State-of-the-art technology today stands for bonding as the joining technique in construction andconnection technology for fibre and integrated optical sensors. Therefore, mainly commerciallyavailable adhesive systems are used.The task for fibre-chip-coupling was to develop a suitable adhesive system to fulfil the specialrequirements of coupling th

A new generation of low cost electron beam dryers operating in the 70 kV — 110 kV range is nowcommercially available. Electrons accelerated at these low energies are especially suited for curingsolvent-free inks, coatings and laminating adhesives that contain no photoinitiators. The new electron beam (EB) dryers are very compact, allow high process

The paper will present the status and future direction of UV refinish for the auto repair industry in North America. The paper will present the resufts of market research performed in the refinish industry, as well as the consensus of the various raw material, formulators and equipment suppliers to the industry. The paper will survey the commercial

The dual-curing of an isocyanate functionalized polyurethane-acrylate, associated to an alcohol, was investigated by infrared spectroscopy to address the issue of the curing of coatings in shadow areas on three-dimensional objects. The thermal polycondensation was followed through the decay of the isocyanate group and the photopolymerization throug

Electron beam curable flexographic inks have recently been introduced to the flexible packaging market. The new EB ink system offers the benefits of UV curable inks—like good print quality, high gloss and product resistance—while eliminating needs in interstation curing. The system has an efficient cure response that allows for complete cure with l

EB/UV curable technology has been known for many benefits including zero-VOC, production speed enhancement, overall cost reduction, and processing enabling capability. Recently, with the help of comprehensive and FDA compliant migration determination testing protocols, EB/UV chemistry has emerged as one of the mainstream chemistries for food packag

Ink Jet printing is now available for color printing in High Definition with UV inks on different kinds of media such as glossy papers, plastics, glass, wood or metal. We shall make a first overview of the present digital technologies: Ink jet versus others technologies such as Thermal Transfer- DyeDiffusion and liquid toner methods.. We shall pres

For years radiation curing lacquer systems have been broadly accepted in industry because of their environmental friendly and economical advantages. Important applications like coatings for furniture and packaging have a need for matt surfaces. So it is a challenge for the coatings industry to offer matt 100% UV systems with the same application an
