Kolmer Top Coating

The electric motor that doesn't peel or rust.
Extends the lifespan of the motor
by a factor of 4.
What are KTC motors? The research Four challenges Durable For your industry

The battle with the elements

Iron rusts and aluminium oxidises. Outside attacks damage the electric motor's layer of enamel paint. The result; flaking paint and corrosion. We, however, are going to battle the elements! Four and a half years of research proves that, no matter how extreme the situation, electric motors with Kolmer Top Coating (KTC) are winning the battle.

  • Lifespan quadrupled
  • Sustainable production, sustainable in use
  • Cost saving
  • Tested under extreme conditions for a long time.
  • Certified
  • Available from now on

What are KTC motors?

A motor that doesn't flake nor rust, that was our goal when we started an extensive research project in 2016. We developed a coating that does hold and the test results exceeded all expectations. Motors keep looking great year after year, no matter the conditions. TNO has tested the safety and production is now in full swing. Kolmer Top Coating anchors itself through the paint layer in the underlying aluminium and cast iron. A watery, super strong layer that protects for years on end and can be used on all our Cantoni and a selection of EMK and Cemp motors.

The research. 120 days in salt water

Two apparently identical Kolmer electric motors, 120 days in the water of the Rotterdam port. One untreated, the other provided with the Kolmer Top Coating. Take a look at the result. What is your conclusion?

Welke elektromotor ik ook koop, er voldoet geen één. Bij elke motor laat de deklaag los

Vier uitdagingen

Salt water & iron? A very bad combination!

A fishing boat, harbour crane or other place close to the sea. Anyone who works in such a place knows that salt and machines are not a good combination. Waves and the constant moist salty air will soon turn your shiny motor into a brown pile of rust. The solution? Adding another layer of paint. Slowly the cooling fins of the motor clog up so that it overheats.


“I don't want a rusty mess on board.”

Fortunately, we can offer you the best solution to the rust problem. Kolmer Top Coating extends the life of the enamel paint by a factor of four. We exposed our motors to salt water at various test locations. Three hundred days in the port of Rotterdam provided the ultimate proof; one cool motor versus algae, seaweed, rust and deposits. Our coating anchors itself through the paint layer in the underlying aluminium and cast iron. The watery and super strong layer (stronger than C3 or M5 coating!) protects the motor for years against the harmful effects of salt water.

A piece of flaked enamel amongst the fish?

Cleaning is essential in locations where food is processed. However, the moist vapours, high-pressure cleaner and detergents are disastrous for the electric motor that keeps the conveyor belt running. As detergent penetrates the skin of the paint corrosion spreads. Hey, says the Food and Consumer Product Safety Authority, your foodstuffs should not show one speck of paint! The solution; shut down your production line every six months and install a new motor. Or, purchase an expensive stainless steel motor (without cooling).


Safe, durable and reliable

There is, however, another option. At one of our customers, droplets of acid occasionally fell on the motor. The result; a replaced motor every two months. The KTC test motor has been running for eighteen months now without a trace of corrosion! All painted up, no matter how much lye, soap or other chemicals you use. The coating penetrates through the paint layer into the underlying metal where it adheres. No blisters and flakes, but rather an affordable motor that functions optimally for years.

-40°C tunnel freezer scraps your motor

Cold store? Cold tunnel? Fans blow cold air across the area. However, temperatures of -40°C are disastrous for the electric motors that power them. Due to the extreme cold, the paint of the motor cracks and everyone knows the result; rust. Do you want a great motor that will last longer than a year? You'll have to paint it time and time again and shut down your primary process to let the cold tunnel warm up before carrying out any repairs. Anyone who works with refrigeration knows that a motor that runs as long as possible without maintenance is worth its weight in gold.


Three-year warranty

Testing Kolmer Top Coating in a tunnel freezer was therefore high on our list of priorities. And the results are beyond expectations! The four KTC motors have been providing optimal cold air movement for two and a half years now. For this location in particular nearly three times the usual lifespan. Kolmer Top Coating adheres through the enamel paint layer to the underlying iron or aluminium of the motor. Rock-hard and smooth as glass. Nothing sticks to it nor penetrates it. Even in these extreme circumstances, we give a three-year warranty on our coating!

Motors placed outside on a platform

Pumping stations and pumps; in the Netherlands you will find electric motors in the open air everywhere. Wind, rain, snow or heat waves; continuously exposed to the elements. The only protection is a fragile layer of paint, which can be damaged and subsequently ends up in the environment. A rusting motor that will eventually break down.


KTC motors are therefore a wonderful, sustainable choice for water boards, municipalities and other managers of rural areas. The life of the paint is extended by at least a factor of four, making the motor last that much longer.


Thorough test phase

Salt water, acid, lye, manure and freezing temperatures. We monitored KTC motors at twenty-five test locations. The coating was specially developed for Kolmer in a German laboratory and extensively tested. Potential safety risks have been investigated in collaboration with TNO and by now the coating has been approved on all fronts. The result; sustainable, durable, safe and affordable all-weather electric motors!

Our vision on sustainability: taking the extra step

Kolmer Electric Motors are highly economic in use as saving energy is essential. We take it a bit further though. In order to produce a motor, precious raw materials such as iron and copper are melted and processed. By replacing too quickly, we don't only waste valuable production energy but precious raw materials as well. Kolmer Top Coating extends the life of a motor by at least a factor of four. Sustainable, affordable and top quality!

Proven sustainability within every industry

Every skipper knows the problem; salt water is THE BIGGEST threat to the ship. The solution for electric motors is available. KTC. Make the use of your electric motor more sustainable.

Moisture and detergents are the substances that make the current paint on the motor crumble. Prevent this by using Kolmer Top Coating and make your own production process more sustainable.

From heat to cold. From rain to sunshine. The pump sets that are hired out are really in for a bad time. This explains why they often look battered despite being relatively new. Motors with KTC will give the pump set a neat appearance.

Motors are often positioned in the open air facing all kinds of weather conditions. This explains why they often look battered despite being relatively new. Motors with KTC will look neat and cared for.

The salty sea air will slowly destroy the paint that should protect the motor. Motors are often positioned in the open air facing all kinds of weather conditions. This explains why they often look battered despite being relatively new. Motors with KTC will look neat and cared for.

There is a limit to the amount of paint to be applied to ATEX motors. This has everything to do with preserving the cooling of the motor. KTC gives the motors optimal cooling due to the thin layer required. As a result, the motor will retain its well cared for appearance.
