The latest developments in polyurethane structural adhesives / Fabien Choffat in ADHESION - ADHESIVES + SEALANTS, Vol. 21, N° 3/2024 (2024)  

[article]  inADHESION - ADHESIVES + SEALANTS > Vol. 21, N° 3/2024 (2024) . - p. 26-28 Titre : The latest developments in polyurethane structural adhesives Type de document : texte imprimé Auteurs : Fabien Choffat, Auteur ; Antonio Corsaro, Auteur ; Steffen Kelch, Auteur ; Marco Poltera, Auteur Année de publication : 2024 Article en page(s) : p. 26-28 Langues : Multilingue (mul) Catégories : Adhésifs structuraux Colles bi-composante:Adhésifs bi-composant Polyuréthanes Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Structural adhesives play a key rote in creating strong and reliable bonds between a wide range of substrates in a variety of industries ranging from manufacturing to construction. These adhesives are based on polyurethane (PUR) and, because of their exceptional properties, can be used for many different purposes. Note de contenu : - The application determines the choice of raw materials - Product innovation - Rail casting materials : improved processing - Optimum product properties - Fig. 1 : The range of typical types of PUR adhesives and their mechanical properties. - Fig. 2 : Curing behavior of conventional and chemically modified "curing-by-design" rail fixing materials - Fig. 3 : Mechanical (top) and manual application (bottom) of rail casting material on a transport infrastructure construction site - Fig. 4 : Open time or processing time and curing time after the application of conventional and chemically modified "curing-by-design" rail fixing materials En ligne : https://drive.google.com/file/d/1oXxhRhzyhxet0_K-KF0a7xg0bH1j3PCB/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=41396 [article]
