IntroductionThe photoinduced polymerization or crosslinking of vinyl andepoxide based monomers have gained importance in recent yearsdue to the many possible applications of these processes Suchapplications include microelectronics /1/, surface improvement/2/, information recording materials /3/ and printing plates /4/.In many cases the polymer for

INTRODUCTIONModern production facilities are increasingly characterised byprocess economics, air. pollution . control and enhancedperformance. In.recent years U.V. light curing adhesives havedeveloped significantly increased awareness and acceptance. Thisis due toseveral important advantages overconventional adhesivesystems.

Cationic UV-curabl e clear coatings based on epoxy formul ati ons used forexample as overprint varnishes have been commercially available for several.years. These coatings have received acceptance mainly because of theirodourlessness which makes them ideally suited for applicationswhere odour would otherwise present a major drawback. These applicat

INTRODUCTIONThe development of radiation processing using electron accelerators requires goodcontrol of the treatment parameters which improves the dosimetry quality. The analysis of theshape of the scanned electron beam is of prime necessity. A Multiwire Beam Shape Analyser(MBSA) has been developed by AERIAL (Association d'Etudes et de Recherches

IntroductionRadiation Curing Technology is a fast growing part of thechemical industry. In recent years we have seen a strongimprovement of technology and development of new chemicalcomponents for radiation curing formulations:Acrylate Monomers form an essential part of most radiationcurable formulations. This paper gives you an overview of themark

INTRODUCTIONLasers are being increasingly used in polymer science due to the distinctadvantages of these powerful sources of radiations. The spatial coherence of thelaser emission provides a great directivity, which permits one to focus the laser beamdown to a submicronic spot. The temporal coherence of the laser emission, whichoccurs at a well-def

IntroductionTrimenthylol propane triacrylate (SR-351) has been the majormultifunctional acrylate monomer used in ultraviolet light curedcoatings and adhesives since the late 1950's. Multifunctionalacrylates are used to lower viscosity, increase rate of cure,provide solvent resistance, and impact resistance in a wide varietyof coatings.Trimethylol p

INTRODUCTIONRecently in the paint and printing ink fields resins which cureby exposure to high energy radiation are becoming more widelyused.These resin systems have many advantages such as fast curing,fine patterning due to easy masking; improved dimensional stabilitydue to low temperature curing; they contain no solvents thuseliminating environme
