KTL Surface Treatment: 5 Benefits for Auto Parts Coating

KTL Surface Treatment for Automotive and Industrial Metal Parts Corrosion Protection

KTL surface treatment is an advanced electrophoretic coating process that applies a uniform, corrosion-resistant epoxy layer to metal components. Using a water-based bath and electrical deposition, parts are evenly coated on all surfaces, including edges and cavities. Widely used in automotive and engineering industries, KTL ensures long-term durability, controlled film thickness, and environmentally responsible production.

Advantages of KTL Surface Treatment

Even Film Thickness

The Electric Deposition Process produces an even layer of coating everywhere on complex shapes and inside cavities.

Excellent Protection against Corrosion

An epoxy-based coating will protect against rust and environmental elements for many years.

Efficient and Eco-Friendly Process

The transfer efficiency is high, the VOC emissions are low, less waste is discharged, and the amount of labor required is minimal.

How the KTL Process Works

The KTL coating line is run according to a controlled and multi-stage process to provide adhesion and durability:

Surface Cleaning
Oils, dirt, and other contaminants are removed from workpieces using suitable chemical cleaners; typically phosphates for steel & cast iron. Ultrasonic cleaning is used to ensure thorough removal of contaminants from intricate and complex parts.
Rinsing & Neutralization
Distilled water rinsing removes chemical residues and improves coating adhesion.
Wetting Agent Dip
Prevents bubble formation on part surfaces before immersion in the coating bath, reducing surface defects.
Electrophoretic Deposition
Parts are submerged in the KTL coating bath. Electrical current triggers a chemical reaction that deposits a uniform resin layer.
Oven Curing
The coated parts are baked to harden the film, forming a tough and glossy protective finish.

FAQ

What metals can be coated with KTL?

Steel, cast iron, and other conductive metals are suitable for KTL coatings that are commonly used in automotive (passenger vehicles) and industrial manufacturing.

Is KTL environmentally safe?

Yes. The KTL coating process uses water-based materials and has very few or no VOCs, so it generates very little hazardous waste in the process.

How thick is the KTL coating?

The film thickness of KTL coatings is closely controlled during the application process, and KTL typically creates a thin and uniform protective film or layer.

Can KTL be used for final finishes?

In many cases, KTL is used as a primer; however, in some cases KTL can also be used as a durable, standalone protective coating.
