Dr. S. Lazzerini: The research and development department is the core of Arsonsisi whole activity, because only by keeping up with the changing needs of the market it is possible to remain competitive.
Within the Berlingo production plant, Arsonsisi has created a Competence Centre for the development of UV technologies, cooperating with installers, raw material suppliers, and analysis laboratories to manage specific, tailor-made projects in synergy with customers and different research institutes.
In addition to the laboratory for the development of UV coatings, this plant houses a testing laboratory for raw materials and finished products and a research laboratory for non-UV thermal products.
Dr. S. Lazzerini: The laboratory for the development of UV coatings is equipped with a dry spray paint booth, a COWLES bench disperser for the preparation of pigmented products up to 40 kg, standard laboratory instrumentation, and a UV tunnel.
The UV curing device supplied by UV Ray (Cornaredo, Milan) is the latest innovation of the laboratory.
We introduced this new device to streamline the activity of our lab. That is why we explicitly required UV Ray to equip the oven with a plastic case to prevent our operators from using UV protections, which would otherwise be mandatory because the rays can harm eyesight: this facilitates work.
Moreover, previously there was only one UV tunnel used by both the testing and UV coating labs, with easily understandable overlapping issues.
Thanks to the UV Ray oven, we have now separated our two activities and solved the problem.
Dr. S. Lazzerini: We needed to find a tool enabling our operators to set variable parameters without limiting to any specific type of workpiece or process.
The UV Ray tunnel has perfectly met these needs, because it is a very versatile and efficient system.
First of all, it allows adjusting the advancement speed of the parts positioned on the conveyor belt.
Secondly, it enables to vary the height of the UV lamp, thus increasing or decreasing its distance from the sample and making it possible to cure even three-dimensional objects with complex shapes.
Finally, it allows adjusting the mercury lamp power from a few W/cm2 to a specific maximum power of 180 W/cm2.
A further benefit is the energy saving guaranteed by the UV Ray system. Turning on and off a UV lamp reduces the tool’s service life by 3 hours, thus resulting in rapid wear. The UV Ray tunnel has been designed in order to enter stand-by mode to allow the lamp to save energy.
The flexibility of this device is fundamental for us, as the UV sector is expanding and every day we are faced with very different requests in terms of type and size of parts. An instrument with such flexible characteristics enables us to meet even the most particular needs.
Dr. S. Lazzerini: We are focused on pre- and post-UV coatings for sputtering processes on plastics and metals, 100% dry UV coatings, water-based UV coatings, LED lamp hardening coatings, and UV coatings for the automotive sector.
As for the development of UV coatings that harden with LED lamps, our UV Ray system is ready for the possible addition of LED lamps or the replacement of the mercury-based one currently in use.
We intend to devote ourselves to the development of this type of paint in the future, but we looked for a tool that allows replacing the lamps without forcing us to purchase a specific instrument with LED lamps.
Dr. S. Lazzerini: If lawmakers do not establish a deadline for the ban on chromium VI, the market, especially in the automotive industry, will continue to use traditional systems.
The galvanic process will continue to be counterposed to the physical vapour deposition (PVD) technology, which is the most ecological alternative on the market and, in addition to giving the same results, allows treating different materials.
In this framework, Arsonsisi has developed three systems for PVD sputtering coatings:
Dr. S. Lazzerini: Our R&D department has already completed and presented to the market numerous projects. Other studies have been completed, but they are not easily accepted by the sector, such as those relating to powder coatings for MDF.
The main difficulties, especially for coating contractors, concern the high investment required to install a UV curing system also optimised for cross-linking coatings on complex three-dimensional parts and for handling large batches.
However, the very big orders are now handled in China, whereas European coaters tend to characterise their production by applying special coatings on small batches. Therefore, making such a large investment can be an issue for them.
On the other hand, the systems that include PVD sputtering coatings are now fine-tuned and they work very well, so much so that they are now starting to be requested by our most far-sighted customers (even those using conventional galvanic processes) that want to avoid being in trouble when lawmakers will definitively ban the use of CrVI.
Of course, our research activity cannot stop at the results obtained. Having found reliable partners for the supply of the right equipment is a further guarantee that our projects can be developed flexibly and quickly and with the proper safety measures for our operators.
The wood industry benefits the most from low-temperature powder coatings technology.
This is the reason that led Arsonsisi to focus its work on the development of formulations that meet the needs of MDF market, a technical support widely used in the wood industry.
