Primer application is a challenge in many industries. They’re distinguished between water-based primers and solvent based primers. Axel Wirth Maschinen GmbH offers different solutions for those types of primer.
1. Water-based primer:
Application of the primer, using a dosing roller machine type DWO. The primer is being pumped into the rollers and circulates within the machine. When using the machine in hot environments, the viscosity can be measured and automatically adapted. Rubber coated rollers, are being used for that, which can be smooth, grooved or porous, depending on the desired application amount. Following that, a infra-red dryer can be patched in. Our machines are currently being used with the following water-based applications in the
2. Solvent-based Primer:
Using solvent based primers will become necessary in different fields. Challenges resulting from that were mastered by us multiple times in the past. Following things need to be considered:
Explosion protection of the plant, or EX-protection of roller coating machines in short. The solvent-based primers usually have an extremely low flashpoint, that makes the usage of EX-protected motors, sensors, circuitry, etc. necessary. We can assure this also in cooperation with specialized audit companies. This of course does have it’s price, but sometimes it’s not possible otherwise.
Die lösemittelhaltigen Primer haben in der Regel einen extrem niedrigen Flammpunkt, der den Einsatz von EX-geschützten Motoren, Sensoren, Schaltung.... nötig macht. Dies können wir auch in Zusammenarbeit mit Prüfgesellschaften sicherstellen. Das Ganze hat seinen Preis, aber manchmal geht es nicht anders.
Keeping the viscosity stable. As additional point, it needs to be considered, that the solvents volatilize and thus the viscosity will change. That’s why it’s mandatory to monitor the viscosity and to adapt it with the addition of solvent. Otherwise you take the risk of the application amount changing through the change in viscosity.
Solvent-based primers and the rubber coating of rollers.Depending on the producer of the primer and the type of primer, the mixture of the solvents are a challenge for the rubber mixtures of the roller coaters. We always examine the compatibility of the rubber mixtures and the used primers in advance. Currently we got over 80 different rubber mixtures in use, so mostly a existing rubber can be found for the different types of primer.
Areas of application:
To verify if we can offer the right solution for your primer application, a test in our technical center is an important step.
Should we have sparked your interest, please get into contact with us and arrange a testing day at our place in Oberkochen.
Thanks to the flexible systems, it is also easily possible to produce special parquet. Accordingly, the customers are, on the one hand, large manufacturers in the parquet industry who use the flexible systems for special surfaces, or there are parquet dealers who want to create their own special surfaces.
Thanks to the quick roll changes and the huge selection of roll surfaces, Axel Wirth Maschinen GmbH offers a wide range of options.
There are over 80 different rubber compounds, so it is always possible to find the right roller for the right application.
Regardless of whether the hardness, grooves or chemical resistance is the challenge. There is almost always a solution.

is standard and possible without any problems. The further steps such as drying, stacking, intermediate sanding can be supplied, instructed and put into operation from one source as a system. All machines from Wirth are modular and can be added at any time. Thus, the surface system can grow in step with the tasks
If you are interested in a test run, you are welcome to arrange a test day in our technical center.

Safety relevant parts in the automotive industry are not rarely glued with Axel Wirth Maschinen GmbH’s machinery. Besides brake linings for sports cars, drum brake linings for trucks, brake linings as individual items for oldtimers or elevator brakes. Depending on the brake lining, often times solvent-containing adhesives are used. But Water based adhesives or glues also find their entry into the market. But as long as those still represent the minority, adjustments of the standard machines are necessary.
For that, our roller applicators type LW 100 or DWO are being used. It’s clear that process security needs to be top priority when it comes to safety relevant parts like brake linings. According to that, Axel Wirth Maschinen GmbH can look back on longstanding experience from production planning to implementation. Besides gluing of brake linings for automotive-, truck-, or elevator –sectors, we’re also operating with the inking or priming of narrow sides of drum brakes in those business segments. Should you have applications in this area, you can arrange a appointment with our technical center at any time, to conduct preliminary tests on our laboratory plants. If you’re interested just contact us, we’ll promptly get in touch with you for further details.
The trend of gloss-painting plastic material edges still persists as strong as ever. As new addition the product range, “Axel Wirth Maschinen“ developed a new method which is very reliable, delivers high stability in it‘s process and is also affordable. This technology is available as a single module or as complete plant for paintwork, featuring a dryer system for furniture edges with UV-gloss paint.
This is based on the technology which we’ve already established on the market since some years. The optimization of our roller applicator type DDWO brought us a step closer to our goal. The further development of Axel Wirth’s paintwork technology now made it possible to create highly glossy surfaces with just a single application of paint, completely free of structure.
Doesn‘t matter if smooth, embossed or brushed surfaces are to be coated. It also functions on all plastic material edges, wood, cork, tin, stainless steel and many other materials. We are using the know-how of over 30 years. The film of paint of course shouldn‘t be too thick, otherwise it would break when rolling-up. Since the production procedure of gloss paintwork is very complex in itself, it can only work in proper combination of mechanical engineering, roller specifications, speed, paint specifications and many other details and circumstances. Since we’re specialized and an expert in those matters, we can offer single stations for unit loads or coil. The spectrum of our goods and services includes the machinery for coating and can, if needed, also be winded and unwinded. We would be pleased to make a test with your base materials and paints in our testing facility.
