The fundamental physical challenge of low temperature curing powder coating systems like UVpowder is based on the inconsistency between the storage stability and the melt viscosity of the powder. In particular if crystalline compounds are used to improve flow, the glass transition temperature and thus the storage stability is decreased significantl

Hyperbranched polymers (HBP) belong to a group of molecules called dendritic polymers, which have peculiar and often unique properties. They are characterized by a highly branched backbone, which give access to a large number of reactive groups. Their branching pattern,  characterized by a low amount of intermolecular or intramolecular entangl

Currently, the field of photopolymerization is dominated by (meth)acrytate systems. Thiol-ene photopolymerizations constitute a class of polymerizations, which have many of the advantages of acrylate polymerizations including spatial and temporal control of polymerization, solventless polymerization, and good material . Further, these reactions hav

UV-curable coatings are mainly discussed for the application on 2-dimensional substrates. If 3- dimensional substrates are painted with pure acrylate based UV-coatings using conventional lamp equipment for exposure, lack of curing in shadow areas will occur. Until now Dual Cure Systems, involving a UV-curing and a thermal curing step, are proposed

The consumer's point of view... The only thing the consumer can rely on is the information given by the manufacturer (or the salesman). But unless that information is comparable to something, it will be of little real value. So how can we give the consumer reliable and comparable information? Norms and labels should give the consumer the necessary

EB/UV Curable technology has been known for many benefits including zero-VOC, production speed enhancement, overall cost reduction, and its processing enabling capability. With recent advances in FDA testing protocol, raw material development, and low cost EB curing units, EB coatings have emerged as one of the mainstream chemistries for food packa

The use of light to cure systems for applications ranging from protective coatings on floor tiles and optical fibers to coatings on compact discs has grown steadily since the first commercial uses were reported over fifty years 1 Virtually all free-radical photocurable systems today are based upon the following components: functionalized oligomers,
