Read this case study from ICL about the corrosion resistance of PUDs for bare and phosphatized steel substrates. The results from R&D team for corrosion resistance, minimal impact of gloss, improved adhesion and providing heavy metal-free anti-corrosives as an option are shown.
Know how water-based Polyurethane Dispersion (PUD) can attain a superior level of gloss and excellent adhesion to both untreated and phosphate-treated steel surfaces with the strategic adjustment of the corrosion inhibitor package.
Among the various inorganic corrosion inhibitors assessed, the heavy metal-free variant based on Dicalcium Phosphate proved to be exceptionally effective and is a preferred choice over the counterparts, emphasizing its suitability for a wide range of applications.
