KTL Coating – Durable Corrosion Protection, Uniform Coverage and Reliable Quality

Looking for a surface treatment that protects your components against corrosion over the long term while delivering a uniform, high-quality finish?

KTL coating, also known as electrocoat or electrophoretic coating (E-coat), is an advanced surface treatment technology widely used in industrial applications. It is particularly suitable when high corrosion resistance, uniform coating coverage and consistent, reproducible quality are essential.

During the process, the component is immersed in a water-based coating bath. An electric field causes the coating material to deposit evenly on the metal surface. This makes it possible to achieve effective coverage even on complex geometries and hard-to-reach areas.

Why Choose KTL Coating?

One of the key advantages of KTL coating is that it protects more than just the visible surfaces. The electrophoretic deposition process is well suited to components with complex shapes, flanges, recesses and hollow sections.

The finished coating offers:

High corrosion resistance
Good resistance to chemicals
Resistance to mechanical stress
A uniform, attractive finish
An excellent base for subsequent coating processes

When long-term corrosion protection is critical, KTL coating can provide a reliable and well-controlled solution.

It is an ideal choice for industrial components, automotive parts, agricultural machinery and construction equipment, as well as other metal components requiring a high level of corrosion protection with a relatively thin coating and cost-effective processing.

Which Components Can Be KTL Coated?

The KTL process is primarily suitable for electrically conductive metal components, including:

Steel and galvanised steel components
Cast iron components
Aluminium components
Copper and brass components
Zinc and magnesium die-cast components

The process is particularly beneficial for parts with complex geometries, high corrosion exposure or additional coating layers, where enhanced surface protection is required.

Uniform Coating and Controlled Process Quality

Achieving a reliable KTL coating starts with thorough pretreatment carried out under controlled conditions.

Before coating, the components undergo a multi-stage pretreatment process involving:

Degreasing
Rinsing
Surface treatment to improve coating adhesion

These stages are carried out using specialised chemicals developed for industrial applications.

We regularly measure and document the parameters of our process baths in our own laboratory. This allows us to monitor the process continuously and maintain consistent coating quality.

You receive more than a coating service: you benefit from a surface treatment process based on controlled technology and documented procedures.

The suitability of individual components should always be assessed based on their dimensions, geometry, base material and required technical specifications.

KTL coating can be used not only as a standalone corrosion protection system.

It is also highly effective as part of a duplex coating system, for example when applied over an electroplated zinc layer, or as a primer beneath powder coating or solvent-based paint systems.

This allows the surface protection to be tailored to the component's intended operating environment and technical requirements.

A More Environmentally Considerate Process

KTL coating uses a water-based coating bath in which water serves as the primary carrier medium, reducing the need for organic solvents compared with many conventional coating systems.

Our own wastewater treatment equipment supports the management of process-related chemicals and ensures that process wastewater is treated and chemicals are neutralised in accordance with applicable environmental requirements.

Quality Management

At Nagyfény Kft., quality is an integral part of the entire coating process. From receiving the components and preparing their surfaces to applying the coating and inspecting the finished parts, we work to consistently meet defined process specifications and customer requirements.

Our operations are carried out in line with the requirements of ISO 9001 and ISO 14001, with particular attention to quality management and environmentally responsible operations.

Controlled workflows and inspections help us maintain consistent, reliable and repeatable quality. We address any deviations and continuously improve our processes so that our partners can rely on predictable results over the long term.
