The good news is that adhesive and sealant formulators have more choices than ever to help them achieve their goals. The bad news—ironically—is that formulators have more choices than ever to help them achieve their goals.

Performance and sustainability in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 27, N° 5 (05/2020)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 27, N° 5 (05/2020) . - p. 18-23 Titre : Performance and sustainability : Soy-based adhesives and sealants excel in wide-ranging applications Type de document : texte imprimé Année de publication : 2020 Article en page(s) : p. 18-23 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Biomatériaux Chaine logistique Colles:Adhésifs Construction -- Matériaux Mastics Ressources renouvelables Soja et constituants Index. décimale : 668.3 Adhésifs et produits semblables Résumé : U.S. soy delivers on sustainability and performance for myriad industries and products—including adhesives and sealants. Renewable by nature, soybean oil is used in a diverse array of bio-based products. From biofuels for vehicles and resins for car and farm machinery parts to spray foam insulation and lubricants, versatile U.S. soy delivers on sustainability and performance for myriad industries and products. Thanks to the environmental benefits and enhanced consumer perception of renewable products, soy has become a popular choice for many manufacturers. The farmer-led United Soybean Board (USB) is committed to bringing useful information to companies to fulfill sustainability goals and improve products with soy. According to John Jansen, USB’s vice president of Oil Strategy, investing in soy-based technology and innovation is an easy decision. "Soy is a product that is sustainable and in abundant supply," Jansen said. “We can identify markets where soy can help these companies become more sustainable while creating a higher demand for U.S. soy, and that’s a win for everyone".

Moisture-permeable polyurethanepressure-sensitive adhesive addresses needs of wearable devices / Makito Nakamura in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 27, N° 5 (05/2020)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 27, N° 5 (05/2020) . - p. 24-27 Titre : Moisture-permeable polyurethanepressure-sensitive adhesive addresses needs of wearable devices Type de document : texte imprimé Auteurs : Makito Nakamura, Auteur ; Haru Kawasaki, Auteur ; Hitoshi Shimona, Auteur ; Chitoshi Suzuki, Auteur Année de publication : 2020 Article en page(s) : p. 24-27 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésifs à usages médicaux Adhésifs dans les équipements électriques/électroniques Adhésifs sensibles à la pression Adhésion Dents -- Soins et hygiène Humidité Médecine -- Appareils et matériel Perméabilité Polyacryliques Polymères en médecine Polyuréthanes Prothèses dentaires Silicones Les silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki). Index. décimale : 668.3 Adhésifs et produits semblables Résumé : It is difficult to simultaneously achieve both moderate adhesion to the skin and strong adhesion to a wearable device, but a new polyurethane pressure-sensitive adhesive is providing a solution. Wearable devices are used in medicine to continuously monitor signals such as electrocardiograms and electroencephalograms. They can also be used to monitor physical conditions during exercise. To improve the accuracy of the analysis, many studies have been conducted by directly attaching wearable devices to the skin using a pressure-sensitive adhesive (PSA) sheet. When a PSA sheet is continuously applied for an extended time, however, the user's skin becomes macerated due to the moisture generated from their skin. This increases the amount of peeled stratum corneum (outer layer of the skin). PSAs used in this application must meet several requirements, including: patient/user safety, appropriate adhesiveness to the skin, reduction of the humidity that results from sweat after application, and strong adhesion to the wearable device. In response to all of these demands, studies have been conducted using a silicone PSA and an acrylic PSA for wearable devices. The acrylic PSA was found to have insufficient moisture permeability, and there are problems with sweating that may occur if it is applied for a long time. On the other hand, the silicone PSA can reduce the humidity from sweat due to its moisture permeability caused by its high free volume. It is difficult to simultaneously achieve both moderate adhesion to the skin and strong adhesion to the wearable device.

UV curing in green manufacturing / Craig Fillers in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 27, N° 5 (05/2020)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 27, N° 5 (05/2020) . - p. 28-31 Titre : UV curing in green manufacturing Type de document : texte imprimé Auteurs : Craig Fillers, Auteur ; Laurel Yaste, Auteur Année de publication : 2020 Article en page(s) : p. 28-31 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Diodes électroluminescentes Index. décimale : 668.3 Adhésifs et produits semblables Résumé : UV LED curing offers multiple environmental and productivity benefits compared to traditional mercury bulbs. One of the most popular solutions for utilizing adhesives, coatings, polymers, and resins in green manufacturing without resorting to solutions that require time or heat to cure/dry involves using ultraviolet (UV) radiation and a material that is capable of utilizing its energy to provide for a fast, on-demand cure. While mercury-based bulbs have long been a staple of the UV curing process, UV light-emitting diodes (LEDs) have made vast strides in becoming an excellent alternative due to their lower operating costs and superior lifetime over conventional bulbs.
