INTRODUCTIONEpoxy resins are used in many assembly processes of electronics for the mounting orencapsulating of components and modules. The resins should process easily and curerapidly at moderate temperatures in order to attain short cycle times, tolerant manufacturingprocesses and low thermal stressing of substrates. These demands generate thehig

IntroductionRadiation curable products are widely used.For some of these applications (f.i. overprinting varnish) the main requirements, for thefinal coating are to be tackfree, hard and solvent resistant.Recently the variety of applications where radiation curing is used, has strongly increased.Coatings with extremely high performance and ultra fa

 INTRODUCTION   UV-curing in the screen printing industry belongs to a lot of factors which must be done to get the best results. The description of the materials like gauze, stetchingof itself, stencil materials and its automatic coating, squeegues, machines anddryers is very important. The selection of it all must be very

IntroductionThe epidermal and handling properties of medical tapes are mainly controlled by the degreeof crosslinking in UV-curable acrylic PSA. Generally an enhanced UV-irradiation dose leadsto reduced adherence to the skin (fig. 1). On the other hand a low curing level is associatedwith a low cohesion which finally results in an unacceptable mass

INTRODUCTIONPhenol and phenolic compounds are commonly found at low concentrations in naturalwaters. However, at the high concentrations found in some industrial wastewater dischargesand agricultural activities (1-3) phenol may be toxic (4). Phenol is also one of the mostfrequently found organic compounds at Superfund sites (5). Many treatment meth

INTRODUCTIONUV technology involves curing a liquid resin within seconds after application of UV light.The rapid cure response of these conformal coatings offers many advantages over theconventional coatings as illustrated in Table 1.UV cure is a cool process. There are no run away exotherms that are often found inconventional systems. A rapid cure

INTRODUCTIONUV curing is generally recognized to offer a number ofbenefits and advantages over the use of conventional, orsolvent—based materials. Some of these benefits can bedirectly related to cost while others are less tangible, andrelate toproduct performance, quality, durability, or safety,for examples. Both tangible and intangible factors ar

INTRODUCTIONGrowing concern about the environment and rapidly dwindling waste disposalspace make reduction of waste a necessity. Therefore, the recycling of plasticcontainers is being persued with increasing intensity and, in that context,the labels used on plastic containers must be taken into consideration aswell.
