Do you know LUWITAN®?
LUWITAN® – a name that many of our customers have long since integrated into their everyday work. But what is actually behind this name?
LUWITAN® is Lutze Group's protected brand name for high-quality polyurethane solutions that were specially developed for molded parts and wear-resistant coatings. The history of LUWITAN® began in 1965, when Heinz Lutze Senior and engineer M. Winkler were looking for a solution for coating conveyor belt rollers with polyurethane. The result: an innovative system that quickly became a success.
The name LUWITAN® reflects this collaboration:
- "LU" stands for Lutze,
- "WI" for Winkler,
- and "TAN" refers to the suffix of "polyurethane".
Flexibility and innovation
LUWITAN® stands for tailor-made polyurethane solutions based on a variety of proven recipes. Thanks to our protected brand and our broad raw material network, we are not tied to individual suppliers. This enables us to react flexibly to market changes and provide the optimal solution for every requirement - with consistently high quality and performance.

Coatings with LUWITAN®
Tailor-made solutions for your requirements
More than half of the components we manufacture from LUWITAN® are coatings - proof of the versatility and quality of this technology. Our main focus is always on the optimal bond between LUWITAN® and the coating carrier (core). Through intensive laboratory tests, close cooperation with our customers and our own series of tests, we have continuously perfected our coating technology. Thanks to these developments, we can now coat not only classic metallic materials, but also materials such as wood, plastics or rubber.
Flexibility in core provision
You can provide us with the coating carriers or, if you wish, we can take over the production or procurement of the cores according to your drawings and specifications.
Diverse coating processes
To coat your components with LUWITAN®, we use various processes that are individually tailored to your requirements:
- Open or closed molding processes: For precise and uniform results.
- Spin coating: Particularly suitable for coating pipes and containers.
Rely on the latest coating technology that offers you maximum flexibility and quality. Together we will find the perfect solution for your application.
Our quality promise
Precision and reliability in every step
Quality is our top priority. That is why we ensure that all relevant processing times and process steps are strictly adhered to when processing LUWITAN®. This is the only way we can ensure that every component meets the highest standards.
Precise adherence to pot life
The pot life - the period in which the material must be introduced into the mold - varies between two and ten minutes depending on the recipe. It begins when the components come into contact and ends when the setting process starts. To ensure the best quality, the casting takes place directly from the machine's mixing head into the mold.
Exact process times for optimal results
Depending on the component, geometry and selected LUWITAN® quality, the demolding process takes a few minutes to several hours. After demolding, the PU components are reworked in a precisely coordinated tempering process. Different times and cycles are adhered to, depending on the respective recipe. In addition, the physical properties of the cast parts can be further improved by storing them at room temperature for 14 days.
Continuous quality control
Our production is constantly checked for visual defects and hardness fluctuations. If there are any deviations, we react immediately with targeted measures. In addition, we produce test plates of each recipe every day, which are archived to enable subsequent checking of the physical properties of a production batch.
With our quality promise, we guarantee you LUWITAN® products that meet the highest requirements - reliably and precisely manufactured.
