Next steps in the piloting platform upgrade for nanotextured materials

Nanotextured surfaces and nanocoatings offer a means to create unique material properties. The preparation and demonstration of these treatments require a configurable and versatile pilot line with an adequate control system. VTT's Surface Treatment Concept SutCo is being upgraded in the EU NanoTextSurf project. The latest step involved commissioning of the new suction box.

The Surface treatment Concept, SutCo for short, is the pilot-scale surface treatment and coating line located at VTT in Espoo, Finland. SutCo is a versatile research equipment that is used as an open access pilot facility for research and product development activities.

Thirteen partners are cooperating in the EU NanoTextSurf project (2017-2020) to upgrade the SutCo line. The aim is to upgrade the existing pilot line to a level where it is suitable for manufacturing biobased nanotextured and nanocoated special products in industrially relevant scale.

The application of coatings on membranes, textile fabrics and papers has already been piloted at the SutCo line. Based on the observations during these initial tests, several modifications to the line were designed and executed.

The latest effort was to install a vacuum box (middle image) to enhance penetration of a dispersion into porous textile material. First test runs were carried out with different slot openings and vacuum levels.

Top: Basins for chemicals, such as an anchoring polymer, and/or water that can be applied on membranes before the coating operation.

Middle: The newly installed suction box is located after the coating application. It is used to impregnate porous textile webs with dispersions.

This project has received funding (5.8 M€) from the European Union's Horizon 2020 research and innovation programme under grant agreement No 760601.
