UV curing adhesives now have an established share of the adhesive market 1,2]. A distinction is made between radical curing systems, most of which are based on acrylates, and cationic curing systems, which are mostly based on epoxides 3,4]. These adhesive systems are widely used in the electronics and microelectronics industries and for bonding gla

Both silicones and nanosized alumina particles can be used to improve certain mechanical properties (hardness, scratch resistance) of UV-crosslinking wood varnishes. However, selected combinations of both additive groups show much greater effects together, than the individual additives alone. Effective dosage levels and various combination ratios o

Curing of UV coatings on complex three-dimensional parts in an automotive production environment is a significant challenge. Factors such as productivity, part design, part size, and physical process constraints, and are a sampling of constraints that must be taken into consideration for UV process design and implementation. This paper will discuss

An EB flexo wet-trapping concept and liquid EB curable inks have been recently introduced to the packaging market. The features of the original prototype formulations have been refined in the new compositions, featuring improved theology and adhesion to a broad range of plastic films. The theological adjustments, along with improved design of the i

The sensitivity of organic coatings to scratching, abrasion and chemical attack can by significantly reduced by using UV curable monomers containing concentrated suspensions of inorganic nanoparticles. Commercial monomers containing up to 50% colloidal silica nanoparticles have been used to make UV nanocomposite coatings. The properties of multi-la

The development of new EB curable flexo inks than can be printed wet-on-wet, opens entirely new possibilities for the manufacturer of Cl-fiexo presses as well as for the producer of flexible packaging. With the elimination of interstation drying, replaced by one "cold" electron beam curing process at the end of all printing stations, there will be

Since the beginning of digital printing (early 90s), Xeikon has played an important role in introducing the first high speed digital color presses. In this early phase, the majority of the printed jobs were short run jobs, replacing traditional offset workflow. At the end of the century more variable data jobs were printed and at this moment nearly
