“…The artificial aging method affects the adhesion of the tested adhesives, depending on the type of silicone resin and the amount of cross-linking agent. According to the literature, artificial aging reduces adhesives stiffness [26]. The reason for the decrease in adhesion may be the absorption of light with a wavelength below 400 nm, which may result in the bond breaking and oxidation of the side hydrocarbon groups [27].…”

The paper presents the results of research on the UV radiation influence on the self-adhesive properties of silicone adhesives. The adhesives were obtained by cross-linking commercial resins (PSA 590, Q2-7566) at the temperature of 110°C, using different amounts (0–3 wt%) of bis(2,4-dichlorobenzoyl) peroxide. Self-adhesive properties of adhesives such as adhesion, tack, and durability before and after aging were determined. The adhesives showed stable self-adhesive properties, however, the PSA 590 adhesive had a higher maximum operating temperature than the Q2-7566 adhesive.

“…The methyl groups attached to the Si atoms are sterically undisturbed and can rotate freely; thus, the main polar chain -Si-O-Si- is shielded and in consequence, the intra- and intermolecular interactions are minimized. Therefore, to improve its mechanical properties, high-density cross-linking is necessary [ 19 , 20 , 21 , 22 ] Driven by the need for regulatory compliance and changing performance requirements, silicone PSAs, based on new silicone chemicals and curing mechanisms, have emerged [ 18 , 23 , 24 ].…”

Influence of Acid-Modified Clinoptilolite on the Self-Adhesive Properties of Silicone Pressure-Sensitive Adhesives

The preparation of a new “eternally alive adhesive” based on silicone pressure-sensitive adhesives with clinoptilolite is presented. Neat and acid-modified (i.e., treated with sulfuric acid (VI)) clinoptilolite was used. The effect of clinoptilolite acid treatment on the adhesive properties of pressure-sensitive adhesive tapes was tested. The obtained tapes exhibited increased thermal resistance when compared to the reference tapes. Despite introducing the filler, the pressure-sensitive adhesive tapes maintained good functional properties. The new self-adhesive materials show promising implementation potential where increased thermal resistance is required.

“…Ein unterschiedliches Verformungsverhalten ist nicht erkennbar. Alle Tests zeigen zudem eine weitgehend lineare Zunahme aller Messwerte, was, aufgrund des nichtlinearen Verhaltens des Silikons in den Haftversuchen[11], nicht zwingend zu erwarten war.Unter der maßgebenden Einwirkungskombination im Grenzzustand der Gebrauchstauglichkeit (GZG) verformt sich die Balkonspitze um 4,14 mm (f1,ges) und die Klebung um 1,96 mm (f1,Kleb). Diese Werte steigern sich im Grenzzustand der Tragfähigkeit (GZT) auf 5,64 mm (f1,ges) und 2,63 mm (f1,Kleb).…”

Lastabtragende Klebungen sind in der Lage, Dauer-, Kurzzeit-und Stoßbelastungen zu übertragen. Sie ermöglichen neue und innovative Konstruktionen. Aufgrund des Alterungsverhaltens der geklebten Verbindung sind jedoch Umwelteinflüsse bei der Bemessung zu berücksichtigen. Dieser Beitrag zeigt die Entwicklung eines neuartigen Aussteifungselements aus Glas mit Absturzsicherung, bei dem Klebungen einen maßgeblichen Beitrag zum Abtrag der unterschiedlich lang einwirkenden Lasten leisten. Teil der Entwicklung ist ein experimentelles Testprogramm sowie eine numerische Simulation mit Volumenelementen und Feder. Das Ergebnis ist ein einsatzbereites geklebtes Aussteifungselement und dessen Bemessungskonzept. Load-bearing bonding for in-plane loaded glass balustrades. Load-bearing adhesives are capable of transmitting permanent, short-term and impact loads. They enable new and innovative designs. However, due to the aging behaviour of the bonded joint, environmental influences have to be taken into account in the design. This article shows the development of a new type of stiffening balustrade which is in-plane loaded and made of glass. Bonding makes a significant contribution to the transfer of loads acting over different periods of time. Part of the development is an experimental test program as well as a numerical simulation with solid elements and springs. The result is a ready-to-use bonded stiffening element and its design concept.
