Polyester polyurethane enamel delivers corrosion resistance over primers, metals

PPG Industries’ industrial coatings business has introduced SPECTRACRON® 380 POLY-IOTHANE® HS (high-solids) series coatings. The two-component polyester polyurethane enamel coatings provide corrosion resistance when applied directly to metal or over primer-coated metal surfaces.

The coatings can be used for such applications as hydraulic pumps, truck and trailer frames, water and gas meters, agricultural and construction equipment, and metal framing assemblies for commercial rooftop HVAC units.

The products can be applied over cleaned and blasted steel or top-coated over surfaces that have not been sanded or abraded. They also can be used as clear coats to protect steel from oxidation before fabrication, which can preclude the need for phosphates and other chemical cleaners as metal goes through milling, stamping, and coating.

A variety of glosses and standard and custom colors are available, including metallic and clear-coat finishes. They withstand exposure to chemicals, abrasion, and impact. The coatings can be applied using most conventional spray equipment, including air, airless, air-assisted, and electrostatic tools.
