Direct and indirect methods for the Characterization of photoinitiator efficiency

By J.Ohngemach, M. Koehler, G. Wehner, E. Merck - RadTech Europe Conference 1989This paper presents the results of an in-depth investigation of the reactivity of photocurable systems consisting of acrylated monomomers/oligomers and photoinitiators by using Photo Differential Scanning Calorimetry (Photo-DSC) . Thus, photoreactivi

An evaluation of different photopolymerizable systems with particular reference to their water dispersions

By R. Cavalieri, S. Farronato, C. Settin, Hoechst Sara S.p.A. - RadTech Europe Conference 1989The current state of UV curing technology is taken into account, particularly from the stand point of energy cost and pollution. As an ideal end—point, some unsaturated, UV curable binders in aqueous dispersion, are proposed and a speci

overview and trends in radiation curing technology 1989

By Ronald Golden, Radcure Specialties, Inc. - RadTech Europe Conference 1989 A brief summary of both free radical and cationic radiation curing chemistry is provided. Historical reasons for the rapid growth of this technology are reviewed, and a number of recent and emerging applications are discussed.It is shown that the techni

surface modification of plastics to high intensity ultraviolet light

By William R. Schaeffer, Fusion UV Curing Systems - RadTech Europe 1989This paper investigates the use of high intensity ultraviolet energy employed in conjunction with altered spectral output to accomplish surface modification of a plastic to enhance adhesion of an ink or a coating in an efficient, safe and economical

Heterogeneous Initiation in Photochemical Processes

By M. Koehler, J. Ohngemach, E. Poetsch, E Merck - RadTech Europe Conference 1989 Covalent photoinitiator fixation on silica transfers the photoactivity to the solid surface. The dispersion of the initiator modified material in a monomer solution forms a heterogeneous photopolymerizable system. A microcoating of the particles becomes

Syntheses and application of water soluble photoactive polymers

By 0. Nuyken, B. Volt, Lehrstuhl für Makromolekulare Chemie I - RadTech Europe Conference 1989The synthesis of water soluble azo compounds and their photochemistry in water and ethanol solution is described. The trans—azosulfonates are perfectly stable up to 200 °C.However, they decompose at room temperature after transformation into

UV Mirror Backing System

By James Graham, PPG Industries - RadTech Europe Conference 1989A new and novel use for a UV curable coating on mirrors is presented, showing its advantages and parameters. The process is commercial in the U.S. and France and is patented in the U.S. with an application pending with the European patent office.

UV/EB Curable Laminating Adhesives

Morris A. Johnson & F. Kurt Willard, Radcure Specialties, Inc - RadTech Europe Conference 1989A variety of UV and EB curable acrylate-functional oligomers and monomers of different types were tested in several formulations to show potential for use in laminating adhesives. Substrates were clear and opaque films of comme
