Frequently Asked Questions

Here we give you the answers to the questions we are asked most often:

DIN EN 14879-1 gives detailed information about the requirements. However, exceptions do exist. For example some plastics are more tolerant to variations than others. On the other hand, specific uses or coating plastics have additional requirements. For this reason we are happy to investigate these individually for you. (open standard summary)
The standard is quite comprehensive. We have compiled a summary for you.
Document your individual project as best you can. Use our requirement form to help you ascertain the most important information.

Describe the application precisely. This basic form will help you to ascertain the information.
Working together with the laboratories of various coating material manufacturers, we try to find a solution to your individual project. If no definite acceptance or rejection is possible, we will happily provide you with test samples so you can carry out practical experiments under real-life conditions.

Document the operating parameters as precisely as possible: contact product, temperatures, chemical stresses and necessary approvals.
HÜNI + CO has experience of suitable coating processes for a wide variety of applications. We will select non-stick coatings from our range, which are appropriate and which you will also be able to test for yourself with the help of coating samples.

Various factors play a part, such as the electrical potential, the substrate, the component geometry or the desired plastic. Describe to us the process as best you can or contact the HÜNI+CO dealer in your region.

Whether non-stick or anti-corrosion coating: many workpieces can be decoated and recoated again several times.

No. Depending on the severity and size of the corrosion damage the workpiece can be repaired or recoated.

This is often the case. However, there are exceptions, as e.g in Germany the Federal Institute for Risk Assessment (BfR) lays down other criteria. Subsequently an individual test is recommended.
