Correlating substrate surface analysis to adhesive performance / Michaeleen Pacholski in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 22, N° 11 (11/2015)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 22, N° 11 (11/2015) . - p. 15-22 Titre : Correlating substrate surface analysis to adhesive performance Type de document : texte imprimé Auteurs : Michaeleen Pacholski, Auteur Année de publication : 2015 Article en page(s) : p. 15-22 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique. L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1. C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

In some cases, such as steel and HDPE panels, the surface chemistry of the substrate is the dominant influence to adhesive performance. In the case of corrugated cardboard, the surface roughness and fiber integrity were critical to adhesion. Comprehensive analysis of the surface chemistry and roughness of the substrate can lead to ideal PSA selection, as well as aid in troubleshooting for any system showing less-than-ideal adhesion. The data presented in this study also illustrate the importance of considering both the adhesion data and the analytical data simultaneously to determine the factors most important for a given adhesive/substrate system. For example, the surface roughness of the bottles varies, but does not vary systematically with the peel data. But, the surface chemistry of the flame treated bottle (high O and surface polarity) indicates why peel is high. Similarly, both the surface chemistry of the substrate and surface roughness can be investigated to guide troubleshooting where the adhesion is not at the desired level. Lastly, there are specific substrate and adhesive combinations that end users define as key for qualifying adhesives. This study demonstrates that the selection of substrate surfaces has a major impact in determining if a given adhesive meets performance targets.

Clean and green / Janet Page in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 22, N° 11 (11/2015)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 22, N° 11 (11/2015) . - p. 25-27 Titre : Clean and green : Pressure-sensitive adhesives offer the benefit of having low to no VOCs Type de document : texte imprimé Auteurs : Janet Page, Auteur Année de publication : 2015 Article en page(s) : p. 25-27 Langues : Américain (ame) Catégories : Adhésifs -- Emballages Adhésifs dans les automobiles Adhésifs sensibles à la pression Composés organiques volatils Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Fears and concerns about volatile organic compounds (VOCs) have become more prominent in recent years—although they have been around for decades. For example, many types of pressed wood contain formaldehyde, a known carcinogen that releases chemical fumes into the air for many years. In addition, in the 1970s, it was common for homeowners to install urea-formaldehyde foam insulation (UFFI) to save energy. A substantial number of these homes had high levels of formaldehyde in the indoor air soon after installation, according to the U.S. Consumer Product Safety Commission. Statistics show that “off-gassed” VOCs can result in a plethora of both short- and long-term adverse health effects, while also posing a number of environmental concerns—from indoor air quality to ground-level ozone formation. According to the Minnesota Department of Health, the toxicity and health risk of VOCs depends on each specific chemical, how much out-gassed chemical is in the air, and how long and how often a person breathes it in. Obviously, VOCs should be avoided. Today, many converters and manufacturers pay close attention to the materials used in their end products in order to help ensure that the products are safer and healthier for consumers; these include pressure-sensitive adhesives (PSAs).

Improving the quality and efficiency of adhesives in the glass industry / Dave Bordwell in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 22, N° 11 (11/2015)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 22, N° 11 (11/2015) . - p. 31-32 Titre : Improving the quality and efficiency of adhesives in the glass industry : New proportioner technology addresses adhesive dispense accuracy and other issues in construction applications Type de document : texte imprimé Auteurs : Dave Bordwell, Auteur Année de publication : 2015 Article en page(s) : p. 31-32 Langues : Américain (ame) Catégories : Adhésifs -- Appareils et matériel Assemblages collés Construction -- Matériaux Joints d'étanchéité Mélanges (chimie) Verre -- Collage Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The production of both insulating glass and curtain walls incorporates bonding and sealing steps that use multi-component adhesives. The success of these bonding and sealing steps depends on proper mixing and accurate, on-ratio dispensing of the adhesive components. Many of the mixing and dispensing methods used today have serious drawbacks that can impact final product quality, material costs, and production time. Recent additions to the proportioner market incorporate new technology that addresses many of these issues. This new technology offers improved real-time ratio assurance, reduced material usage and enhanced tracking of key information. With these benefits, final product quality is improved and both material cost and production time are decreased.
