Excimer coatings: UV coatings for extremely matt surfaces
An interesting alternative to the classic matting process is physical matting with so-calledexcimer UV rays. ADLER have developed their own excimer coatings for this innovative process and have extensive expertise in this technology through the use of their own excimer system in their Application Technology department.
Excimer
Extremely matt surfaces
Excimer process
With this innovative method, the liquid UV-curing excimer clear topcoat "Innolux Topcoat EXC", which is applied using a roller, is subjected to radiation with short-wave UV light (172 nm) in the absence of oxygen. This results in surface polymerisation, which causes volume shrinkage, and this in turn manifests itself in surface folds of varying degrees. This deformed "skin" leads to a diffuse reflection of light, which we perceive as a matt effect. To ensure complete curing of the coating layer, it is irradiated immediately afterwards with a UV dryer.
Excimer coatings
ADLER's excimer UV coatings provide ultra-matt and extremely scratch-resistant surfaces. Thanks to the innovative excimer technology, a wide variety of surfaces and geometric shapes can be coated with extreme precision.
Advantages of applying ADLER coatings by means of the excimer process:
• Dull matt gloss levels without matting agents
• Coated surfaces that are extremely scratch-resistant and abrasion-resistant
• Increased surface hardness
• Outstanding chemical resistance
• Soft-touch effect
• Anti-fingerprint effect
• Perfect reproducibility
• Pleasant to the touch
• No solvents
With excimer technology, you can increase efficiency in the coating process, optimise series production and save time and money. We would be happy to offer you a no-obligation consultation on excimer technology!
Roller and curtain coating application using the excimer process
For the roller or curtain coating process, we suggest using "Innolux Topcoat EXC" excimer clear topcoat. This UV-curing topcoat was specially developed for the combination of roller/curtain coating application and the subsequent Excimer matting process.
Innolux TOPCOAT EXC is a new generation excimer clear topcoat – for dull matt surfaces with anti-fingerprint properties. With excimer technology, you can increase efficiency in the coating process, optimise series production and save time and money. We would be happy to offer you a no-obligation consultation on excimer technology.
ADLER will perform tests for you to establish the perfect workflow
We are also committed to providing our customers with the best possible support in the planning and fine-tuning of their own coating application systems. That's why we have our own excimer system in our machinery pool. This allows us to test the processes in a laboratory setting and pass on the insights we gain and the reports we draw up from practical experience.
OUR SERVICES
Together with our industrial partners, we adapt the entire application including plant configuration to your needs. Before commissioning, we carry out tests of the entire system (coating, substrate, excimer radiators and UV curing).
