surface functionalisation & corrosion
OCAS develops new functional and aesthetic surfaces for any metal substrate to meet your specific requirements. Our skilled staff can rely on state-of-the-art equipment to prepare, apply and characterise different coatings: organic, inorganic, metallic, hybrid and/or enamel coatings. Our aim is to optimise your surface functionality, lower your production cost and make your product more environment-friendly.
The complete coating and enamelling process can be simulated in our laboratory, using a wide range of technologies. The first step is the pre-treatment of substrates including for example degreasing, pickling, phosphating and passivation. Coatings are then applied by electrophoresis, spraying (wet or powder paints or enamels), dipping, spinning or using a roll coater. A more advanced technique is Chemical Vapour Deposition, allowing the deposition of very thin layers (20-50 nm) on a variety of substrates. Our curing methods include conventional, infrared (IR) and ultraviolet (UV) curing.
We are able to perform the full characterisation and testing of different technological aspects of surfaces from macro to micro and even to nanoscale: flexibility, adhesion, hardness, wear and staining resistance, colour, gloss, appearance, etc. Both outdoor exposure racks as well as accelerated corrosion cabinets are available to check the corrosion behaviour and durability. In addition to these standardised tests, we are also equipped to perform electrochemical measurements using impedance spectroscopy, Scanning Vibrating Electrode Technique (SVET) and Scanning Kelvin Probe (SKP).

Together with Flanders Materials Centre (FLAMAC), a division of SIM, we make an accelerated development of new coatings possible, thanks to the high-throughput experimentation technology. Specific software and equipment allows fast and precise preparation of the formulations. The High Throughput Technology is based on an automated formulation, application and curing of coatings. This quick screening not only allows for cost reduction. It also reduces the research time to obtain the perfect coating for your application, thus reducing your time-to-market.
