EBhärdning

EBhärdning, also known as electron beam curing or radiation curing, is a process used to solidify or cure inks, coatings, adhesives, and other materials using a focused beam of electrons. This method offers rapid curing times compared to traditional thermal curing or UV curing. The high-energy electrons interact with the material's molecules, initiating cross-linking reactions that transform the liquid into a solid state almost instantaneously.

The EBhärdning process typically takes place in a vacuum chamber or under an inert atmosphere to prevent oxygen inhibition and to protect the electron beam source. The depth of penetration of the electron beam depends on the energy level of the electrons and the density of the material being cured. This makes EBhärdning particularly effective for thicker coatings or materials that are opaque to UV light.

Key advantages of EBhärdning include its speed, low energy consumption, and the absence of volatile organic compounds (VOCs) in many formulations, making it an environmentally friendly option. It also provides excellent scratch resistance, chemical resistance, and durability to the cured materials. Applications are found in various industries, including printing, packaging, wood finishing, and electronics manufacturing. The technology requires specialized equipment and safety protocols due to the nature of the electron beam.
