Abstract:

Pressure sensitive-adhesives (PSA) can be defined as a special category of adhesive which are used for the production of a variety of materials, such as mounting tapes, labels, protective films, masking tapes, operations tape and biomedical electrodes. Combination of the unique properties of silicones pressure-sensitive adhesives, such as high Siâ??Oâ??Si backbone flexibility, low intermolecular interactions, low surface tension, excellent thermal stability and high UV transparency, often explains why silicone PSAs have superior performance at high- and low-temperature extremes, excellent electrical properties, chemical resistance and outstanding weathering resistance. It makes they superior compared to organic PSAs. Selected silicone PSA composition with crossilinking agent was mixed with filler to obtain homorganic composition containing 50 wt. % polymer. Nanokaolin was add in 1, 3, 5, or 7 wt.% on a base of polymer content. Subsequently, PSA was coated (coating speed 5 cm/s, coating weight 45 g/m2) on polyester film (50 μm), dried for 10 min at 110°C in drying canal. Thus obtained adhesive films were secured with a polyester film (36 μm). The presented on the poster self-adhesive tapes based on PSA with nanokaolin characteristic good mechanical properties and improve thermally resistance. The best mechanical properties showed of compositions adhesive Q2-7566 with kaolin. The highest maximum temperature work (ca. 246 ºC) obtained composition PSA 590 1,5 wt.% with 7 wt.% content of kaolin. Tape based on silicone PSA with kaolin could be used in heavy industry to combine elements operating at elevated temperature or aerospace bonding solar cells on board satellites and space stations.
