Design of chemically resistant coatings using secondary raw materials and hazardous waste
Stodolovská, Šárka ; Jakubík, Aleš (referee) ; Drochytka, Rostislav (advisor)
On the basis of theoretical knowledge gained from Czech and foreign technical literature, two types of coatings using fillers based on secondary raw materials, including hazardous waste, is designed and experimentally verified. The expected use of the proposed coating systems, both PREMIUM and ECOLOGY, is the protection of building structures that are permanently stressed by increased chemical stress. When designing the PREMIUM coating material, emphasis is primarily focused on chemical resistance and functional parameters, and the ecological performance of the raw materials used is monitored primarily with the ECOLOGY coating material. In both cases, it is important to maintain a favorable price / value ratio.

Design of vapor proof protective coating for concrete with chemical resistance
Fousková, Marika ; Hodná, Jana (referee) ; Drochytka, Rostislav (advisor)
The main content of the bachelor's thesis is to design a vapor-tight chemically resistant coating using secondary raw materials. Coatings are applied primarily for the purpose of protecting concrete structures that are exposed to chemical stress. Secondary raw materials are used in the coating in the form of a microfiller, which is evenly dispersed in the polymer matrix. The proposed coatings show high adhesion to concrete, excellent workability and applicability, while the filler in the form of secondary raw materials does not impair the properties of the coating, both in fresh and polymerized state.

Crystallization of coating systems based on epoxy resins.
Seidlová, Michaela ; Dohnálek,, Pavel (referee) ; Petránek, Vít (referee) ; Drochytka, Rostislav (referee) ; Bydžovský, Jiří (advisor)
Crystallisation of epoxy resins based on bisphenol A and bisphenol F is the natural property of these oligomers. However, manufacturers of paints and other systems based on these epoxy resins, strive to slow down the crystallisation process as much as possible, thereby prolonging the shelf life and improving the competitiveness of their products. The main aim of the thesis is generalisation of the factors influencing the crystallisation process of epoxy resins based on bisphenol A and bisphenol F, verifying new approaches to the possibility of influencing the crystallisation process and determining the possibility of using a certain degree of epoxy resins crystallinity based on bisphenol A and bisphenol F in the preparation and production of epoxy resinbased coating systems.
