AkzoNobel introduces Interpon Dual Coat powder coating system to put a ‘spring’ in an automotive manufacturer’s step
AkzoNobel has launched the new generation of Dual Coat, a sustainable, zinc-free and BPA-label free powder coating system within its Interpon A1000 range dedicated to coil springs. It has been developed specifically to deliver the highest levels of protection against corrosion and everyday wear and tear for springs and other essential automotive components to advance vehicle safety.
From coil springs to stabilizer bars, this latest innovation delivers outstanding protection, ensuring vehicles remain safer and last longer on the road. By enhancing resistance to corrosion, as well as everyday wear and tear from chips and stones, it extends the lifespan of suspension springs, and reduces the risk of failure caused by challenging road conditions.
For customers, this means greater reliability and fewer maintenance costs – ultimately improving both safety and long-term value; Interpon Dual Coat reduces the frequency with which the components need to be replaced.
A key advantage of this powder coating it doesn’t contain zinc. Zinc is abrasive in nature, and removing zinc from the primer formulation results in less wear on the application equipment. This contributes to a more sustainable solution, reducing the production line’s environmental impact and the resources consumed. It enables customers to use less material due to the primer’s much lower density, optimizing the overall cost per unit coated, consequently increasing customers’ competitiveness in the market. Another key feature is that it is Bisphenol A (BPA) label free, ensuring safer handling, transport, and use across the globe.

This development also marks a major milestone for AkzoNobel in its ongoing commitment to sustainable innovation: “This is a significant achievement for the automotive coatings industry,” says Gustavo Carvalho, Automotive Key Account Management and Segment Director, AkzoNobel Powder Coatings. “Our new solution not only meets but exceeds the challenging performance standards set by the world's leading automotive manufacturers, while also providing cost efficiency gains at the coating line. It demonstrates Interpon’s ability to create products that balance exceptional performance, with the need for even greater sustainability.”
The result of more than three years of extensive research and testing, this product’s advanced corrosion resistance meets the latest industry standards and has successfully passed the stringent requirements set by one of the world’s leading spring manufacturers. This demonstrates its ability to withstand the rigorous demands of current and future automotive performance expectations.
Interpon A1000 series is a range of powder coatings designed to provide reliable protection not only against the weather, but also against fuel, battery acids, and other common challenges found in automotive applications. These coatings are widely used to protect a range of critical automotive components, including engine blocks, suspension springs, and brake systems.
