Combining aesthetics and performance in the coil-coating process

Striking gold: Henkel introduces new color variant of 
thin organic coating for metal surfaces

Düsseldorf – Henkel is expanding its portfolio in the field of thin organic Coating (TOC) with a new color variant. This innovation combines the proven properties of the technology with aesthetic benefits and is aimed at applications where both functionality and design are important – in the case of the pilot project, through a golden finish.

Thin Organic Coating is a hybrid coating system that combines passivation with organic polymers and is particularly used in the coil-coating process. It provides excellent adhesion, built-in corrosion protection, anti-fingerprint properties, and lubricity for metal strips coated with zinc, aluminum-zinc, or zinc-magnesium-aluminum. Compared to traditional passivation or primer systems, TOC allows a thinner film of 1 to 2 microns without compromising performance. This technology protects metal surfaces efficiently while optimizing material use and supporting sustainability.

Color TOC extends the capabilities of traditional TOC technologies by enabling specific colors on coil surfaces. In the pilot project, a golden variant was developed to meet the requirements of a key customer in the construction industry. This color helps differentiate and identify products, as conventional TOC coatings are clear and transparent, making brand recognition difficult. The golden-yellow shade enhances visual distinction, supports product authentication, and helps prevent counterfeiting.

The technology provides excellent corrosion protection, ensuring long-lasting performance even under extreme conditions. Its thin film enables efficient resource use, and the coating can be seamlessly integrated into existing production lines without extensive modifications. It can be applied with standard coating technologies, offering high flexibility and adaptability. In addition, its outstanding resistance to humidity and water offers long-term protection. The uniform coating not only enhances the visual appearance but also maintains consistent gloss and color stability. Unlike conventional clear TOC, Color TOC delivers consistent gloss and shade, optimizing the visual impact of the coated coils.

“Alongside the customer-specific golden shimmer variant, we have also developed prototypes in additional colors, including bright green, red, blue, and brown, based on our Color TOC product. These colors can be further customized to meet the specific requirements of our customers,” explains Dipak Chaudhari, Product Development Manager IMEA for Industrials at Henkel.
