Der Einsatz von lastabtragenden Klebverbindungen zählt zu den Fügetechniken des Konstruktiven Glasbaus. Dabei sind transparente und hochfeste Klebstoffe als Alternativen zu den derzeit verwendeten Silikon-Klebstoffen von besonderem Interesse. Der vorliegende Beitrag enthält eine Ergebnisauswahl verschiedener Untersuchungen an Klebeverbindungen mit transparenten Acrylaten, Epoxidharzen und Polyurethanen. Die experimentelle Studie umfasst Analysen zu den thermomechanischen Eigenschaften der Klebstoffe sowie zu den Zugfestigkeiten und den lichttechnischen Eigenschaften der geklebten Verbindungen. Transparent Adhesives for Glass-and-Metal Joints. The use of load-bearing joints is one of the relevant joining techniques in glass construction. Here, transparent and high-strength adhesives are alternatives to the currently used silicone adhesives. Therefore, they are of particular interest. This article contains a selection of various results from studies of adhesive joints using transparent acrylics, epoxy resins and polyurethanes. The experimental study includes analyses of the thermo mechanical behavior of the adhesives as well as investigations of the tensile strength and the optical properties of bonded joints.

“…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

et al. 2023

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.

“…The methyl groups attach the Si atoms, and they are steric undisturbed and can rotate freely, and as a result, the main polar chain -Si-O-Si-is shielded and allows only a few intra-and intermolecular interactions. That is why polysiloxane chains require chemical cross-linking with high cross-link density in order to obtain the best mechanical properties [9].…”

Research was carried out on the influence of various silicone compounds on the properties of pressure-sensitive adhesives. Silicone-based pressure-sensitive adhesives have good self-adhesive properties and are used in many different industries. However, their thermal resistance is relatively low. In order to improve this property, modifications were made to these adhesives. Compositions were tested, such as viscosity or thermogravimetric analysis, as well as tests of finished products in the form of self-adhesive tapes, i.e., peel adhesion, tack, cohesion at room and elevated temperature, SAFT test (Shear Adhesive Failure Temperature), pot-live (viscosity) and shrinkage. During the tests, an increase in thermal resistance (225 °C), lower shrinkage (0.08%), and lower viscosity was achieved (16.5 Pas), which is a positive phenomenon in the technology of pressure-sensitive adhesives. Thanks to this research, the properties of silicone self-adhesive adhesives have been significantly improved.
