 Vinyl ethers are known as non-irritant reactive diluents for UV-curable formulations. In acrylate based systems they could replace monomeric acrylates providing better diluting properties in combination with higher 1 However, subject of this study will be blends of epoxides together with vinyl ethers. Also in these systems the viscosity of th

The move towards lower VOC emission from paint systems can be achieved by using water-based coatings. In this case film formation requires a low glass transition temperature, Tg, while most applications require a final high Tg and high solvent resistance. Light induced curing is an interesting way to overcome the contradictory demands on 1g. While

Innovative ideas may result from assiduous individual brainwork but mostly emerge from the organized or incidental exchange of thoughts between individuals with expertise in specific fields. Such a synergistic idea generation approach promises highest return in a world where specialization often comes with estrangement even from related subjects. I

In many open molding fiberglass composite processes, volatile diluent monomers are used with oligomeric unsaturated polyester or vinyl ester compositions. Curing with accelerator catalyst allow for large amounts of the volatile monomer to be lost, through surface evaporation, before the surface of the resin compositions can set up. This evaporation

Currently, regarding the coating of exterior automotive parts made of plastics, in Europe the UV technology plays an important role in the field of light systems. The curing of the scratch resistant coating of headlight lenses made of polycarbonate is concerned, as well as the cross linking of the primer coating of reflectors in BMC or thermaiplast

The present paper shows typical applications of photoacoustic spectroscopy to the investigation of photoinitiating systems triplet energy level, quantum yield of intersystem crossing, enthalpy of formation of radicals, bond dissociation energy of amine.

Thermoplastic elastomers can be readily crosslinked at ambient temperature by UV-irradiation inthe presence of a photoinitiator 1.2 These polymers, like styrene-butadiene block copolymers(SBS), have a two-phase morphology, and are commonly used as pressure-sensitive adhesives,in combination with a tackfying resin, and as flexographic printing plate

A new generation of waterborne UV-curable resinè not only shows the same level of product quality compared to conventional UV-curable resins but also can offer in addition some very interesting features for industrial applications. In the present paper performances of UV curable waterborne acrylates are described.