MDF performances change depending on the variation of the following material features: paintability, depth of furrows, sanding, resistance to craters in the edges, conductivity, degassing (water and additives).
Through careful selection of the resins, additives and wood fibers used, it’s possible to produce best MDF for the application of powder coatings.
There are several advantages related to the use of powder coatings on MDF, both in substitution of laminate. In the first case it’s about freedom of design (curved shapes and edges without joints), flexibility in terms of colors and surface aspect, homogenous texturized surface both visual and tactile, ease of application and manageability, reduction of process costs.
The advantages with liquid are elimination of VOC emissions, elimination or reduction of intermediate sanding, use of 97% of powered coatings used, easy recycling and absence of waste treatment, full application on the edges in a single phase.
The traditional way of powder coatings application is based on electrostatic techniques and requires conductive substrates to work.
Since MDF is a non-conductive material, there are methods to make it so such as the introduction of conductive agents in its formulation or the application of a conductive liquid primer before proceeding with powder coating the support. Once dried it is possible to apply powder coating.
The most effective method is the pre-meating by IR lamps on both panel’s sides, whose temperature once out from infrared oven must be about 90°C.
The coating of the substrate must take place within 1 or 2 minutes from the preheating process using a tribo or crown spray gun.
The best results are obtained using a combination of infrared and convective heat. On the other hand, it is possible to use infrared heating only.
It is essential to use a MDF of adequate quality: some supports are so conductive that the powder coatings can be applied without preheating. However, since the quality of MDF may vary from batch to batch, it’s advisable to preheat to obtain an homogenous film thickness on the whole item.
Light preheating with IR allows additives migration from the MDF substrate to the surface, making the panel more conductive and easy to coat.
The Selac® XFC — Extra Fast Curing Powder Coatings and Selac® UV powder coatings range is the result of a fifteen-year work of Arsonsisi R&D laboratories: powder coatings thermosetting for thermal crosslinking (XFC) o UV.
Selac® XFC powder coatings are particularly suitable for low quality requirements such as those of shelves, TV/PC stands, desks and standard furniture for general use, considering the lower costs/m2 compared to UV products.
They need a single melting and polymerization step and between 10 and 15 minutes of processing time.
While Selac® UV products are used for high quality requirements such as office furniture, kitchens and more because of the high mechanical and chemical properties which characterized them.
These lasts are subjected to a drastically reduced thermal stress considering XFC products and they require process times of about 5 minutes.
Currently there are few powder coatings UV e XFC lines for MDF, but an evolution in this sector is expected and Arsonsisi is leading a market analysis to define needs and find new solutions.
La Rivista del Colore celebrated its 50th birthday and took stock of the next 50 years of industrial coating together with industry experts in the relevant fields of activity: manufacturing, economics, design, education and surface treatment.
It was a day of celebration to reflect on the past, present and future of industrial coatings, and to become more aware of the concept of sustainability. Supported by first-hand experience, entrepreneurs and professionals shared their individual visions and encounters with those present.
What has changed over the years in the world of industrial coatings?
The answer can be found in the book “Storia della verniciatura industriale in Italia” (History of Industrial Coatings in Italy).
La Rivista del Colore traces its long journey in the pages of its magazines. They scan time and narrate the story of industrial coating from the 1960s to the present day, enriched by the tales of those companies that have been the protagonists of these years of change.
And among these entrepreneurial organisations, with the company celebrating 100 years of business last year, Arsonsisi’s contribution could not go amiss.
Presented for the first time during the event, the book is being published in two volumes dedicated to the metal and plastic, and wood industries. They have been written by Danilo O. Malavolti – President of Anver – and Gianni Giardina – former owner of Giardina Officine Aeromeccaniche – respectively.
In the afternoon, Arsonsisi’s representatives, alongside those of other manufacturing companies for installations, machinery, systems, and raw materials, powder coatings and liquid coatings, as well as spokespeople from the academic world, met at a round table to discuss the topics of sustainability, research, innovation and circular economy. Together, they examined the future of industrial coatings.
The day ended with a guided tour of the Toti submarine, recently restored thanks to the efforts of Danilo O. Malavolti, Founder of La Rivista del Colore, and the contribution of a number of companies in the industry.
Modules B and D of the MED certifications attest to the full compliance of the coatings in terms of the low rate of flames-spread on equipment surfaces for interior ship fittings.
