Since the early nineties, water-based radiation curing technology has enjoyed an uninterrupted growth in the field of industrial coatings and this trend is expected to continue in the coming decade and to expand into new markets such as printing inks or field applied coatings. The major factors fuelling the growth of water-based radi

Pigment dispersion resins for energy curable inks require excellent properties for pigment wetting, pigment dispersability and high pigment loading. In this study, two new polyols were developed, acrylated and evaluated in energy curable ink applications. These polyols have low viscosity handling ease and biorenewable content. Pigmen

A new generation of small highly compact e-beam emitters with an accelerating voltage range of 80 to 200 kV and treatment widths of up to 60cm is described. The new e-beam equipment features a sealed accelerator tube making vacuum pumping unnecessary. First applications are in surface sterilisation and in an e-beam laboratory unit.&n

A novel photochemical means to convert acrylate monomer emulsions into polymer latexes has been explored using radical miniemulsion photopolymerization. Our aim is to offer a complete overview through a stepwise mechanistic investigation. This talk will address first the electronic excitation of the photoinitiator in monomer miniemul

A Holistic View on Consumer Health and Safety Regulations for UV/EB in Europe.

Matting of transparent coatings is commonly achieved using porous inorganic matting agents with high surface area and oil absorption, and a particle size in the range of 5-15μm. These materials are extremely effective in solvent-based coatings where evaporation and shrinkage during drying and curing forces the particles to protrude f

The use of electron beam curing (EBC) for printing inks and varnishes, particularly in the (food) packaging industry is growing rapidly. Ecology and economy are the driving forces. An important, if not a key contribution, to this growth are low voltage EB systems. It has only been about 5 years since the first low voltage EB equipmen

UV-curing polyurethane dispersions are well established waterborne resin raw materials. Although very versatile in many different applications they have to be synthesised and thus delivered in an excess of water reducing the degree of formulation freedom. In this paper alternative concepts of water-compatible resins are presented tha
