Termination in Photopolymerization of Methacrylic Monomers Using FTIR and EPR Spectroscopy
              There are three primary reactions that define a polymerization: initiation, propagation, and termination. Of these three, the termination reaction is the aspect of crosslinking polymerizations that is least understood and of utmost importance to the properties of th
Photopolymerization Kinetics in Polymer / Liquid Crystal Composites
This manuscript focuses on our recent work involving photopolymenzations of monomers in a liquid crystalline environment. In particular, this effort concentrates on understanding the influence of a liquid crystalline medium and monomer segregation on polymerization kinetics and polymer structure. These studies are of considerable importance for pol
A Novel Low Odour Photoinitiator for Dark Pigmented Systems
 A new class of bifunctional photoinitiators that contains in the same molecule differentphotoinitiating moieties has been developed. The best candidate of the class, LFC 1001, ischaracterised by high efficiency in radical polymerisation of acrylic coatings. The photoinitiator isparticularly suitable for UV curing of dark pigmented inks. One o
A Novel Way Of Characterizing Photocrosslinked Systems
In this study, a photocurable system which contains dimethacrylated anhydride as a crosslinkerwas characterized. 2-Methoxyethyl methacrylate and methacrylic anhydride were photopolymerized in bulk to obtain a crosslinked network that maintains hydrolyzable anhydride linkages. This material provides the opportunity to degrade the crosslinks and obta
Adequate Protective Gloves for Working with UV/EB-Curing Acrylates
   UV/EB-curing acrylates are highly reactive. This is what makes them to cure rapidly.A possible side effect is that these products may cause skin irritation reactions in certain persons when they come (frequently) in contact with the skin. This is why in Safety Datasheets of these products as well as the formulations containing the
Possilbilities of Three-Dimensional Curing of UV-Curable Clear Coats in Car Body Finish from the Viewpoint of a Coating Equipment Supplier
After the clear coat paint evolution of the last years that had the major target to drastically reduce the solvent emissions (figure 1), the employment of UV curable paints for car body paint application is being discussed increasingly.The employment of UV curable paints has numerous advantages, such as:o improved product quality,o increased produc
Further Studies on Photoinitiator Blends
The present studies mark a breakthrough in photoinitiator development, in the sense that, under appropriate conditions, an abstraction type initiator shows a higher curing efficiency than a cleavage type photoinitiator. The studies reveal a remarkable discovery in the field of ultraviolet curing, viz., a synergism between maleimides and benzophenon
UV Flexo: a Cost Comparison Evaluation
This study evaluates the economic impact of different technologies in the field of graphic arts.The comparison has been carried out between UV flexo printing and1. conventional sheetfed offset printing on carton board2. UV rotary letterpress printing of self-adhesive labels3. solvent based flexo printing for flexible packaging.Conclusions are drawn
