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

For packaging applications involving food or beverage, food safety is very important. In analogue printing technologies, UV-curable inks are used for indirect food contact applications. These UV curable low migration (LM) inks are typically based on using multifunctional polymerisable compounds and photoinitiators with a relatively h

The termination mechanisms occurring in a UV-powder coating system during photopolymerization process are investigated and compared to a conventional acrylate monomer system. First, the photoinitiator concentration, viscosity and conversion of the monomer effects on the termination reaction occurring in photopolymerization of a
