Frequently Asked Questions

DIN EN 14879-1 provides detailed information on the requirements. However, there are exceptions. For example, some plastics are more tolerant of deviations than others, while specific uses or coating plastics require more stringent requirements. We will therefore be happy to check this for you individually.
The standard is quite extensive. We have compiled a summary(open standard summary).
Provide us with the best possible documentation for your individual project. You can use our enquiry form to collect the most important data.

Give us a precise description of the application. A simple questionnaire will help you to collect the data(enquiry form).
In cooperation with the laboratories of various manufacturers of coating materials, we will endeavour to find a solution for your individual project. If it is not possible to give a clear approval or rejection, we will be happy to provide you with test samples for practical trials under real conditions.

Document the operating parameters as precisely as possible: contact product, temperatures, chemical stress, required approvals.
HÜNI + CO has experience of suitable coating processes for many applications. We select non-stick coatings from our range that are suitable and that you can also test using coating samples.

Various components play a role, e.g. the electrical voltage, the substrate, the component geometry or the desired plastic.
Please describe the process to us as best you can(contact form) or contact your local HÜNI+CO representative.

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

No. Depending on the severity and size of the corrosion damage, it is also possible to repair or recoat the workpiece.

This is often the case. However, there are exceptions, as in Germany, for example, the Federal Office for Risk Assessment (BfR) applies different criteria. An individual examination is therefore recommended.
