There are a lot of UV sources commercially available that can be used for curing.Depending on theprinting and exposure application, different UV lamps are needed to adaptspectral distribution,process speed, thickness of the material to be cured etc. UVlamps are produced with lengths varyingbetween a few centimeters and four meters, specific electri

The use of cationic UV curing systems based on cycloaliphatic diepoxides continues to growin several applications, mainly within the rigid and flexible packaging sectors. Today'sdevelopment consists primarily in optimizing cationic formulations in order to meet more stringentend use requirements. The kinetic of photoinitiated cationic polymerizatio

UV-cured coatings are extensively used and the variety of substrates on which they can be applied is growing up. A good knowledge of the wetting characteristics of these substrates is necessary toachieve properties such as coating adhesion, printing, pigment dispersion and cleaning. The wetting behaviour is controlled by the surface tension of both

Over the past two decades, the production of plastics throughout the world has more thandoubled1. The advantages of using plastics are their light weight, corrosion resistance, ease ofmanufacturing, and the wide range of dynamic and mechanical properties that can be obtaineddepending on the nature of the plastic. However, all plastic substrates suf

Radiation-cured coatings comprise one of the so-called 'hightechnology' techniques which are basically concerned with high-solidstechnology, the main processes having been developed to such a degreethat several lines using these techniques have been in commercial usefor many years. The other 'high tech' processes include water-bornesystems, high so

Radiation-curable materials are primarily used in a limited number of "traditional" applications, the most  important applications areas being graphic arts, wood coatings, adhesives, and electronics. In these applications, full use is made of the specific advantages of radiation-curable materials, which include the high production speed and th

Ever since the first industrial application of UV curable systems there has been the justified wish to be able to quantitively evaluate the production success, and thus the product quality achieved, in real time during or immediately after termination of the production process. However, quantitativemeasuring of the degree of curability still involv

UV curing is growing at a remarkable rate in many manufacturing areas, automotive is no exception. The UV curing process is making its way into many areas of assembly and decorating for automotive trim and body applications. What is driving the interest in UV curables in the world wide automotive market? One of the main concerns is volatile or
