A new generation of electron beam accelerators that operates in the 80 kV — 110 kV range hasbeen developed. This will enable users to obtain all of the benefits of electron beam curing,while eliminating several drawbacks. Electrons accelerated at these low energies are bestsuited for surface treatment. Energy deposition is maximized in the top 5 to

The objective of this work is the evaluation of the potential use of acrylic colloidal silica in the EB orUV curing of transparent coatings for OEM (Original Equipment Manufacturer). Formulations basedon HDDA, TPGDA, aliphatic urethane triacrylate containing acrylic silica organosols of 25 and 50nanometers size were EB or UV cured over PC (polycarb

Cationic UV curing systems based on cycloaliphatic epoxides are well known for coating ofmetal and plastic substrates. The formulation of epoxides together with commercially availablevinyl ethers have the potential to further enlarge the applicability of cationic radiation curablesystems. Lower viscosity, faster cure rate and higher solvent resista

Powder coating curable by ultraviolet light represents a new coating technology combining manyof the advantages of thermosetting powder coating and liquid UV cure coating technology. Incontrast to thermosetting powder coatings, melting and curing of UV powder coatings are twoseparate processes. Upon exposure to heat, UV curable powder coatings melt

UV irradiation for technical applications is mainly used to cure different coating materials. Practicalexperiences have shown us, that there are more applications for UV irradiation other than just curing. There is an interesting number of installations using UV light to activate polymer surfaces, but it seems to be difficult to predict the results

Rolling is an extremely efficient coating method by which (relatively) thin, uniform layers can beapplied with an application efficiency of around 95% and economical use of the material. Thismethod is consequently used in a whole variety of surface treatments. It is used, for example, forcoating endless metal coils — the so-called coil coating — as

The Danish banknotes are like most other banknotes printed with offset and intaglio printing. Theoffset is the background consistent of fine lines. The portrait, the rosette, the latent image and thedenomination in words are all printed in intaglio. Contrary to the majority of banknote printers who print their banknotes in sheets the Danmarks Natio
