The application of a range of novel water compatible oligomers in UV vuring processes in described. Two papers are used as reference substrates: a) Wahtman 41 pure cellulose and b) a unique paper/veneer product from waste banaba trees.

Free radical polymerization is largely encountered in the Radiation Curing area (e.g. [1]). the photoinitiation step efficiency is largely gocerned by the quantum yield of the produces initiating radical R' that photoinitiator PI, and the chemical reactivity of these radicals.

UV technology has been used in wood coatings since the late seventies. Until now all of theseapplications have been based on 100% UV curable products, formulated mainly for roller coaterapplication, so it was only possible to coat flat panels. After many developments, UV technology now offers a broad range of 100% UV curable resins and reactive dil

Sustainability is the new Green….and will continue to gain influence in the global marketplace. A major movement is underway, which include efforts by environmentalists, government agencies, manufacturers, consumers and others, to improve Sustainability worldwide. The Coatings marketplace, consisting of raw material manufacturers, equipment supplie

Water-based, radiation curable dispersions are well known in the UV/EB industry for decades. Particularly in the last few years this product group has experienced substantial growth outpacing that of traditional radiation curable raw materials. Target markets are those, where their beneficial properties such as absence of sensitizing monomers, no n

Polycarboate diol (PCD, Asahi Kasei) and dimethylol propanoic acid (DMPA, Across) were dried and degassed at 80◦C under vacuum for 6h. Extra pure grade of polydimethylsiloxanes (PDMS, Mn=550, Sigma Aldrich) was used as received. Isophorone diisocyanate (IPDI, Bayer Material Science) and triethylamine (TEA, Samchun Pure Chemical) were dried over 4 A

The use of UV and EB curing inks is growing in the European Graphic Arts market. Not only do they give excellent print quality but they are also solvent free, a huge benefit in this environmentally driven world. One particular application where UV and EB curing inks continue to develop is in the prestigious food packaging market. In order to sustai

During resent years the improvement of scratch resistance of UV is an actual topic. High quality parquet coatings but also automative topcoats should be scratch resistant even under heavy strains.
