Sherwin-Williams intros OneCure single-bake system
Sherwin-Williams General Industrial Coatings has introduced the OneCure portfolio, a patented dust-on-dust (DoD) powder coating system that allows primer and topcoat to cure together in a single bake.
OneCure is designed to transform finishing operations for OEMs needing speed, durability and consistency at scale. Built from multiple DoD systems proven in the field for more than 15 years, the portfolio enables manufacturers in transportation, heavy equipment and energy to streamline operational efficiency and improve coating performance while reducing energy consumption and process complexity, according to 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. There’s really no better demonstration of the portfolio’s reliability and long-term performance.”
What it does
- Uses a patented crosslinking process so primer and topcoat cure at once, enhancing intercoat adhesion
- Removes a second bake cycle and reduces material handling
- Lowers energy use and the amount of production floor and oven space required
- Improves coating uniformity and edge coverage while delivering lasting corrosion resistance
- Enables multiple primer chemistries (super-durable polyester, polyester/epoxy hybrid, epoxy and zinc-rich epoxy) to work with a single super-durable polyester topcoat
“Our customers are constantly pressured to do more with less — and OneCure enables them to do exactly that,” Reno explained. “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.
“Frankly, even if I had an extra oven, I’d switch to OneCure for the intercoat adhesion alone. The layers intertwine during co-curing, making it impossible for the topcoat to peel away from the primer, which eliminates a lot of potential issues in the field.”
Proven results
According to Sherwin-Williams, OneCure customers have seen
- 30%-40% faster cycle times vs. a traditional two-bake system
- Up to 75% fewer corrosion-related claims vs. a direct-to-metal system
- Up to 50% reduction in work-in-process inventory vs. traditional two-bake system
- Over $1 million in avoided capital expenses when building a new finishing line
- Up to 50% reduction in footprint to designated part-finishing areas
