The organic coatings used for outdoor applications, should be protected against the harmful solar radiation to overcome the photodegradation resulting in changes in optical and mechanical properties of the coating. The photostabilization can be improved by adding UV stabilizers to the photo-curable formulation: UV absorbers and Hindered Amin Light

Traditional medium pressure mercury lamps produce a wide spectrum of radiation,including significant emissions in the ultra violet region, specifically UVC, UVB, UVA andUVV. This spectral breadth allows for the selection of photoinitiator(s) to optimize thecure of acrylate-based inks, coatings, adhesives, sealants and composites according tothe typ

As the number of applications of visible light-induced photopolymerizable materials increases, the need of development of efficient PIS for the visible becomes more and more evident. Some of the applications of this technology are dental materials, laser imaging, and holography [1-4].LED sources are commercially available in a wide variety of wavel

industry, this energy transfer effect was first put to good use in the 1980’s when it was found that small additions of 2-isopropylthioxanthone (ITX) could increase the cure speed of theaminoalkylacetophenone photoinitiators such as 2-methyl-4’-(methylthio)-2-morpholinopropiophenone (MMMP) by a considerable degree 1, 2. Since then, these

The advent of digital inkjet printing techniques about 30 years ago, announced a new era at first in small scale office and home printing, further has emerged in industrial scale printing in a large variety of wide and super wide format applications and is now being rolled out in even more exciting applications ranging from high speed document prin

The use of energy curing technology in graphic arts is still marginal, even if it has all thecharacteristics to become a very important technique mainly for high printing speed, increasing quality, reduced VOC release. In order to develop these characteristics and to satisfy unmet needs, a continuous improvement of the components of the formulation
