What is EDP coating?

EDP coating is short Electrophoretically Deposited Paint coating. It is a type of paint primer that is specially-designed and suited for metal parts and surfaces including iron steel, zinc, or bronze among others. EDP coating is considered a superior product when it comes to even application and resistance to corrosion. Many automobile parts for example undergo EDP coating for superior durability and primer toughness.

The best thing about EDP coating is that it can produce an even coat of metals despite the shape, size, or texture. EDP primer coatings are able to reach deep down every metal surface ensuring that the paint is spread evenly. This feature and capability is especially beneficial in the sense that the metal surface or parts that were applied with EDP coating can last much longer that those that were painted manually and those that underwent spray-painting. In both these techniques, some deep cracks and recesses may not be reached by the paint primer and this would lead to easy corrosion and rusting. EDP coating on the other hand provides uniform coating and covers all surfaces making the metal surface or parts resist corrosion even longer. When it comes to durability, EDP coating is the preferred choice by various metal-based industries like car parts manufacturing for example.

Another great thing about EDP coating is that it is environment-friendly. The chemicals used in the manufacture of this specialized primer are free from lead and therefore considered as non-toxic to the environment. In terms of pre-application procedures, EDP coating only requires standard metal surface preparation. A basic scuffing of the metal surface is all the preparation needed for EDP coating. There is no necessary or required paint stripping involved. Once EDP coating is applied it will be able to adhere to the metal surface including the deep recesses and blind spots. With EDP coating, metal parts for example will become durable and corrosion-resistant for many years even under harsh conditions.

    Hi, I appreciate your EDP information but have a little more to ask. When I went to get my classic car painted, I mentioned using Imron paint because it was used for dragsters and stuck to the metal and didn’t chip. The shop guy said pretty much all paints have surpassed that technology and adhere much better but it was the primer that was susceptible to the chipping, so better primer= less chipping. Now, how does the EDP react to impacts? Is it prone to chipping or is it comparable to a good or great primer? Should the exterior surface be sanded off to be able to apply a non-chipping primer and paint? I am a little cheesed off at the bodyshop guy as I am getting some chipping and he stated the primer and basically blamed it on the factory coating (EDP). I appreciate your answer.
