Electrophoretic Coating

electrophoretic coating

[i‚lek·trō·fə′red·ik ′kōd·iŋ]
(metallurgy)
A surface coating on a metal deposited by electric discharge of particles from a colloidal solution.

Electrophoretic Coating

 

a coating formed on a cathode as a result of electrophoresis and coagulation of colloidal particles. The electrophoretic method of applying coatings is widely used in industry, especially in the application of paint and varnish coatings.

However, owing to its multiple disadvantages such as poor rust resistance and high maintenance costs, automakers have paved way for superlative copper and brass based automotive radiators augmented by advanced technologies such as electrophoretic coating, no-flux brazing, and laser welding methods to ensure light weightiness.
One of the concerns that have been addressed in the development of adhesives is whether they can handle the subsequent processes that bodies undergo, such as the corrosion-resisting electrophoretic coating (e-coat) process, including all of the pretreatment (e.g., degreasing, rinsing)."There are a lot of fluids that are rushing in and out of the cavities and around the vehicle assembly before the adhesive is cured," Billotto notes.
