Cathodic Electrophoretic Clear Deposition (E-Coat) for 4H Hardness

Engineering Overview: Process breakdown of cathodic electrophoretic clear lacquer deposition on brushed brass lock cylinders, guaranteeing uniform 30um coverage.

Technical & Engineering Specifications

Hardness 4H Pencil Scratch Resistance
Thickness 25 to 35 um 100% Uniform Envelope
Salt Spray ASTM B117 > 240 Hours
Coating Method Cathodic Electrophoretic Clear Deposition (E-Coat)

Cathodic Electro-Coating Science

Traditional spray lacquer leaves thin edges where tarnish begins. Cathodic Electrophoretic Deposition (E-Coat) applies lacquer electrochemically.

100% Edge Coverage

  • Immersion Deposition: Water-borne polyurethane particles coat every sharp edge uniformly at 50–100V, providing 4H pencil hardness.
