Paints and coatings company PPG (Pittsburgh, Pennsylvania) introduced its Kwikspar 600 (full gloss) and Kwikspar 600SG (semi-gloss) polyaspartic coatings, designed to represent a new line of corrosion-resistant, direct-to-metal (DTM) coatings formulated with advanced film-build and fast-curing characteristics to improve efficiency.
In highly corrosive environments, both coatings can be overcoated on AMERCOAT 370 or SIGMAFAST 278 epoxy primers to provide an ultra-fast-drying alternative to three-coat systems. In low to moderately corrosive environments, one coat of either coating can replace traditional two-coat epoxy/urethane systems, the company says.
Formulated from 73% solids, the coatings cure up to eight times faster than standard polyurethane coatings in a 4-mil (25.4 µm) thickness on a low-temperature substrate. They also exhibit strong durability, flexibility, and abrasion resistance, making them ideally suited for steel building and structural components that require corrosion resistance, weathering, and gloss and color retention.
“When Kwikspar coatings are applied to steel in the shop, their ability to cure quickly accelerates production of finished parts,” says Diane Kappas, vice president of the company's protective and marine coatings business for the Americas region.
“When applied in the field for maintenance or new construction projects, they have high film build, which enables applicators to achieve a desired finish more quickly,” Kappas adds. “The coatings also can be applied directly to steel. The result is an exclusive combination of benefits that helps owners and contractors save time, labor and material cost, and return their assets to service quickly.”
