• High-intensity UV radiation (medium or high pressure, UV LED) causes immediate polymerization of the oligomers and monomers contained in UV formulations.
• Calibrated spectral emission (UVA, UVB, UVC) optimized according to the photoinitiators used in the formulations.
• Dynamic exposure control (intensity, duration, spectrum) guarantees complete crosslinking without overheating the substrate.

• Instantaneous : cures in fractions of a second, eliminating intermediate drying times.
• Material compatibility : treatment of heat-sensitive substrates (engineering plastics, composites, wood, thin substrates).
• Surface quality : consistent finish, free of dust and inclusions, with controlled gloss or matte finish.
• Compactness : space-saving UV modules, can be integrated in-line or as a back-up.
• Energy efficiency : adjustable power and intelligent control of lamps or LEDs, limiting consumption in standby and partial load.

• UV inks & varnishes : industrial printing, packaging, adhesive labels, plastic or metal substrates.
• UV adhesives & glues : structural and technical assemblies, microelectronics, optics.
• Functional paints and varnishes : scratch-resistant, anti-UV, solvent-resistant coatings.
• Wood and composites industry : high-gloss decorative finishes, varnish curing on panels.

Surfi-Métal offers hybrid UV + IR + convection configurations, suitable for multi-process production :

• IR preheating to reduce viscosity before UV curing;
• UV-LED hybridization and discharge lamps to combine performance and longevity;
• Coupling with convection tunnels for mixed lines (conventional liquid coatings + UV).

• Zero solvents, zero VOCs : UV formulations do not release volatile organic compounds.
• Drastically reduced cycle times → increased productivity.
• Reduced carbon footprint thanks to optimized consumption and the absence of a lengthy drying phase.
