 INTRODUCTION AND GENERAL CONSIDERATIONS In the process of joining two parts by means of anadhesive, theadhesive must at one, tirne'exist in the liquid state between the twosurfaces in order to properly wet them. Subsequently, the adhesive'mustbe solidified to impart strength to the bond. This can be donein many different ways:In solvent

By Jean-Pierre Fouassier - Labatoire de Photochimie GénéraleRadTech Europe Conference 1989Radiation curing is, nowadays, a well-established technology which develops and grows rapidly on an industrial scale. Originally, the most emergent applications were related to the UV-curing of coatings. Reprography (printing plates, integrated

By Helmut G. Gaube, Juergen Ohlemacher - Degussa AGRadTech Conference 1989Exterior clear coatings based on cationically UV cured epoxy formulations offer product advantages over UV acrylate systems in food packaging applications including low residual odor. This paper presents analytical results from migration and extraction tests fo

By P.J. -M. Manus, Union Carbide Europe S.A. - RadTech Europe Conference 1989Cationic UV initiated polymerization is now a well established technology in the radiation curing market. Distinctive properties of cationic UV initiated polymerization include rapid cure response, absence of oxygen inhibition, post cure effect and high

By Aldo Priola, Giuseppe Gozzelino, Universita di Messina, Politecnico di Torino - RadTech Europe Conference 1989In this work the influence of irradiation and curing conditions on some properties of UV cured films was investigated. As starting materials two types of acrylic products, namely bisphenol-A-dihydroxyethyl-diacrylate and b

Zapf, Siemens AG - RadTech Europe Conference 1989Details of newly developed photo-patternable solder masks based on polyether resins with photo-crosslinkable side groups are reported.The synthesis of the basic photopolymers follows a chlorine-free route by addition of olefinically unsaturated isocyanates

By Alice H. Pincus, Pincus Associates - RadTech Europe Conference 1989The use of UV and EB technology for curing coatings and inks has been commercial in the US for about 20 years now and has grown steadily, although slower than anticipated, during that time.However, radiation cured coatings, inks and adhesives still make up a very s
