Today, the search for more environmentally-friendly coatings for packaging papers, as a sustainable alternative to plastics, is taking up speed. Paper as a possible substrate scores high, but has a few drawbacks. In view of compatibility with the papermaking process and final recyclability, the deposition of waterborne coatings is preferred when including renewable materials. New concepts for both the protection of packaging papers with a coating, as well as recycling coated papers should be considered.

Biofilms - layers of micro-organisms in a mucus layer which is adhered to a surface - are considered a nuisance in many sectors and are therefore fought against. However, they also offer protection and can be useful, for example, as a living skin for architecture, which is what an innovation project assumes.

Understanding behaviour and performance of drones in adverse weather and harsh flight environments is a prerequisite to developing meaningful test protocols for the validation and certification of these flying systems. An exploratory work investigates the development of a method for characterising the performance of propellers in laboratory icing conditions, as considered the most critical. This research was enabled by the use of a climatic chamber featuring an array of water nozzles that makes it possible to generate icing condition, in combination with a windshaper.

Paper and cardboard are ideal packaging materials through the renewable origin of cellulose fibres, their high specific rigidity and light weight. To increase the quality and shelf life of packaged foods, the performance of paper needs to be adjusted through barrier coatings offering protection against water, gas permeability or aroma preservation. What about the suitability for recycling of these coated materials? Can they be reused in paper production? The Repac2 project aims to evaluate functionality and recyclability of paper for food packaging.

Stricter regulations are limiting the use of classic biocides and lowering their permitted concentrations. As a result, the paint industry faces major challenges in ensuring the durability and storage life of water-based paint systems. At Techniline we offer an overview of possible technological alternatives for preserving paints. Bio-based antimicrobials are certainly suitable for this purpose.

Prior to their introduction to the market, bio-based products are extensively tested. In this respect, there is a growing interest in sustainability tests, especially for demanding applications, in new test methods and in the right test methods. Let’s have a look at today and tomorrow.

What is profitable today will have been replaced by a better solution by tomorrow. You know better than anyone else the need for innovation to stay ahead of your competitor or partner. New technologies often lie at the root of these changes. This is no different when it comes to surface treatments. Stay up to date!

On 2 December Sirris is organising the masterclass 'Corrosion solutions for offshore renewable energy devices', which will cover the challenge of corrosion in offshore renewable energy and targets a broad audience from the entire offshore value-chain, including problem owners, solution providers, O&M companies and research institutes. Six speakers will give a presentation. In this blogpost we will give you a glimpse of three.

Icing events during wintertime or at high altitudes still form a major obstacle in many industries, such as aviation, construction, (wind) energy and transportation. Companies are seeking for solutions to mitigate ice or to limit the efforts of ice removal. Research is often focused on designing new structured surfaces or using advanced coating technologies. In order to fully understand the potential of such technologies, there is a need to test such systems in realistic environments. Sirris comes prepared.

The application of nanotextures with ultra-short pulsed lasers remains interesting for many applications and LIPSS (laser induced periodic surface structures) is the most widely used technique. A newly developed module makes it possible to achieve more precise, higher-quality structures, even on large surfaces. This is particularly interesting for anti-icing surfaces, as applied in aviation or wind energy.
