What is E-Coat?

The E-Coat Process

E-Coat is what the automotive industry uses to coat metal parts under the hood and under the body of vehicles to resist rust and corrosion. Look at it this way, when you open the hood of your car most everything black under there is E-Coat. E-Coat is why bodies of vehicles do not rust out like they used to prior to the 1980’s since all the car companies E-Coat grey now before the primer is applied.

E-Coat is known by many names like, Electrodeposition, Electropheretic, Electro-deposit and Elpo Dip just to name a few. Attached find the paint specifications we meet or exceed. Our intent is to be able to pass any known automotive paint specification.

Our zinc phosphate pretreatment prepares the parts for the painting process and is very robust so the paint has good adhesion and salt spray resistance.

E-Coat is a liquid paint applied electrically in a dip tank similar to a plating tank. Think of plating paint instead of metal. This electrically bonded paint is rinsed after the paint is applied to remove the excess paint giving a smooth run free surface. Unlike plating the paint is then cured in an oven that completes the cross linking of the epoxy resin giving a tough salt resistant finish.

An Advanced Coating technology that has:

  • No Lead
  • No Chrome
  • Low HAP’s (Hazardous Air Pollutants
  • Very low VOC’s (Volatile Organic Compounds or Solvents)
  • Very consistent with film build which is somewhat controllable
  • Excellent Adhesion
  • Outstanding corrosion resistance
  • Very efficient material utilization
  • Excellent coverage of complex configurations with recessed areas
  • An automated process with high production capabilities
  • Excellent appearance
  • Excellent priming qualities for top coats
  • Capability to coat a wide range of conductive surfaces
