Latest Patents
Kiyotsuka holds a patent for "CR-free paint compositions and painted metal sheets." This invention features a paint composition that includes a corrosion inhibitor prepared from porous silica particles, which are bonded with calcium ions through ion-exchange. The composition also incorporates a polyphosphate, ideally at an A/B weight ratio of 60/40 to 5/95, and an A+B ratio of 5-150 parts by weight based on 100 parts by weight of resinous components. The base metal sheet is preferably pre-treated with a chemical agent containing at least one fluoroacid. This innovative formulation ensures that the effect of calcium ions on corrosion inhibition is maintained over the long term, while also being free from harmful chromium compounds, thus posing no environmental risks.
