CATAPHORESIS PAINT COATING IN TURKEY

CATAPHORESIS PAINT COATING IN TURKEY

Cathode Metal Coating Bath or KTL e-coating has been the essential painting process of OEM in the automotive industry.

The company is the first aftermarket manufacturer in Turkey to apply this process in-house. 

This experience and our chemical know-how lead to meeting and even exceeding OEM (minimum 720 hours) test results according to EN 50021 salt spray test.

KTL e-coating technology provides the following benefits compared to electrostatic spray paint.

A closed chemical process to provide environmentally friendly solutions to coating.

Ability to paint even the most complex geometry thanks to utilizing coating bath.

Better surface adhesion properties to have a superior cross-cut and impact test result.

Our products are described as safety parts and they are located underneath the vehicles, which causes no daily visual contact with users.

This matter plays a key role in AEC INSPECTION’s responsibility to their customers about the security and quality of the parts.

As known, chassis parts are exposed to many different forces and adverse road conditions (road salting, rain, rock hits, traction, etc.). As a result of this,

AEC INSPECTION does not only aim to produce with standardized materials and dimensions but also aims to improve the product’s life cycle and guarantee higher quality by the cataphoresis applications.

CATAPHORESIS PAINT COATING

The Cataphoresis line process consists of four main phases:
Surface cleaning phase
Surface preparation phase
Coating phase
Flash-off and oven phase
Surface Cleaning Phase

In order to link the painting with iron, surface cleaning must be done in top caliber. This phase, which consists of oil-removal and rinse tanks, removes the negative structures such as oil film, welding powders, dust, etc. from the piece.

Surface Preparation Phase

This phase exists in order to lodge the ZnPO4 crystals to the surface and to provide linkage between painting and iron. Activation tanks consist of ZNPO4 tanks and DI water-swill tanks.

Coating Phase

When the necessary preparation is completed on the metal surface, the water-based painting is applied. This phase consists of painting and UF tanks.

Flash-Off and Oven Phase

This is the phase where the liquid build-up in the paint is separated from it in the form of gas and paint is solidified after curing.

Cataphoresis Center

Chemical steams go through the SCRUBBER application. Chemical material is captured in that steam and disposed of by recycling it back to the treatment plant. The waste gas, which is cleaned in order to meet environmental standards, is released into the atmosphere.

The heat recycling is performed by the oven exhaust hood. This prevents the potentially negative environmental effects. AEC INSPECTION cataphoresis line is unique in the fact that it’s the only system among the others that has no paint sludge waste and has the self-cleaning feature.

Heat recycling is performed from the oven exhaust hood. By doing that, negative affect on the environmental factors is prevented in the cataphoresis line.

Hangers used in cataphoresis lines have no additional cleaning waste since they are developed in a way that the painting applied won’t stick on them.

This feature makes the system different compared to the other coating systems. As all the parametrical values of the bath are recorded and tracked continuously, the AEC INSPECTION cataphoresis line has no customer claims up until today.

Cross-cut and impact tests are performed on the products in order to check the quality. 18µ – 20µ painting thickness values and 720-1000 hours salt test values for corrosion are provided during this application. These test results meet the OEM values with the superior qualification.

Cataphoresis is a Water-Based Paint

This is a kind of electro-chemical coating, which is applied in liquid form. These applications deliver higher performance on corrosion and impacts when compared to electrostatic dust and electro-static wet paint coatings.

Cataphoresis lines consist of mostly closed-circuit tanks. It’s integrated and works with an auxiliary plant that can feed itself and keep chemical waste material under continuous control.

That’s why the chemical waste ratio is lower than any other application. The low amount of chemical waste and low operational cost of the system makes it much more convenient to work with and friendly to the environment.

With this process, there won’t be any flying paint particles which would create a loss of paint and inconvenience at the workstation.
