Achieving adhesion to difficult substrates / Mike J. Idacavage in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 21, N° 9 (09/2014)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 21, N° 9 (09/2014) Titre : Achieving adhesion to difficult substrates : A new material can be used to improve adhesion in a variety of substrates Type de document : texte imprimé Auteurs : Mike J. Idacavage, Auteur Année de publication : 2014 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Adhésifs à usages médicaux Adhésion Dents -- Soins et hygiène Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Adhesion, or lack of it, is one of the most critical attributes for most adhesives, coatings and inks. A variety of options can be explored when it comes to adhesion. Two of the most common types of adhesion are mechanical and chemical. Mechanical adhesion occurs when adhesive materials physically lock into the crevices of the surface. This requires that the substrate surface be physically abraded or chemically etched, unless the substrate has a naturally rough surface. Chemical adhesion can be improved through the use of coupling agents, such as silane acrylates, or through under curing a primer coating. When improved adhesion was recently required in several different UV-curable applications, a specific material was developed that could be used for a variety of applications.

Advancements in UV LED curing technology for adhesives / Pamela Lee in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 21, N° 6 (06/2014)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 21, N° 6 (06/2014) Titre : Advancements in UV LED curing technology for adhesives : The gaps that previously existed between traditional lamp solutions and UV LED-based curing systems have been narrowed Type de document : texte imprimé Auteurs : Pamela Lee, Auteur Année de publication : 2014 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Adhésifs à usages médicaux Adhésifs dans les automobiles Diodes électroluminescentes Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Assembly and manufacturing processes are highly dependent on the rapid and effective curing of ultraviolet (UV) adhesives. Historically, mercury arc lamps have been used as the curing source in a wide range of industrial applications and processes to polymerize adhesives. With its broad spectrum and high output at various peak wavelengths in the UVA, UVB, and UVC regions, lamps have provided an effective solution for many years. However, older mercury lamp solutions incur disadvantages such as shorter life spans and higher operational costs, which can be eliminated by a newer technology: light emitting diode (LED) solutions. Until recent years, UV LEDs have been a technology faced with a number of barriers that have prevented wide commercial adoption. High cost and limited availability of LEDs, low output and efficiency, and thermal management challenges, combined with adhesive compatibility, were factors that prohibited market traction. With advancements in UV LED technology, however, the use of UV LEDs for adhesive curing has become increasingly prominent.

An eye for detail / Gernot Tögel in ADHESIVE TECHNOLOGY, Vol. 19, N° 1 (03/2002)

[article]  inADHESIVE TECHNOLOGY > Vol. 19, N° 1 (03/2002) . - p. 19-21 Titre : An eye for detail : UV-reactive adhesives are providing the user with a variety of benefits. The authr takes a look at how these binders can reduce costs and environmental damage Type de document : texte imprimé Auteurs : Gernot Tögel, Auteur Année de publication : 2002 Article en page(s) : p. 19-21 Langues : Anglais (eng) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Photoréticulation Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The role of UV-reactive adhesives is becoming more and more important in numerous industrial production processes, such as printed circuit boards, mobile phones and the optical industry. WXith the appropriate UV equipment the advantages to the user are significant. The user can specify the exact moment of curing and as a result achieve miminum curing times. Another benefit is that the adhesives are solvent-free, which ensures a high degree of environmental protection as well as increased safety in the work place. UV reactive adhesives and casting compounds are one-component and cold-curing reaction systems where the curing mechanism is initiated by UV irradiation. They do not contain solvent and are mainly composed of plastic combined with a photoinitiator. The type of plastic materials employed depends on the application. Acrylates, epoxy resins, silicones or polyester resins are commonly in use. A UV reactive adhesive that cross-links by means of free radicals is composed of plastic monomers, oligomers, photoinitiators and other additives. In this state, the adhesive can be easily applied. The ultraviolet irradiation splits the photoinitiator into free radicals that initiate the generation of polymer chains. In the cured state, the UV adhesive is composed of cross-linked polymer chains. As the entire adhesive volume has to be irradiated by UV in order to cure completely, at least on the parts that have to bonded, those parts must consist of UV transparent materials.

Danvers, Auteur Année de publication : 2001 Article en page(s) : p. 32-37 et p. 48 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Adhésifs thermofusibles Electrodes Micro-ondes Réflectivité thermique Systèmes de refroidissement Index. décimale : 668.3 Adhésifs et produits semblables Résumé : With the advances being made in material science and technology, there is an increase in the amount of polymeric materials used within today's manufacturing environment. The growth of UV curing for its process, performance and environmental factors is presenting new challenges on how to best cure material on thermally sensitive substrates. This article will look at the technology and processes that can be used when the inherent heat generated as part of the UV-source is detrimental to the substrate. It will investigate different types of UV curing systems that can be used for paying special attention to the heat transmission properties associated with them as well as looking at some sample applications in which they can be used. For the benefit of this article, discussions will be based around electrode (arc) and microwave UV equipment. While EB (electron beam) and pulsed UV are both alternative radiation-curing technologies, these will be not covered.
