Excimer coatings – UV coatings for extremely matt surfaces
An interesting alternative to the classical matting processes is the physical matting with so-called excimer UV rays.
In this innovative method, the liquid UV-curing excimer coating "Innolux Topcoat EXC" applied in the rolling process is irradiated with short-wave UV light (172 nm) in the absence of oxygen. This leads to superficial polymerisation, which causes volume shrinkage, which 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. For complete curing of the coating layer, it is irradiated immediately afterwards with a UV dryer.
ADVANTAGES OF EXCIMER TECHNOLOGY AT A GLANCE
- Dull matt gloss levels without matting agent (gloss levels from 3 to 20)
- Extremely scratch and abrasion resistant coated surfaces
- Increased surface hardness
- Outstanding chemical resistance
- Soft touch effect
- Anti-fingerprint effect
- Perfect reproducibility
- Pleasant feel
- No solvents
Improves efficiency in the coating process, optimises series production, saves time and costs
Innolux TOPCOAT EXC is a latest generation excimer coating – for dull matt surfaces with anti-fingerprint properties. We will be happy to advise you on the excimer technology without obligation.
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).
