Partnering opportunity

Coating with low refractive index sought


A German plastics research institute seeks a partner to supply a coating with high optical transmission and a refractive index of 1,3 or lower for an illumination unit for automotive interiors. This could be done within a manufacturing agreement. Opportunities for a research cooperation could also be discussed.

Technical Specification or Expertise Sought

The optical specifications for the coating are: - refractive index = 1,3 or lower - high optical transmission The physical performance requirements are: - temperature stability at least 90°C

Partner sought

Industrial partners are sought to supply the coating according to the specifications within a manufacturing agreement. There is furthermore the opportunity to cooperate in future research projects for new automotive interior products where the partner would bring in the coating know-how.


A German research institute is specialised in plastics technology for many applications. Within the scope of a project on automotive interiors, the institute plans to develop an illumination unit, e.g. for instrumental panels. For this task the institute seeks a coating with specific characteristics. This coating needs to have a high optical transmission with a refractive index about 1,3 or lower. The substrates in use are polycarbonate (PC) or poly-methyl-methacrylate (PMMA). The coating should be applied preferably by screen-printing. However spray coating or doctor blading would also be an option. Partners are sought who can supply the coating. A manufacturing agreement can be concluded where the partner produces the coating according to the specifications of the German institute. There would also be an opportunity for a future research cooperation if the partner is interested in the joint development of new automotive interior products.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
