Traceless removal of digitally printed protective films
The Swiss watch industry focuses on perfectioning their capabilities since its beginnings. The use of printable, protective elements during surface finishing processes would allow for a new level of resolution and complexity. Nevertheless, currently used materials are not printable due to their high viscosity and are often hard to remove. We therefore are developing a printable polymeric coating that allows for traceless removal with water.
Polyethylene glycol (PEG) is a widely used polymer that – due to the wide range of commercially available variants – offers the possibility for tuning a formulation to the specific needs of a specific use case. Here, using a hydrogel based on PEG-acrylate, we want to develop a temporary mask that fulfills several criteria, including printability, protective capabilities and swelling that removes the gel from the surface. During the project, you will have the opportunity to find the influence of different ingredients and their relation on the final hydrogel, using rheology and other testing methods. In addition, you will be involved in the development of a demonstrator, that shows the applicability of our novel material in industrial processes. We are offering you a supportive and creatively stimulating research atmosphere in which you can explore a wide range of experimental techniques and bring in your own ideas.

You are learning to formulate a new material and to find ways to characterize the material’s properties. For the demonstrator, you can live out your creative side and help to make it as exciting as you want it to be.
