What is UV curing ?
- Principle -
UV curing is a photochemical reaction to cure or dry inks, varnishes or coatings using high-intensity UV-A light. Liquid formulations contain a mix of monomer and oligomer and photoinitiators. These photoinitiatiors are activated by the UV light to link monomers & oligomers together and create a corresponding network of polymers. The formulation is then almost instantly cured or hardened in a short period of time.
UV LED lighting systems in the UV-A range (365-405nm, depending on the chemistry) are widely used for high-speed curing processes thanks to great intensity and electrical efficiency. Precise, compact & innovative LED lightings often replace old, huge & energy-consuming thermal curing or mercury lamps in a wide range of industrial processes.
- Example of Applications -
UV-LED Screen Printing for Industrial Printing
UV-LED screen printing is an industrial printing process that uses ultraviolet curing technology to instantly polymerize inks on a wide range of materials, including plastics, glass, metal, textiles, wood, and packaging. Thanks to UV-LED technology, inks cure uniformly, without solvents and without waiting time, ensuring excellent adhesion, high print resolution, and consistent quality. UV-LED screen printing systems are used in demanding production environments, increasing productivity, reducing energy consumption, and contributing to the sustainable optimization of industrial printing processes.
UV Conformal Coatings for Electronic Assembly Protection
UV conformal coatings are technical protective coatings applied to printed circuit boards and sensitive electronic components. This technology provides a reliable barrier against moisture, corrosion, dust, and thermal stress, thereby enhancing the lifespan and performance of electronic systems operating in demanding environments. Thanks to rapid UV-LED curing, the coating polymerizes evenly, ensuring a uniform layer and consistent protection of electronic circuits. Recognized for its industrial efficiency, this protective solution helps improve equipment reliability while optimizing manufacturing processes.
UV Potting for Electronic and Technical Components
UV potting is a protection process for electronic, medical, and optical components based on the use of ultraviolet-curable resins, enabling fast, precise, and fully controlled polymerization. This technology ensures reliable protection of encapsulated materials while providing excellent mechanical, chemical, and environmental resistance, essential for demanding technical applications. Thanks to industrial UV-LED solutions, production cycle times are reduced, assembly quality is improved, and process repeatability is enhanced.
UV Crosslinking of Resins, Adhesives, and Polymers
UV crosslinking is an industrial photopolymerization process used to improve the mechanical, chemical, and durability properties of materials through exposure to ultraviolet light. This technology is used for curing resins, adhesives, inks, coatings, and engineered polymers, ensuring rapid, uniform, and energy-efficient polymerization that meets the requirements of modern manufacturing processes. Thanks to industrial UV-LED systems, precise control of irradiation intensity and wavelength enables optimization of crosslinking quality and process repeatability.
High-Speed UV-LED Printing for Industry
High-speed UV printing is based on UV LED curing systems that enable instant drying of inks directly on high-intensity industrial production lines. This UV curing technology is widely used in digital printing, offset printing, flexography, and inkjet printing, where it meets the demands for speed and precision of modern production processes.
