Abstract
The purpose of this work was to obtain single-sided tapes with different concentrations of kaolin and to check its impact on the self-adhesive properties of commercial adhesives. The most important self-adhesive properties were examined, such as tack, peel adhesion, shear strength, shrinkage, and thermal resistance. Tapes based on silicone PSAs with kaolin can be used in many branches of industry to bond elements operating at elevated temperatures, i.e., in aeronautics, aerospace including solar cells for satellites and space stations. There are few reports on one-sided adhesive tapes based on silicones with the addition of kaolin. However, taking into account the number of their potential applications, we did self-adhesive tests and explained how kaolin affects them. In addition, the reactivity of the crosslinking compound and silicone adhesive during the crosslinking process and the thermal effects of this process were also examined. In connection with the various applications of the obtained tapes, also the flammability and heat of combustion were tested, in accordance with applicable standards. As a result of the tests, one-sided self-adhesive tapes with new properties (increased temperature resistance, less shrinkage, and increased resistance to flammability) were obtained.
Highlights
Pressure-sensitive adhesives (PSA) are adhesives with the ability to form the joint between bonded surfaces under low pressure
According to the guidelines suggested by the tape manufacturers, they meet the requirements for single-sided adhesive tapes in terms of selfadhesive properties
The values of shear strength do not change during the modification with kaolin
Summary
Pressure-sensitive adhesives (PSA) are adhesives with the ability to form the joint between bonded surfaces under low pressure. One of their advantages is the ability to detach the adhesive from the surface without leaving any traces [1]. PSAs are adhesives that form bonds under low pressure, In the 1960s, silicone adhesives were introduced to the market. Since 2000, there has been an increase in interest in silicone PSAs, especially in applications such as medical and industrial tapes. The foregoing examples describe the growing range of potential commercial uses where silicone pressure-sensitive adhesives are being introduced [5,6,7]. The combination of the unique properties of silicones, such as high flexibility of Si–O–Si backbone, low surface tension, low intermolecular interactions, high UV transparency, and excellent
