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. rnCombination of the unique properties of silicones pressure-sensitive adhesives, such as high Si–O–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.rnSelected 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).rnThe 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.rn
Vitaly Ovchinnikov was awarded his PhD in 1989. He was recognized by the Cambridge Biographical Centre among the 100 Top scientists of year and 2000 Outstanding Intellectuals of the 21st Century in the year 2012. He has expertise in thermodynamics and thermo-chemistry, reactivity of hetero-atomic compounds in differed useful areas such as hydrocarbons, nitro compounds, carbohydrates and amino acids of different structure.

He was a member of American Chemical Society and was awarded Honored Worker of a Science of Republic Tatarstan (in Russia). He is currently serving as a member of Editorial Boards of American Journal of Physical Chemistry, Journal of Chemical Engineering and a reviewer of Journal Advances in Natural Science (Canada).
The values of free energies and the heats of combustion and formation in condensed and aqua phases of some amino acids of different structure and some peptides of the low molecular weight were analyzed on the topics of their interactions each to other and hydrolysis decomposition. The equation of such type as Hо = i ± f (N – g), in which Hо is the heat, i and f are stoichiometric coefficients, N is the number of valence electrons, from which a number of lone electron pairs (g) is excepted for, has been made. The obtained equation were used for the calculations of a new such parameters for four amino acids in water continuum.
