, eliminating grit pickup, and tolerates exposure to dew and precipitation. Its uses include high-throughput shop applications, including fracture tanks, production equipment, structural steel, rail cars, and sign structures. EnviroLastic 940 DTM is a direct-to-metal coating with gloss and color retention. The moisture-tolerant coating delivers epoxy-polyurethane performance in one coat and can be applied in temperatures as low as 35°F to production tanks and steel fabrication. EnviroLastic 980 PA is a finish coat with durability and corrosion protection. Over a zinc-rich primer, an intermediate coat is not required. The coating dries to the touch in 30 minutes, can be put into service in 2 days, and has a 3-month recoat window. It can be used for plant, refinery, and offshore equipment and piping.
