Surface finish
Electrophoresis (e-coat) paints parts using electricity. It gives full, even coverage even in hidden areas.
What it is
Electrophoresis, or electrocoating (e-coat), is a painting method. The part is dipped in a paint bath and used as an electrode. Electric current pulls paint particles onto the surface. The coating is then baked to cure. It reaches spots that spray paint misses, like inside tubes and seams.
How it works
Pre-treat
We clean, phosphate, and rinse the part.
Dip in paint bath
The part is immersed in the e-coat bath.
Apply current
Electricity drives paint onto all surfaces.
Rinse & cure
We rinse off excess and bake to harden the film.
Why choose it
Reaches inside tubes and seams.
Seals the whole part uniformly.
Baked paint is tough and chip-resistant.
Works under a topcoat of paint or powder.

Materials
We apply Electrophoresis (E-Coat) to the materials below. Not sure if your material qualifies? Our engineers will confirm it for free.
Our solution
We e-coat steel and aluminium parts for uniform, corrosion-resistant primers. E-coat is a great base under powder or liquid topcoats.
Design tips
E-coat covers inside surfaces spray cannot.
Tell us holes to leave clear.
Add a color topcoat for appearance.
