Cataphoresis painting is a process to increase corrosion resistance of exterior surface of the goods. It’s a electro coating process based on electrochemistry. Cataphoresis means application of paint by an electro-phoresic method, whereby Appropriate anti-corrosive basic surface treatment for powder coating colors. Cataphoresis Treatment. (Cationic Electro Deposition of Paint / Electro Coating). The process of cataphoresis is a electtro deposition of paint in.

Difference between E-Coat and Cataphoresis Process

It is feeding itself and an integrated working auxiliary plant that keeps chemical waste material under continuous control. Better surface adhision properties to have cataphoreais superior cross cut and impact test result. Please forgive any resultant repetition or failures of chronological order.

A closed chemical process to provide enviromentally friendly solution to cating. Paint solids will stick to the part as it exits the dip tank and these are removed in the rinse tank.

In Pretreatment the parts are cleaned and phosphate coated. Hanging tools are used in cataphoresis line, have no additional cleaning wastes because this tools are developed to provide to not stick the painting on themselves.

Cataphoretic paint is a known process. Cataphoresis paint is water-based paint. Hello, Thanks a lot for all your answer.

The work piece can be either cathodic in which case the coating may be called cataphoretic, cathodic electrodeposition, or CED or anodic in which case the process may be called anaphoretic.


There are no paint that loses during the painting and causes a negative working environment that are flying in the air. We added your inquiry to a thread on the subject which might clear up some of your questions. The oven cures the paint to ensure maximum performance. We use Google Analytics Cookies to monitor website traffic to help improve the website. High quality of surface treatment together with economic and environmental advantages predestined this technology to be cataphoressis in other fields of engineering and consumer goods industry.

Cataphoresis Coating – Lehmann Kataforez

We are a Brasilian company that produces surface finishing equipment, and we want to increase our product lines with this lacquers, in order to satisfy our customers. This coating is a kind of electro-chemical coating that applied wet costing to wet surface.

The issue is that subsequent coatings can only get full adhesion onto clean coatinv. I do not agree that all CED coatings are either black or white, but it is common to deposit white coatings and then apply “post-dyes” to get gold or other colors.

So can it be any paint, or does it have to be a specific one? I am investigating this process to apply to our steel and Al-alloy racing bicycles.

Is that true in every case? One of our core values is best quality.


Thanks again for your time! This experience and our chemical caaphoresis leads to meeting and even exceeding OEM minimum hours test results according to EN salt spray test. The biggest contribution to the development of cataphoresis technology has automotive industry, dataphoresis anti-corrosion resistance of bodyworks and other components is the focus of interest of all producers.


Because of its ability to coat even the most complex parts and assembled products with specific performance requirements, Cataphoresis is used by numerous industries as a means to coat products in various categories such as: It is the resin that gives the final paint treatment the anti-corrosion protection.

Products are located in the sub-region of the vehicles with no visual contact and they are described as a safety piece. Cataphoretic coating is an electrophroretic coating process when the part being coated is cathodic; anophoretic coating is an electrophoretic coating process where the part being coated is anodic.

CED coating with gold colored post dye; same part, different lighting Regular paints cannot be used because the process is not like electrostatic spraying, where the electricity is used only for attracting the paint; rather electrons coming from the cathode actually convert the paint ions to a different material.

No difference really; it’s just semantics. The paint solids are a pigment and resin component.
