34 Silica gel antiseptic filler for water-dispersion paints — Prof. Dyachenko A. N., Candidate of Chem. Sci. Dyachenko E. N.
Abstract.
A new fluoroammonium method for producing silica filler for water-dispersion paints has been studied. The initial raw materials for production can be natural silica, sand, quartz, and other minerals with a high (>90%) silicon oxide content. Batches of precipitated silicon oxide with different moisture content and residual content of fluorine ion in the form of ammonium hexafluorosilicate, which is a good antiseptic, were experimentally obtained.
Keywords: silicon dioxide, silica gel, aerosil, ammonium fluoride.

40 Concrete products, especially «new» ones, also ask for protection with coatings — Candidate of Tech. Sci., Associate Prof., Voitovich V. A., Candidate of Tech. Sci, Prof. Khryapchenkova I. N.
Abstract.
The article provides information about the need to protect hardening concrete from water loss with coatings. Currently, their range is small, the quality is insufficient. Better representatives of them are required. An overview of the currently used materials and a recommendation for their improvement are given.
Keywords: concrete, hardening, prevention of water loss, coatings.

49 Influence of mineral fillers on the properties of photocurable compositions — Tikhomirova A. O., Candidate of Chem. Sci. Kostitsyn A. V., Bespokoev A. S., Prof. Indeykin E. A.
Abstract.
A study of the influence of mineral fillers on the curing process of UV- compositions was carried out. Data on the kinetics of UV- curing were obtained based on dynamic-mechanical analysis and DSC photos. The density of cross-links for the studied compositions was calculated. The influence of the photoinitiator on the curing process with various fillers has been established.
Keywords: nepheline syenite, microtalc, UV- curing, fillers, thermal effect, cross-link density, absorption spectra, unsaturated polyester.
