This article presents the results of a study to investigate and identify the technical, educational and economic barriers to using and implementing radiation-curable coatings within the coated and laminated substrate manufacturing industry. This project involved preparing category analyses, identifying and classifying the use and implementation barriers, evaluating and assessing the environmental impacts, and identifying pollution prevention and source reduction research opportunities within the coated and laminated substrate manufacturing industry. In order to accomplish these objectives, information was collected from several sources including literature searches, plant visits, pollution prevention experts, industry representatives, equipment and raw material vendors and trade association personnel. By initiating this project, the EPA has begun a dialogue on pollution prevention with these industries.

Beat the heat / N. Julian K. Danvers in ADHESIVES AGE, Vol. 45, N° 3 (03/2002)  

[article]  inADHESIVES AGE > Vol. 45, N° 3 (03/2002) . - p. s4-s7 Titre : Beat the heat : New challenges for curing material on heat-sensitive substrates Type de document : texte imprimé Auteurs : N. Julian K. Danvers, Auteur Année de publication : 2002 Article en page(s) : p. s4-s7 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement électronique Adhésifs -- Séchage sous rayonnement ultraviolet Coût de production Entretien et réparations Micro-ondes Réticulation (polymérisation) Index. décimale : 668.3 Adhésifs et produits semblables Résumé : While the lamp head in itself is the primary generator for the heat, this article has tried to demonstrate the factors and technology available in this area to deal with this issue. The exact system used depends on the type and scale of application. Microwave technology has particular advantage in powder, fiber optic, hard coat and plastic component applications. A water-filtered lamp here is better suited to webstyle processes. There is a significant overlap between the suitability of UV sources for different applications. Some of the processes involved can be complex. For example, when curing a coating onto pine, heat is a major issue due to sap rising from the wood and damaging the coating. A recent case has seen electrode technology removed in favor of the lower heat and high intensities associated with microwave. With a three-dimensional object, the short length on a microwave system becomes a major advantage when trying to cover the whole surface with an even UV dose. Automotive headlights generally use a three-lamp arrangement to achieve this result. When dealing with large sheets or webs, a water-cooled or filtered system becomes more advantageous due to the continuous span. For example, the printing of a bank note onto either paper or plastic will use this style technology. The choice of lamp head is a complex issue and the factors affecting the design chosen are not straightforward as it is in a trade-off situation. What I have aimed to do is highlight the area that needs to be considered to enable the reader to better judge the situation.

Stratifiés Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Laminating adhesives are used for bonding two substrates together. They can be used in a variety of applications, such as food packaging, aerospace, automobiles, electronics or solar panels. The major technologies include solventborne, waterborne, two-component urethanes and UV-curable resins. UV technology is rapidly gaining acceptance in a variety of industries due to its environmental and economic advantages. During recent years, market demand has been strong for liquid optically clear adhesives (LOCA) for display or touchscreen applications. Key performance requirements include strong bonding strength to the substrates, excellent reliability, high optical clarity and superior moisture resistance. For high-quality displays, low dielectric constant bonding adhesives are also necessary. The moisture barrier performance of UV/EB-cured materials has been discussed in previous publications.2-3 Here, we will examine the durability properties of UV-cured acrylates under three weathering conditions, including Q-Panel laboratory ultraviolet (QUV) testing, 85°C/85% relative humidity and freeze-thaw cycles. The key properties evaluated are optical clarity characterized by percentage of UV-Vis transmission and T-peel strength. In the end, we will discuss the dielectric properties of different types of oligomers.

Converting to electron beam technology / Karl E. Swanson in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 20, N° 6 (06/2013)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 20, N° 6 (06/2013) . - p. 27-29 Titre : Converting to electron beam technology Type de document : texte imprimé Auteurs : Karl E.

All aspects of the converting process are being scrutinized, including the need to make the adhesives and sealants component of converting more environmentally friendly. To this end, the industry is working to use fewer volatile organic compounds (VOCs), thus reducing emissions and odors that can contribute to things like respiratory issues and compromised air quality. Certainly the adhesives and sealants themselves are a worthy target for green innovation. In recent years, adhesive and sealant formulators and manufacturers have made great strides in improving their formulations, not only increasing product quality and durability, but also reducing VOC emissions. A second, perhaps less obvious target for greener adhesive and sealant use in converting lies in the curing processes being used. As the industry is beginning to realize, not all converting processes are created equal. Electron beam (EB) curing technology has grown to become an influential option for forward-thinking converters, especially those that harness web technology. Among its numerous advantages over other curing methods, EB technology produces almost no VOCs, unlike oven-based (thermal) curing.

A cure for PSAs in ADHESIVES AGE, Vol. 46, N° 4 (06-07/2003)  

[article]  inADHESIVES AGE > Vol. 46, N° 4 (06-07/2003) . - p. 22-25 Titre : A cure for PSAs : Radiation curable elastomers help hot-melt producers bolster performance of presure sensitive adhesives Type de document : texte imprimé Année de publication : 2003 Article en page(s) : p. 22-25 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement électronique Adhésifs -- Séchage sous rayonnement ultraviolet Adhésifs sensibles à la pression Adhésifs thermofusibles Adhésion Caoutchouc styrène-butadiène Elastomères Résistance thermique Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Radiation curable elastomers offer new opportunities for hot-melt producers to extend their product grade range towards the high performance pressure sensitive adhesives. Kraton D-KX222C is a radiation curable styrenic block copolymer designed to be highly reactive even in the presence of air. Although it quickly crosslinks when submitted to the UV light, it can be safely processed in hot melt when the appropriate antioxidant package is used. It is known that UV irradiation has to be carefully controlled to ensure the production of optimal and consistent adhesives. However, adhesives based on the radiation curable elastomer offer robust systems less prone to adhesion change upon curing than other competitive materials. The polymer 222 is the polymer of choice for high performing industrial tapes. It can be processed similar to any conventional hot melt without contaminating the hot-melt line and it obeys the same formulation principles as other styrenic block copolymers. It therefore combines the desirable adhesion char-acteristics of rubber-based adhesives such as adhesion on a wide variety of substrates and can be formulated into an extensive range of products with very different properties. Tt is possible to obtain peel adhesion values of 27 N/25mm or a RBT below 5cm, with a SAFT above 160 degrees C. This makes the polymer particularly attractive for the automotive industry, which often requires adhesives with high tack and temperature resistance around 140 degrees C.
