Abstract Silicone pressure-sensitive adhesives are characterized by very good self-adhesive and functional properties. The first group includes: tack, adhesion and cohesion. No less important are the functional properties: maximum working temperature, shrinkage, resistance to external factors and yellowing. It is well known that silicone adhesives are materials for special applications due to their properties, namely surface tension, high UV transparency, good thermal stability, low intermolecular interactions or low surface tension. This paper attempts to investigate the influence of environmental conditions and PSA aging time on the most important functional and self-adhesive properties. This is an important aspect in terms of the use of this type of materials and their suitability for use. The tests were carried out after 1 h days and after a 6 month. To investigate the impact of environmental conditions samples (tapes and joints tapes with a steel substrate), they were conditioned in a climatic chamber simulating environmental conditions by 20 days.

Introduction Adhesives are one of the most important methods for combining different elements. Our ancestors, centuries ago, also used this connection method using, for example, natural rubber. In this way, they were able to bond different materials, both wood, stone and feathers. It also suited them to produce simple tools, such as arrows. The first self-adhesive tape, obtained by Egyptian scholars more than 6000 years BC, was based on starch paste, which was applied to fabric strips. They were also able to make the first surgical bandages from the mixture of honey and fat [1, 2]. Over the centuries, the technology of obtaining adhesives did not develop significantly. Natural sticky substances were still used. The real evolution of pressure-sensitive adhesives has been developed through the use of polymers. Already in 1932, the first patent for adhesives based on acrylates was granted [3]. Pressure-sensitive adhesives are sticky substances that, when separated from the solvent, adhere to the surface in a dry state. They should be characterized by hig
