Characterization of unreacted residues in UV and EB varnishes

By S. Peeters, RadCure Specialties - RadTech Europe Conference 1989Purity and the possibility of making UV and EB coatings with very low levels of extractables is becoming more and more important. The influence of the photoinitiator systems and the structure of the products on the purity of the UV-coatings was studied. It was shown that v

urethane acrylates: expansion of radiation curable epoxy acrylate coatings

By Henry C. Miller, Sartomer - RadTech Europe Conference 1989Urethane and epoxy acrylate resins have been the backbone of radiation and electron beam cure coatings for over twenty years. Aromatic urethane acrylates have beendeveloped that bridge the epoxy acrylate properties. Liquid color, thermal storage stability, solvent resistanc

Concurrent cationic/free radical polymerization of vinyl ethers with acrylate functional oligomers

By F. J. Vara and J.A. Dougherty, GAF Chemical Corp. - RadTech Europe Conference 1989An alternative to the use of acrylate monomer diluents is described. The use of vinyl ethers as diluents for acrylato oligomers in the concurrent cationic/free radical polymerization is demonstrated. Both urethane acrylate and epoxy oligome

UV curable pigmented systems: available photoinitiators and current trends

By Giuseppe Li Bassi, Fratelli Lamberti S.p.A.Pigmented coatings and filled or reinforced plastic systems are very widely used for functional and decorative purposes. The possibility to enter these fields with 1W curing technology offers many practical advantages.The proper choice of the photoinitiators combination which meets the&nb

An overview of the role of UV-curing in imaging

By Averil Horton, Cookson Group plc - RadTech Europe Conference 1989The aim of this paper is to provide some insight into the role of radiation curing in imaging. This requires an understanding of the basic concepts of imaging which are selective exposure, positive and negative systems, image and non—image areas, and developitent.The

Study on the EB cured resin stamper for embossed hologram

By Y.Inaba and S.Okano, Technical Research Institute Toppan Printing Co. - RadTech Europe Conference 1989Electoron beam curing technique has been studied in manufacturing resin stampers for embossed holograms. Several EB curable resins were tested and evaluated from measuring diffraction efficiencies of holograms embossed with these

New microwave energized uv systems

By R. W. Stowe, Fusion UV Curing Systems, RadTech Europe Conference 1989The number and variety of applications for UV curable adhesives, coatings and inks have been increasing at a rapid pace. 'New demands on lamp systems arise from requirements for higher speeds, higher efficiency and special configurations for complex par

Furniture Finishing with Radiation Curable Coatings - The "Eastern European Style"

By Peter G. Garratt, Reichhold Chemie GmbH - RadTech Europe 1989Although the furniture industry in Eastern Europe has not yet reached full maturity, neither technically nor capacity-wise, the ultra-violet curing technology has become firmly implanted in furniture finishing processes in the Soviet Union and various other COMECON count
