Vinyl and glycidyl esters of Versatic 10 acid are well established building blocks for coating resins. They provide outdoor durability, hydrophobicity, chemical resistance, improve adhesion and viscosity reduction in a wide range of polyesters, acrylic and vinyl resins. Recently the acrylate ester of glycidyl versatate (ACE) has become available fo

UV/EB cationic curing is an alternative radiation curing technology circumventing some of the free radical polymerisation disadvantages like air inhibition and poor adhesion on difficult substrates. Nowadays a number of new commercial photoinitiators, monomers and co-resins suitable for such systems are available. It can be mentioned for example tr

Solid-state UV emitters promise to alter the discussion of how UV materials are cured in a manner similar to the way the microwave oven has transformed the way we talk about cooking. Just as a bowl of popcorn may look and taste identical when cooked either way, so will UV coatings look and perform identically whether cured with conventional medium-

Over the past years UV-technology has been adopted by the automotive industry via componentsuppliers. UV-curing processes of three-dimensional components are state-of-the-art in this sector, even for outdoor applications. The lecture describes the benefits of UV-technology and offers a survey about current applications on the market. Several system

This paper describes the challenges that UV curing inks and coatings still face before they can gainmajor positions in the flexible packaging market from the currently dominating solvent-borne and — to a lesser extent — water-borne formulations. Can food compliance requirements be met? Can the cost/performance gap against solvent-borne systems be r

High Performance Coatings (HPC) are typically applied as multi-layer systems by roller coatingtechnology and cured by ultra violet (UV) energy. The coatings are either micro- and/or nano-particle modified acrylated resins, which yield extreme hardness resulting in high mechanical resistance to scratch, impact and abrasion. Depending on the degree o

The advantages and performance properties of Electron Beam (EB) curable laminating adhesives have been previously ° The most significant advantage is that full bonding is achieved instantly upon EB irradiation. This allows immediate slitting, shipping, heat sealing, and filling of the package. One challenge with instant bonding is that the adhesive

Radiation-curable coating systems are gaining ground in an increasing number of applications, thanks to their favorable emission behavior. The most important market segment in Europe is the wood coating sector with over 14%. Matted coatings, varying from very dull to satin gloss, dominate in the wood and furniture coating sector. The matting of 100
