Glass fiber reinforced, or composite plastics are attractive alternatives to conventional sheet metals in automobile construction. The common Sheet Molding Compound (SMC) is the main example. It is composed of an unsaturated polyesters with additives, mineral extenders and the glass fibers. The use of this material has fluctuated as the automotive

It is not since today that we know the application of UV-curing under oxygen-reduced, inert conditions. For the cross-linking of silicones manufactured by Goldschmidt it is imperative to keep the residual oxygen content below 50 ppm. Particularly by the end of 1999, the demand for UV units running under oxygen-reduced conditions increased for the f

UV curable silicones are a highly specialised class of compounds that is known in the industry for more than 17 years: UV curable silicones can be applied as release coatings on paper and plasticsubstrates. Typical applications for the compounds presented in this paper are release coatings for self adhesive labeistock, which accounts for approx. 70

  UV powder has the potential to be one of the most important powder technologies for the future. After several years of development efforts it has been possible for DuPont Powder Coatings tocommercialise the UV powder technology in Europe. From the very beginning in 1993 we believed in the so we worked on the project until we were succes

Improvement and further growth of radiation cured coatings in exterior applications dependson the development of inherently better performing binders. For the building and automotiveindustries these binders should combine excellent weathering performance with other moreand more stringent requirements. An understanding of coating degradation is a fi

 Vinyl ethers are known as non-irritant reactive diluents for UV-curable formulations. In acrylate based systems they could replace monomeric acrylates providing better diluting properties in combination with higher 1 However, subject of this study will be blends of epoxides together with vinyl ethers. Also in these systems the viscosity of th

The move towards lower VOC emission from paint systems can be achieved by using water-based coatings. In this case film formation requires a low glass transition temperature, Tg, while most applications require a final high Tg and high solvent resistance. Light induced curing is an interesting way to overcome the contradictory demands on 1g. While

Innovative ideas may result from assiduous individual brainwork but mostly emerge from the organized or incidental exchange of thoughts between individuals with expertise in specific fields. Such a synergistic idea generation approach promises highest return in a world where specialization often comes with estrangement even from related subjects. I
