In recent years UV equipment manufactures have responded to the challenges presented by the use of thinner films in the label and packaging industries and the heat management issues that needed to be addressed to permit successful printing quality to be achieved. Continued profit pressure from 'end users and retailers is driving the supply chain in

UV curing systems for industrial applications have been in use for the last 12 years, mainly forflat surfaces in the furniture and flooring industries. Solvent free (100% solid) lacquers areused in these applications and are traditionally applied by rollers. In the last few years, new UV lacquers have been developed that permit more complex 3- dime

Photo-induced acid-catalyzed crosslinking systems have been widely studied by many workers 1].The highly sensitive photocrosslinking materials can be used as negative-type photoresists, coating materials and printing materials. Epoxy/phenolic novolac blends are one of the most useful thermosetting systems which are also known to be cationically or

The mechanism for creating matt effects in traditional coatings is well understood in that it relies on incorporating a particulate matting agent in the coating and adequate film shrinkage resulting from evaporation of volatile components enables the particulate to create a microrough surface. Specially designed matting agents are avà i/able, exemp

Photo-cationic polymerization based on photo-generation of acid from onium salts induced byUV light and consecutive cationic polymerization initiated by the generated acid was first proposed in 1970's." Since then, photo-cationic curable materials, using cationic polymerizablemonomers such as epoxides and vinyl ether derivatives, have been widely A

The quality and performance of polymers are critically linked to the cure characteristics of the polymerization system. Improvements in monomer curing efficiency would allow optimum polymer properties to be achieved with minimized irradiation times and intensities, which has significant industrial relevance. The development of monomers that exhibit

 Pressure sensitive adhesives (PSAs) are widely used in the industrial application and in our daily life, such as packaging, labels, tapes, and so on, because of their excellent characteristics - easy to stick to many kind of substrate without any activation, and easy to peel. Among many kind of PSAs, solvent-borne or water-borne acrylic PSAs

The transfer molding process used to encapsulate semiconductor devices suffers from significantproblems due to the high operating temperatures and high pressures required to fill the mold.  These aspects of the current process can lead to incomplete mold filling, thermal stresses, and displacement of the fine wires that provide electrical inte
