Rayonnement ultraviolet
Réticulation (polymérisation)Index. décimale : 667.9 Revêtements et enduits Résumé : The author explain how a new technology is set to change the face of UV curing by making it cheaper, simpler and more effective.
Since the 1970s, ultraviolet (UV) curing has been an integral part of many manufacturing and printing processes. UV materials are literally liquid polymers that are cross linked by a reaction that is iniated by UV light. The resulting polymer is durable and can act as an adhesive, coating, varnish, paint or ink. Many modern processes rely heavily on UV cured materials. Without UV curing there simply would be no such thing as optical fibres. They are all coated using UV curing techniques to provide flexibility and for cable identification. Neither would there be compact discs because the protective coating over the sputtered surface is only practical in high speed production with the 'instant cure' that UV can provide. In addition, mobile phones and disc drives would cost far more without UV as the instant cure means that products can be passed through expensive jigs quickly and economically. The durability of UV coatings suits highwear items. For example, lipstick tubes are UV coated because acid from fingers is prone to wear off the ink and brake linings can be ink jet printed with UV inks that ensure the printing stays put in hot, wet and hazardous conditions. In the publication industry we can all remember the laminated shiny covers on books and magazines that looked expensive on the self but extremely tatty when they started to peel off. Water and solvent based coatings matt as the carrier liquid dries off but UV coating simply solidifies and stays shiny. This makes the technique ideal for glossy magazines and other packaging applications example of which can be found in every bookshop and supermarket in the country.Note de contenu : - Limitations of existing technology

The electrochemical and spectral properties of these compounds were investigated. The synthesised dyes were found to be capable photosensitisers for radical (reducible/oxidisable) and cationic polymerisations, respectively. In radical polymerization, better results in the oxidisable process were achieved.

In this study, polyol was studied as a diluent for formulations containing cycloaliphatic epoxide and oxetane in order to evaluate the effect on coatings properties and curing kinetics. The addition of polyol was shown to have an effect on both mobility of the cation as a chain transfer agent, along with the more general effect of flexibility, as evidenced by the hardness data, which increased when a small amount of polyol was added, but decreased as more polyol was included in the formulation. In terms of crosslinking kinetics, it was found that the inclusion of polyol resulted in an increase in conversion during UV irradiation. The level of polyol also had an effect on other properties, such as Tg and crosslink density.

The amount of isophorone diisocyanate was varied during the synthesis. The effects of NCO:OH ratio and HEMA on the structural and physicochemical properties of UV-cured IPEUMAs were investigated. As the NCO:OH ratio increased, the tensile strength and thermal stability increased, whereas the elongation and hydrolytic degradation of the film decreased. The higher strength and thermal stability for higher NCO:OH ratio may be due to the increase in intermolecular hydrogen bonding in the UV-cured film. UV-cured IPEUMA films also show excellent chemical and solvent resistance.
