The development of a flexible electron processor has been necessary forthe validation of its use in the sterilization of a variety of containergeometries (1). A.250 kV selfshielded accelerator used for this purpose,which provides a 30 cm wide beam at currents to 20 ma: is shown in Figure1. The ability to separate the electron source from the lower,

Web offset printing using electron beam (EB) drying is believed to provide an efficientalternative to heat-set web offset using thermal drying. Some of the potential advantages ofthat non conventional printing/drying technology are- the use of solventless, 100 % reactive printing inks,- the dramatic reduction of the emission of volatile organic com

The development of self-shielded electron processors in the seventies,suitable for unrestricted use in the industrial environment, has led to avariety of new commercial processes/applications utilizing these efficientsources of ionizing radiation. The growth of the industry in the past twodecades has followed a pattern of broadly diversified applic

In view of ever-rising waste amounts in all highlyindustrialized countries, the need for an intensifiedrecycling of used paper has been reinforced by acutewaste disposal problems. Actually, the paper industriesof most developed countries can look back onmany decades experience of recycling. Within thecountries of the European Community, recycledfib

Today, radiation curing (RC) is a widely used technique for a number of industrial processes. Examples are woodfinishing, printing inks, metal coating and embedding of electronic materials. Additionally, there is a well established and still rapidly growing field for râdition curable systems in the manufacturing of silicone release coatings. This i

There has been a growing interest in recent years in light-induced cationicpolymerization, due to the development of very efficient photoinitiators and highly,reactive new monomers. A distinct feature of cationic polymerization is that a largevariety of monomers which are inactive towards radicals, like epoxides, cyclic ethers,vinyl ethers or silox

IntroductionTwo years ago, we set up a study [1] in an attempt to correlate polymerizationshrinkage with adhesion on substrates. The work was carried out onABS and steel. Establishing a correlation between either shrinkage or. surface .tension and adhesion seemed to be a very difficult thing, based on the limited datawe had at the time. Let us remi

IntroductionElectron beam equipment manufacturers have endured a business slowdownsimilar to that experienced by capital equipment manufacturers in general as aresult of the world wide economic recession. The unhealthy economic climatecaused potential users to defer their equipment purchases and suppressed theanticipated increase in new installatio
