15 Driers brand ATTDRY for alkyd coatings — Ju. V. Galkina
A wide range of alkyd resins, one metal and combination driers were considered. Using different combinations of resins and driers were developed protective coating and after drying were tested. Found that primers and enamels have high protective properties and are recommended for painting
various metal structures.
Keywords: alkyds, drying agents, protective coatings

20 ALTIRIS — titanium dioxide by HUNTSMAN PIGMENTS & ADDITIVES (VENATOR) for special purpose — L. Yu. Businer
Offered a new brand of titanium dioxide to create a heat reflective coating instead of pigments named cool colors. Investigations of particle size
and distribution for very high refl ectance of solar radiation in the infrared range in comparison with pigment titanium dioxide were carried out. In addition to excellent reflective properties, the new pigments extend the life of coatings as they are much more resistant to photochemical degradation.
Keywords: titanium dioxide, reducing power, heatreflecting coating

METHODS OF TESTING

30 Topological method of calculating the composition of polydisperse mixtures of fillers and forecasting the properties for decorative
finishing — N. N. Furman
With the help of topological methods, the packing density and the optimal composition of compacted polydisperse mixtures consisting of several grades of micromaramor with different average particle diameters are calculated. A formula is proposedfor calculating the critical volume concentration of pigments and fillers. A formula is proposed for calculating the volumetric concentration of pigments with the minimum possible amount of binder. A method for calculating the specific surface area of the filler is proposed. The influence of the packing density, the specific surface of the filler and the size of the binder micelles on the magnitude of the critical volumetric concentration of pigments and fi llersin paint and decorative materials is shown.
Keywords: specifi c surface area, the pigment critical volume concentration, the packing density
