around the rate of adoption and usefulness for the wide
range of UV curing applications. Essentially, the question has been "will UV LED curing technology fulfil its promise?" Well, the answer is "yes"! In fact, it has exceeded the promise and will continue its strong growth and accelerate and open new UV curing markets.
The early concerns of output, lifetime and cost have ail been met with rapid technology and product improvement. Today, UV LED curing technology meets a wide range of application requirements and is continuing to improve at a rapid pace. Lamps of 16W/cm2, which cure at the highest of speed requirements, have been shipping in volume for more than two years. Lamp manufacturers routinely quote lifetime expectations in excess of 20,000hr of 'on-time' - double what was quoted a few years ago. Soon, leading manufacturers will be producing lamps promising an even higher number of useful 'on-time' hours - likely around 30,000 hr matching or exceeding the life of various curing installations.
Nearly ail UV curable materials providers have UV LED curable chemistries along with aggressive technology and product roadmaps. While the monochromatic nature of UV LED lamps requires special consideration from the chemists it has not been a long-term impediment as once thought.
One of the most exciting aspects of utilising a UV LED curing process is that it opens many new process possibilities with its precise electronic control of energy delivery. Many users have tailored their processes to achieve results unattainable though other means. Today there are many proprietary uses of energy control across varying applications.En ligne : https://drive.google.com/file/d/1EJdqQgrZvZqPS9pLHRgeGRjO4ZmL1ZM1/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=21150

Réticulation (polymérisation)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Spot curing lamps have been around for about 15 years. The first systems were built by adhesive manufacturers who needed small portable curing systems to process and evaluate their adhesives and coatings. They started out as what would kindly be considered prototyping or demonstration tools that were barely able to cure the adhesives in a reasonable time. At best, the intensity was about 300 mW/[cm.sup.2] from the end of the light guide, and the power quickly dropped off to a fraction of the initial intensity. This meant that if an engineer specified a process with the lamp when new, the process very quickly fell below the minimum requirement, and the potential for producing bonds that were incomplete was very high.
At this point, the adhesive manufacturer was not as concerned with perceived process variables that lay with the equipment, but rather with the adhesive variables, as this was where the engineer had the least amount of experience and therefore the greatest amount of anxiety as to how the process was to be verified. To be fair, there were times when the adhesive was the culprit due to improper formulation or lack of care taken in how the adhesives were stored in the customer's facility, but usually the problem lay with the poor performance of the existing spot cure equipment.
The difficulty was diagnosing and correcting this equipment problem while still maintaining a working process. One method presented itself when equipment manufacturers began to offer radiometers to determine what intensities were being generated by the low power lamps and to allow the engineer the ability to make a time adjustment to compensate for the unpredictable loss in generated intensity.En ligne : https://drive.google.com/file/d/1se6UOihhXqhGIaYLuuIfXdUFDNQGBXQm/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=20387

Réticulation (polymérisation)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Understanding the differences between thin and thick layer resin markets, applications,processing requirements, and chemistry is helpful in deciding whether or not photocuring can or should be used as a successful alternative to some other coating or bonding method.
Furthermore, once the distinction is clear, and the range of properties clearly understood,choosing the best resin and equipment for the application becomes a much easier task.Note de contenu : - Thin layer resins - UV inks and coatings

RhéologieIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Analyzing the development of new novel high performance emulsion pressure sensitive adhesives. We have developed a family of high performance acrylic pressure sensitive adhesives (PSAs) using a novel emulsion polymerization technology. These new PSAs exhibit an excellent balance of peel and shear performances. The base polymers of these PSAs are compatible with many traditional tackifiers and other additives that allow greater formulation versatility for paper and film applications. This paper presents the new base polymers properties, capabilities and highlights our recent work for the removable and repositionable PSA applications. The markets and technology in the PSA industry are growing rapidly. Due to the VOC concern, many of the new applications also utilize emulsion PSAs. To meet the challenging market needs, we utilized new raw materials, processes and new chemistry to develop new emulsion PSAs that have higher performance and better environmental compliance. Although generally, waterborne PSAs have some shortfalls in performance compared to solution PSAs, new technology is closing this gap. The versatility of acrylic chemistry and polymerization processes allowed us to design base polymers with unique properties. Note de contenu : I. New GELVA emulsion polymers
