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 solution containing a paint emulsion. An electric voltage is applied to the part causing the paint emulsion to condense onto the part. The process works on the principal of "Opposites Attract". An E-coat system applies a DC charge to a metal part immersed in a bath of oppositely charged paint particles. The paint particles are drawn to the metal part and paint is deposited on the part, forming an even, continuous film over every surface, in every crevice and corner, until the coating reaches the desired thickness.
At our 140,000 square foot facility we operate a programable overhead monorail electrocoat paint line capable of handling parts up to 23" x 23" x 72" long.
The process begins with 9 stage cleaning and zinc phosphate pretreatment. This is followed by total immersion in our RoHS compliant PPG PowercronŽ 6000CX lead free HAPS free black epoxy electrocoat paint. The parts then go through a series of 3 counter flowing water rinses and finally on to our energy saving natural gas fired overhead curing ovens ensuring total paint coverage uniformity on all recessed areas and total paint adhesion.
Advantages of E-Coat
Uniform film coverage coating on all recessed areas
The uniform coating resists corrosion
The coating contains very little water, thereby eliminating runs or sags
Waste is minimal, drastically reducing material costs
To complement our PPG PowercronŽ 6000CX E-coat lines we have two Powder Coat and two Class A Automotive Approved Oven Cured Liquid Topcoat lines:
1) A state of the art overhead conveyor with two electrostatic disc spray booths with color stacks with the ability to spray both single component high bake paints and plural component paints with catalyst activators utilizing the Graco Pro-Mix System which will cure paint in excess of 300 on parts as large as 18" x 24" x 72"
2) A floor mounted conveyor line with spray booths and unlimited color selections with the ability to cure paint in excess of 180
3) both liquid topcoat paint lines apply PPG lead free HAPS free paint
Liquid Topcoating allows us to provide a superior quality finishing coat
on top of the primed surface that will offer ultimate corrosion and chemical resistance.
The Liquid Topcoat process includes a sprayed on finish using a variety of paints and finishes that meet standard OEM specifications, Class A, and automotive exterior and interior finish qualities.
Liquid Topcoat is the final finish in the electrocoat process to fully protect your e-coated metal parts and products. Liquid Topcoat can be applied to virtually any e-coated product or material.
