What is microcor?
As a zinc flake coating, microcor is like a personal protective suit for your product. The coating material made of zinc, aluminium and an inorganic matrix defends your component like a defensive wall against environmental influences. This way, the substance of the product remains untouched. Learn more about how a zinc flake coating protects your product.
What distinguishes microcor from other zinc flake coatings?
A personal protective suit must fit. If it is two sizes too large or too small, or if it is not tailored to the area of application, it will only provide limited protection. That is why microcor does not come in one size fits all, but is always individually tailored to your component. In every respect.
Optimally adapted layer by layer, microcor ensures that your product delivers what you promise.
What advantages does microcor have for your product?
Innovations – Why is microcor always one layer ahead of corrosion?
For your perfect microcor coating, we don't wait for innovations. We develop them ourselves. That's why EOT has always been on the lookout for new technologies to make microcor even better. And thus also your product.
Innovative process technologies
The microcor coating comes onto your product in many different ways. However, never in a one-size-fits-all process. For your optimal corrosion protection, we develop the details of the coating process individually for each new product. In doing so, we use all process technologies - and also go beyond what was previously conceivable.
In the past, we have already developed completely new process technologies. Techniques that only found their way into the generally known coating technology much later.

Spin coating process for rack fabric
microcor by EOT was the first coating to provide an optimal coating of rack fabric via the spin-coating process.
Today, rack dip spinning – also called spin coating – is a common coating technique for many components. An advantage that EOT customers benefited from before anyone else. Since EOT was significantly involved in the development, microcor was the first coating to benefit from the advantages of the process technology.
Secure a competitive advantage with microcor
To keep you one step ahead of your competition, we never stop making microcor better and better. A decisive advantage for all those for whom their own product can never be good enough.
Why can you rely on microcor for the best quality?
Quality is a big word. And even bigger is what EOT makes of it. Because the microcor coating process includes sophisticated quality management that goes far beyond the obvious. So it's no wonder that we don't rest on our ISO 9001:2015 certification, but set our own standards.
We do not measure our error rate in percent
If we were to calculate the defect rate of our coated parts as a percentage, the number would have so many decimal places that we would have to round it down to 0. And a defect rate of 0% - would you believe us? That wouldn't be honest.
That's why we determine the defect rate of our coated parts in parts per million (ppm). So you know exactly what you can count on.
Why does microcor have such a good quality ratio?
We have big goals: We want every one of your coated parts to be flawless. That's why we do everything we can to achieve that. We don't waste energy discussing defects at length – we simply avoid them from the start.
Targeted quality management even before the first step is taken
With us, the coating process begins long before your batch is delivered. Based on your specifications, we determine every detail of the individual coating process. We weigh every rotation speed, every degree of dryingtemperature and every angle precisely. This prevents errors before they occur.
We check even before the product is ready
Checking the uniform layer thickness when we can no longer influence it? That is too late for us. In contrast to conventional coatings, we check the thickness of your microcor coating while it is still wet, before drying.
And to ensure that not only the coating thickness but also the composition is perfect, we also continuously test the coating material - before it even touches your product.
We use only high quality raw materials
A high-quality product deserves high-quality protection against corrosion. And this only comes about when the raw materials of the coating also meet the highest quality standards.
We therefore obtain the raw materials contained in microcor exclusively from suppliers we can rely on. Long-term supplier relationships have developed into partnerships long time ago. With a common goal: the best protection against corrosion.
For the coating media, we rely exclusively on renowned and certified German manufacturers such as Dörken or Magni.
All tests under a strict eye
We carry out the final testing of your component directly on site in our laboratory. In this way, we receive the results of the coating process particularly quickly.
This applies to components coated with microcor and, if required, to all others that we test on your behalf. Because you can use our laboratory services for all your products if you wish.
