A novel photoinitiator for modern technology
By L. Misev, V. Desobry, K. Dietliker, R. Hüsler, M. Rembold, G. Rist and W. Rutsch, CIBA-GEIGY Ltd. - RadTech Europe Conference 1989A new a-cleavage photoinitiator is presented. This initiator is especially useful in pigmented systems and in various applications of the imaging area due to its absorption characteristics in the r
Photoimageable Liquid Solder Masks with High Resolution Properties
By H. Ahne, W. Plundrich, 1. 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
How the United States market is gearing up for the 1990's
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
New multifunctional acrylate with extremely low skin irritation
By Joerg J. Wildi, Hans Rahn & Co - RadTech Europe Conference 1989Multifunctional acrylates have become important building blocks in radiation curable formulations. In- and tetra-acrylates of the first generation, such as TMPTA and PETA, in spite of being excellent products, have been increasingly replaced due to their high skin
Low voltage Electron Beam accelerators with high output
By Peter Holl, Eberhard Föll, Polymer-Physik Tübingen- RadTech Europe Conference 1989More severe environmental protection requirements having given way to stronger governmental restrictions for limiting the emission of noxious substances into the atmosphere (Technical Instructions! TI Air), determine the permissible limits for mass f
Effects of pigments on radiation curable coatings for metal
By C Lowe, Crown Industrial Coatings - RadTech Europe Conference 1989The difficulties encountered when attempting to obtain adhesion of radiation curable coatings to metal are well known. The effects of pigments on the extent and rate of cure in EB curable systems are less well documented, although it is qualitatively understood that
A comparison of thickeners in UV formulations
By Alice H. Pincus, Judith A. Goonyep, Pincus associates -RadTech Europe Conference 1989 Viscosity and rheology of formulations are of utmost importance for optimum application. In many UV formulations, the addition of a thickener is required. Described in this report is a comparison of the effectiveness of a variety of thickeners in raising the v
Photogeneration of Acid, Curing and Imaging Applications
By S. Peter Pappas, Polymers and Coatings Department North Dakota State University - RadTech Europe Conference 1989Curing and imaging processes, based on photogeneration of acid, have not as yet achieved the commercial significance of corresponding free radical processes. Several reasons for this may be advanced including (1) th
