The Sherwin-Williams Company (Cleveland, Ohio) introduced Polysiloxane 1K, a single-component polysiloxane finish coat reported to provide superior weathering and chemical resistance and extended service life in harsh environments.
The product offers long-term color and gloss retention, said Brad Rossetto, vice president, marketing, Sherwin-Williams Protective & Marine Coatings. “It’s a single-component coating that eliminates the hassle of mixing that comes with two-component coatings. This means less product and packaging waste, saving time and cost,” he said.
The product is recommended for maintenance or new construction applications in the petrochemical, power generation, marine and general industrial markets. The fast-drying coating is based on a patented Sherwin-Williams resin and cures by means of reaction with atmospheric humidity. It offers low VOCs of less than 250 grams per liter, and contains no hazardous air pollutants or isocyanates, the company says.
The coating is available in an Extra White base that can be tinted, and is reported to offer protective properties in a recommended dry-film thickness range of 1.5 to 2.5 mils. Application can take place in temperatures as low as 40 F and relative humidity of up to 90%. It dries to touch within two hours at 77 F, and can be recoated within four hours, the company says.
