Reinforced clear coats were prepared using nanosized silica and alumina particles in UV/EB curable acrylate formulations. For a firm embedding of the oxide nanofillers via covalent bonds to the network acrylates their surfaces were modified by polymerization-active trialkoxysilanes, e.g., methacryloxypropyltrimethoxysilane and vinyltrimethoxysilane

One of the most important challenges these days for the Industrial Wood Finishes manufacturers is the development of new products which have to be compliant with the new regulations concerning VOC emissions. This target is especially difficult in the case of certain applications in which alternative technologies have problems to achieve the usual s

A new type of environmentally friendly, Novel low viscosity, solventless epoxy compositions have been developed for coil coating appilcations. The coatings can be cured on a high speed, low dose electron beam production ilne. Coatings can be clear or pigmented, used for both indoor and outdoor on metal, glass, plastic or wood surfaces. Alternativel

There are two UV curable silicone release systems on the market. Both are solventless and produce release coatings without the use of heat, but differ by their underlying chemistries. One is based on silicone acrylates and cures via a free radical mechanism, while the other release system uses epoxy silicones and cures in the presence of cationic i

For several years DuPont Powder Coatings has been producing and selling UV curable powder coatings for commercial use on MDF furniture and PVC flooring, and in doing so offering unique advantages to our customers. Our continuing work aims to further expand the UV powder technology with new and better formulations for our customers. Applications wit

The UV/EB Acrylate Resins Sector group of CEFIC has created a guide to the classification andlabelling of UV/EB Acrylates. This guide is a direct response to the voluntary commitment of thechemical industry to improve continuously in all aspects of health, safety and environment, theperformance of its processes and products and to communicate openl

The increased pressure to reduce VOC levels in surface coatings and the constant improvements required in coating properties continues to drive the growth of UV technology. The dispersion and stabilisation of pigments in such systems can be problematical. Often the oligomer and monomers employed in the formulation do not provide satisfactory pigmen

 Maleimide functional oligomers (MIRO) have been synthesized and evaluated as photoinitiating oligomers. Preliminary formulation work was performed in comparison to an acrylated photoinitiator and a benzophenone/tertiary amine package in a standard overprint varnish. Results for this work will be presented and discussed.
