The E-coat process is best described as a cross between plating and painting. It is a process where a metal part is immersed in a water-based epoxy paint emulsion. Electric voltage is applied to the raw metal part causing the paint emulsion to condense onto the part. The process works on the principal of "Opposites Attract".
The process begins with 9 stage cleaning and zinc phosphate pretreatment, followed by total immersion in our RoHS compliant PPG Powercron� 6000CX lead-free HAPS free black electrocoat paint. The paint particles are drawn to the raw part and the epoxy paint is deposited onto it, forming an even, continuous film over every surface, in every crevice and corner, until the coating reaches the desired thickness.
The painted parts then go through a series of 3 counter flowing water rinses and finally on to our overhead curing ovens ensuring total paint coverage uniformity on all external and recessed areas and total paint adhesion.
Advantages of E-Coat
Uniform coverage to the entire part
Contains very little water eliminating runs or sags
Minimal waste, drastically reducing material costs
At our 145,000 square foot facility we operate a programable overhead monorail e-coat paint line capable of handling parts up to 72" in length.
