Photoinduced free radical Polymerasation of unsaterated polyesters in presence of multicrylate reacting diluents

The polymerisation of coatings and printing inks using ultraviolet light (UV) or electron beam energy sources (EB) is constantly challenged to improve performances, to increase durability, to reduce costs and to satisfy environmental and safety regulations. In particular, UV curing had success in several applications as clear top coating, for the p

UV Flexo Printing under Atmospheric and Oxygen-reduces Conditions

UV flexo printing in the narrow web field has taken hold for many years, especially in label printing.In wide web flexo printing UV is increasingly used on in-line presses, e. g. for liquid packaging and for the printing of aluminium foil. There are also UV installations on CI flexo presses whether for cardboard or for foils. Another application on

Synthesis and Radical Polymerization of Hydrolytically Stable Cross-linking Monomers for Dental Adhesives

Dentin adhesives are used in restorative dentistry to achieve a strong bond 'between the filling composite and dental hard tissues (dentin and enamel). Besides the photoinitiator and solvent, such as water, ethanol and acetone or mixtures thereof, the currently used self-etching dentin adhesives contain different monomer components. The main compon

Microproperties of Colloidal Silica/ Acrylic UV-curable Nanocompoditie Clearcoats Comperative Methods to Evaluate Scratch Abrasion

Organic coatings are well known to be sensitive to scratch, abrasion and chemicals. In these last few years, research was focused on the preparation of nanocomposite coatings which bring partial answers to these issues. One way to prepare nanocomposites is to use concentrated silica organosols where the continuous organic phase can be either monome

Photo-induced Cross-linking Copolymerization Occurring With and Without Phase Separation

The photocurable compositions are based on the mixtures of components of various physicalproperties and chemical structures. The structure of the network formed during the curing isdetermined by the reactivity of the monomeric units and by the mutual solubility of the monomers and oligomers used. Bis-GMA 4-(2-hydroxymethacryloxypropoxy)phenyl]prOpa

Weather Resistant Radiation Curable Monomers and Oligomers for Exterior Applications

The weather resistance of an exterior coating is one of the main properties required by theend-user. The backbone structure of several monomers and oligomers has been investigated andsubjected to accelerated weathering tests. This ongoing study has shown that most of these acrylates, which are free from light stabilizers, can stand more than 5000 h

An Effective Wood Protective and Water Repellency Thin Layer by Photgrafting

Photoinitiated graft polymerisation remains of the most efficient methods to modify rapidly the surface properties of organic substrates. This technology has been successfully applied to various organic materials, in particular on the wood, to improve the weathering and chemical resistance. The photografted thin-layer proved to be very efficient pr

Advances in Cationic UV-Curing Pigmented System for Flexible and Rigid Packiging Apoplications

Cationic UV-curing systems based on cycloaliphatic-epoxides continue to progress across a widespectrum of end applications, Including metal decoration, flexographic printing, rapid prototyping and electronic applications. The present study has been aimed at identifying ways of achieving rapid and efficient photo-induced cationic polymerization of h
