E-coating ABC's

Electro-deposition or e-coat is an organic finishing process that uniformly applies thin-film primers and one-coat finishes to metallic substrates. E-coat resembles electroplating in that it utilizes an electric current to deposit a coating onto substrates. However, E-coat deposits waterborne paint onto substrates rather than metal ions. The overall process consists of four main process steps: pre-treating, coating, rinsing, and baking.

 

Substrate surfaces are prepared for E-coat by cleaning, phosphate coating, sealing, and reverse osmosis (RO) water rinsing. During E-coating, an electrical charge (direct current or DC) is applied to the racking fixture during immersion in a waterborne paint bath. During this process, the part becomes the cathode and there are a number of anodes spaced evenly throughout the tank. Paint molecules then travel to the substrate and adhere to the surface. Adequate bath agitation is necessary during the process to prevent bath separation and to ensure a uniform concentration of bath constituents. Coating thickness can be controlled, and is dependent on immersion time, bath temperature, process voltage, and bath chemistry.

 

After the coating process is complete, excess paint is removed from the substrate by spraying the part with a permeate rinse (consisting of the ultra-filter permeate of the e-coat bath itself) and then a RO water rinse. The rinse is collected and separated to recover paint and recycle a portion of it back to the E-coat bath.

 

After the coated substrates have been rinsed, they are then baked to cure and cross-link the coating. Baking is performed with a gas-heated convection oven. Baking temperatures are determined by time at temperature but generally fall between 350 to 370°F.

 

Because of the uniformity of the applied coating, and excellent adhesion properties, the corrosion protection offered by e-coat systems is extremely high on steel and other ferrous substrates. E-coat applies a uniform coating of pre-determined thickness over parts with simple or complex geometries and eliminates runs and sags common with conventional dip or spray applications.
