Sherwin-Williams launches single-coat DTM polyurethane topcoat
Last update on Aug 27, 2025
Sherwin-Williams Protective & Marine is helping make coating applications faster and longer lasting for an array of industrial- and marine-related assets with the new Acrolon 680 single-coat topcoat. The high-performance direct-to-metal (DTM) polyurethane coating delivers notable efficiencies, reducing application time and material usage via its minimal surface preparation requirements, quick dry times and excellent one-coat coverage.
High-gloss finish & excellent color retention with low-VOC coating
The high-volume-solids coating answers fabricators’ and owners’ needs for speed, durability and aesthetics in an easy-to-apply formulation that performs in the shop and the field.
Application of Acrolon 680 is simplified and accelerated through a combination of capabilities. First, the high-solids polyurethane can be applied to marginally prepared surfaces, specifically SSPC-SP2 hand tool cleaned surfaces with tightly adherent rust. In addition, Acrolon 680 can be applied DTM in a single, high-build coat, eliminating the time required for installations of comparable multi-coat acrylic or alkyd systems. It also offers a faster return-to-service compared to acrylics or alkyds. Finally, applicators have the flexibility to apply the coating by spray, brush or roller.

“Acrolon 680 provides simplified, yet robust, protection for surfaces not prepared with advanced methods, whether you’re producing new components, equipment or structures, or you’re cleaning up your existing assets. It can be used anywhere steel needs a single-coat and long-term protection. Given its ease of application, Acrolon 680 is the premier choice for production efficiency,” said Paul Trautmann, marketing director, Infrastructure, Sherwin-Williams Protective & Marine.
Acrolon 680 delivers outstanding chemical resistance and a tougher, more durable finish than traditional acrylics and alkyds. This volatile organic compound (VOC)-compliant coating features 65% volume solids and contains less than 340 g/L VOCs, making it a high-performance solution for a wide range of industrial applications. Ideal for use on tanks, piping, valves, structural steel, marine vessels and equipment exposed to harsh chemical processing environments, Acrolon 680 provides reliable protection and long-lasting performance.
This technology meets SSPC Paint 36 standards and provides a high-gloss finish and excellent color retention to assets, ensuring a vibrant, professional appearance even under extreme ultraviolet exposure and weathering. The coating is also fully customizable to any color.