SALT SPRAY TEST
KESTERNICHTEST
COEFFICIENT OF FRICTION TEST
Salt spray test
Does the coating withstand the salt spray test for exactly as long as the standard for your component stipulates? We test the durability of the coating in the salt spray test under exact compliance with the prescribed conditions.
Kesternichtest
The Kesternichtest is the hardness test for your product and its personal protective suit of zinc flakes. Under the worst possible conditions, we test here how long our microcor coating defends your product against corrosion.
coefficient of friction test
Just testing the resistance of our coating is not enough for us. We also want to prove the friction values of your component in black and white. That's why we carry out a friction value test directly on site.
Does microcor fit to your application?
microcor stands for individual coating solutions. That's why we rethink every coating for every application. And thus create the optimal coating for almost every requirement - including yours.
Which products does microcor protect against corrosion?
Screws
microcor protects almost all types and sizes of screws against corrosion. Even screws with metric threads according to DIN requirements receive precise protection within the range of tolerances.
Springs
So that springs retain their spring stiffness in any environment: microcor provides all types of springs with long-lasting protection against environmental influences. At the same time, it is also possible to improve the function, for example by reducing squeaking noises.
Threaded rods
Thanks to various coating processes, threaded rods and bolts in almost every size receive their individual microcor coating. This makes them safe from corrosion in the long term - even in challenging applications.
Nuts
With the best machines and individual processes, nuts still fit exactly on the screw thread even after coating. The material is safe from chemical reactions even in aggressive environments.
Washers
Thanks to the optimised coating process, small-part products receive their precisely fitting coating in large batches. You will receive your washers coated wafer-thin, checked several times and back on schedule.
Tubes
To ensure that your tubes remain leak-proof in the long term, microcor protects them from the influences of the environment. Thanks to the careful selection of materials and processes, no pollutants are transferred to the goods transported in the pipe
Turned parts
Even complex turned parts receive a wafer-thin corrosion protection at all points with microcor. In this way, it reliably protects against rust without jeopardising the fitting accuracy of the product.
Stamped parts
During the individual microcor coating process, even sensitive stamped parts remain free from mechanical damage – while at the same time even complex products are optimally coated.

How microcor finds your product
The optimal process technologies for your product
There are various ways to apply the material. In principle, however, all the materials used can be processed with all the methods described.
The decision on which type of coating to choose depends on the parts and on the requirements placed on the finished surface and is decided on a case-by-case basis.
Basically, a distinction is made between the processing of pourable small parts in centrifuging processes and rack goods in dipping, spraying and spin coating processes.
Dipping and spraying
Particularly even for the perfect look. Of course, the coating materials can also be processed using these conventional coating techniques. We choose one of these ways in order to leave nothing to be desired in terms of part optics in addition to the highest requirements for corrosion protection. The use of fully automatic coating systems and robot technology ensures the uniformity of the coating in conjunction with highly innovative adjustments in the application of the materials.
Spin-Coating
Particularly effective for hollow spaces. This process makes it possible to combine the advantages from centrifuge coating with the decorative requirements for rack goods. The pre-treated parts are placed or hung on support frames. These product carriers are then dipped into the coating material. All-round wetting, even in hollow spaces, is ensured. Any excess material is then spun off in an oversized centrifuge. With suitable parts, a high throughput with extremely low material losses can be achieved with this process.
Centrifugation
The standard for small parts and bulk material. Bulk small parts are sensibly processed in coating centrifuges. For this purpose, the parts are poured into coating baskets and then placed in the combined immersion centrifugal unit. Due to the centrifugal forces, excess coating material with defined parameters is spun off. The parts are then baked in a continuous process. Centrifugal speed, centrifugal time and also the viscosity of the coating material are decisive for the coating thickness to be achieved. In order to be able to coat even complicated, e.g. scooped parts cost-effectively, different centrifuge systems are available. Coating in such plants offers an optimal price-performance ratio. For example, fasteners are not processed in our company in standard machines due to the problems of gauge retention and internal drives. This part is taken over by specially designed machines.
