Latest Patents

One of Long's latest patents is titled "Controlling the hardness of electrodeposited copper coatings by variation of current profile." This innovation utilizes pulse reverse electrolysis of acid copper solutions to apply copper deposits with controlled hardness, which is essential for applications such as producing printing cylinders. The benefits of this method include improved production capacity. The hardness of the deposit is controlled by varying factors such as cathodic pulse time, anodic pulse time, cathodic pulse current density, and anodic pulse current density. Preferably, the ratio of cathodic pulse time to anodic pulse time is adjusted to achieve the desired hardness.

Another significant patent by Long is the "Non-chrome passivation process for zinc and zinc alloys." This patent discloses a non-chrome containing composition and process designed to enhance the corrosion resistance of zinc or zinc alloy surfaces. The composition includes a source of titanium ions or titanates, an oxidant, and fluorides or complex fluorides. Additionally, it may comprise an organic acid and/or a Group II metal compound, preferably a Group II metal chloride.