The Arsonsisi products that fulfil such requirements are the B series epoxy powder coatings; J, Y and Z series polyesters; and E, F, G, H, K, PH, Q and X series epoxy-polyesters.
We are very pleased to have received this approval for many series of different chemistry with a wide choice of finishes and effects for the shipbuilding industry. Passing the strict tests provided for by the MED Directive is further confirmation of the quality of our products.
Says Ivan Fornari, Arsonsisi’s Sales Director.
Totally revamped in its graphics and navigation paths, Arsonsisi’s new e-commerce website has been designed and developed to improve the user’s experience and make online order acquisition and management easier.
4 years after its launch, Arsonsisi presents a more modern and functional version for the ecommerce of its powder coatings, capable of enhancing the user’s shopping experience.
Arsonsisi first introduced the powder online purchasing service in Italy in 2014.
It was a courageous choice, motivated by the subcontractors’ request for more flexibility and autonomy in order management.
States Cristoforo Brendas, Powder Coatings Business Manager in Italy.
The new e-commerce website has been realised by Overweb, an IT and web services company from Milan, with Magento, one of the best and most widely used open source CMS that offers many functions for the development of online purchasing platforms.
The digital world is constantly evolving and it is important to keep up to date with the times if you want to be competitive.
Apart from the graphics and design, the improvements affect mainly the navigation path, order management process and optimisation of internal search with clearer and more intuitive filters for colour, price, finishing effect and chemical nature.
Explains Luca Troiani, Powder Coatings Area Manager Italy and Project Leader for Arsonsisi’s new e-commerce website.
Customers ordering Arsonsisi coatings benefit from the same advantages as when they use the main e-commerce sites for private purchases: cheaper prices and reserved promotions, access to their customer accounts to check their order and invoice history, simple and fast order processing, easy access when using mobile devices and safe payments.
Arsonsisi’s e-commerce website is also a support tool for customers’ daily activities, since, on each product page, they can immediately find the information on the preparation and application of the coating and can download the technical sheets of all the codes on the online catalogue at any time.
The service is currently available to purchase only powder coatings in Italy, but Arsonsisi is planning to extend it also abroad and to the sale of other industrial painting lines.

And it’s no wonder, because with its comprehensive overview of the industrial coating technologies market, PaintExpo is meanwhile the number one information and procurement platform for users from all over the world.
The 7th PaintExpo edition was bigger than ever. With an increased exhibition floor space offering an additional hall, 537 companies coming from 29 countries and 11,790 visitors from 88 countries, the Fair observed an increase of 12%.
After Germany, the most well-represented visitor countries were Switzerland, Italy, France, Austria, Poland, the Czech Republic, the Netherlands and Turkey.
Arsonsisi was also very satisfied with this edition and welcomed a great number of visitors to its stand, where its complete range of industrial coatings was displayed.
Arsonsisi and Tonon Forty have been cooperating for many years to always get top results and guarantee the high quality of their products in the name of the excellence of the Made in Italy.
The new range Colors Vintage is born of this historic partnership, a reinterpretation of the Colors lamellar radiator, Tonon Forty’s spearhead since 1967, with finishes inspired by simple materials such as copper, aluminium, stone and soil, to create evocative environments.
The search for the right colour and effect combination was fundamental to characterize the design of the Colors Vintage line, which finds its maximum expression in the Vintage Corten finish, where the colour lets you see all the elements in all its shades.
The Copper, Aluminium and Stone finishes are made by painting with coloured epoxy-polyester powders, while the Vintage Land and Vintage Corten finishes are obtained with a particular process on the untreated radiator, followed by the application of clear industrial polyesters.
Our design department has worked closely with Arsonsisi sales department.
Comments Arianna Giuseppin, Marketing Manager in Tonon Forty.
Arsonsisi professionalism and technical assistance helped us a lot in the implementation of this project and have been crucial to the success of the Vintage range.
But «beyond colour there is also value«, citing Assovernici’s Colore Sicuro.
Arsonsisi has adhered to Colore Sicuro with the commitment of supporting certain values inspired by the respect for the recipients of its paints, the Company and the environment.
The uniqueness of these two historical Italian companies lies specifically in their values.
The cooperation with Arsonsisi confirms once again Tonon Forty‘s attention to quality, safety and the environment through the choice of eco-friendly technologies and the safeguarding of employees, contractors and clients’ health and all with a fully transparent approach.
Values fully shared by Arsonsisi.
