Cathodic electro-coat applies a negative electrical charge to metal parts, which attracts positively charged paint particles. Cathodic coatings are high performance coatings with excellent corrosion resistance that can be formulated for exterior durability.
E-coating or electro-deposition is an advantage for corrosion protection of auto parts or other steel, aluminium and casting parts. It provides a protection against corrosion in hard to reach hidden areas. It is very efficient and uniform. Cost effective when compared to other processes.
A standard e-coating process starts with load, cleaner, water rinse, rinse conditioner, phosphate, water rinse, non-chrome sealer, deionized water, e-coating dip tank, permeate rinse 1, permeate rinse 2, water rinse 3, oven bake to cure the e-coating then unload and pack.
E-coating performs well on a variety of metal substrates, it is highly durable and provides good corrosion and salt spray resistance. Epoxy e-coating meets most automotive part specifications.
