The potential of functional and smart coatings explained at Materials

slimme coating

The Materials trade fair, which takes place on 31 May and 1 June in Veldhoven, has a practice-oriented set-up themed around four pillars: materials, surface techniques, joining techniques and analysis techniques. Keynote speeches and live demos will be presented in the different Experience Areas to inspire visitors. Sirris will also be present with its expertise in (functional) smart coating techniques.

During Materials the smart coating department will also be present with a stand (no. 105) and Walter Lauwerens from the Smart Coating Application Lab will give a presentation about smart coatings. The term functional coatings is usually used to refer to functions other than decoration or protection. Everyone has heard of coatings with anti-graffiti, self-cleaning, antibacterial or antistatic properties. But it goes even further when the properties of the coatings change in function of temperature or pressure. In that case we speak of ‘smart coatings’ which can be used as sensors, for example.

The presentation will give an overview of technology and applications of functional and smart coatings. Sirris’ Smart Coating Application Lab supports companies interested in applying these coatings on their products with the advice, optimisation, demonstration and industrialisation.

Exhibition

Some demo items of the Smart Coating Application Lab will be displayed at the exhibition, to illustrate some technological innovations:

  • functional coating on plastic products made with additive manufacturing, to reduce the manual or mechanical post-processing time to a minimum and improve the turnaround time of functional 3D products.
  • Sirris recently bought a femtosecond laser which makes it possible to add extra functionalities to surfaces via micro textures, including water resistance, optical effects, anti-icing and haptic, hydrodynamic or aesthetic properties. The exhibited item shows a water-repellent micro structure and how different laser parameters affect the functionality 

     
  • metallisation of plastics by applying a combination of physical vapour deposition (PVD) and spray-coating. A thin (< 1µm) metallic coating is applied by means of PVD, followed by a mat or glossy clearcoat which is applied by means of spray-deposition and uv curing for the protection of the metallic coating. For high gloss effects on plastic samples which initially have a rough surface, a nivellating basic coat is first applied.

     

Fair floor 

With more than 85 participants and about 40 knowledge sessions the trade fair Materials wants to make a connection between science and practical applications. Each of the four pillars on which the fair is built shall be assigned its own area at the trade fair location. Within a certain zone the exhibitors will be positioned around collective Experience Areas where they will give live demos or where visitors can set to work. Every area also has a separate seminar room. 

Besides the Smart Coating Application Lab the SLC-Lab is also present at the fair (stand 70) and with its own presentation.
