Sherwin-Williams Launches Powder System to Cut Cycle Times
Sherwin-Williams General Industrial Coatings launched OneCure™, a patented dust-on-dust powder coating system that allows primer and topcoat to cure together in a single bake cycle.
The portfolio is designed for original equipment manufacturers (OEMs) that need to improve coating speed, durability and consistency while reducing process complexity. Sherwin-Williams said the system can help manufacturers streamline finishing operations by removing a second bake cycle, reducing material handling and lowering energy use.
According to the company, OneCure uses a patented crosslinking process that allows the primer and topcoat to cure at the same time, improving intercoat adhesion. The company said the technology can also improve coating uniformity and edge coverage while delivering corrosion resistance for demanding applications.
The portfolio includes multiple primer chemistries, including superdurable polyester, polyester/epoxy hybrid, epoxy and zinc-rich epoxy primers, designed to work with a single superdurable polyester topcoat. Sherwin-Williams said the portfolio is aimed at manufacturers in markets including transportation, heavy equipment and energy.

Sherwin-Williams“The portfolio is a new, unified offering, but our proprietary OneCure technology has been proven in extremely demanding, real-world production environments and used by globally recognized brands for years,” said Tommy Reno, global product director of powder, Sherwin-Williams General Industrial. “The customers we introduced to OneCure 15 years ago are still using it today. They’re not looking for other solutions because it works exactly as promised.”
Sherwin-Williams said customers using OneCure have reported 30% to 40% faster cycle times compared with a traditional two-bake system, up to 75% fewer corrosion-related claims compared with a direct-to-metal system and up to a 50% reduction in work-in-process inventory. The company also cited more than $1 million in avoided capital expenses when building a new finishing line and up to a 50% reduction in footprint for designated part-finishing areas.
“Our customers are constantly pressured to do more with less, and OneCure enables them to do exactly that,” Reno said. “If you’re building a new powder line, OneCure can significantly reduce the costs and space needed to do so. And customers who previously couldn’t justify the capital or demands of a two-bake process can now gain the added corrosion resistance of a primer system without the added complexity or costs.”
Reno added that the co-curing process improves intercoat adhesion by allowing the layers to intertwine during curing.
Sherwin-Williams General Industrial Coatings offers liquid, powder and electrocoat technologies for manufacturers and tier suppliers in markets including heavy equipment, transportation, building products, military, general finishing and design finishes. The General Industrial division is part of Sherwin-Williams Performance Coatings Group.
