Biesterfeld and CORTEC CORPORATION agree on Europe-wide distribution of anti-corrosion additives

With immediate effect, Biesterfeld Spezialchemie is taking on responsibility for the Europe-wide distribution of anti-corrosion additives for paints and varnishes from U.S. manufacturer CORTEC CORPORATION. This cooperation is an excellent addition to the distributor’s portfolio for this industry.

The organic and inorganic corrosion inhibitors offered are suitable for both solvent-containing and water-based formulations with an acrylate, polyurethane, epoxy or alkyd basis. Used alone or in combination with conventional anti-corrosion pigments, they offer long-term protection against corrosion on ferrous and non-ferrous substrates and prevent flash-rust formation.

In contrast to conventional anti-corrosion protection based on pigments, nano-VpCI®molecules penetrate deep into all cavities on the metal surface to inhibit the corrosion process. Even at very low concentrations (< 2 %) and with a small layer thickness (25 µm), this enables the metal to withstand a salt spray test for 1,000 hours without a problem.

“We’re delighted about the new partnership with CORTEC CORPORATION,” says Kathrin Schmitt, Product Manager, Biesterfeld Spezialchemie. “The anti-corrosion additives ideally complement our product portfolio, rounding off our range for paint and varnish applications.”

Based in St. Paul, MN, Cortec Corporation is the world’s largest producer of VCI technology with multiple manufacturing locations, warehouses and laboratories. More information on the company can be found at and
