Beschreibung
Zusammenfassung:	FIELD: chemistry.SUBSTANCE: invention can be used in production of paper, cardboard, wallpaper, plastic, concrete, ceramics. Composition for application on a substrate surface contains particles of echinoid shape consisting of a substance containing calcium carbonate, up to 250 wt% from the weight of the echinoid shape particles of at least one binder and from 0.1 to 10 wt% of the weight of the echinoid shape particles of at least one agent imparting hydrophobicity, and/or at least one agent imparting hydrophilicity.EFFECT: invention allows controlling wettability of surfaces from super-hydrophobicity to extreme hydrophilicity.27 cl, 17 dwg, 11 tbl Изобретение может быть использовано в производстве бумаги, картона, обоев, пластмасс, бетона, керамики. Композиция для нанесения на поверхность субстрата содержит частицы ежевидной формы, состоящие из вещества, содержащего карбонат кальция, до 250% масс. от массы частиц ежевидной формы по меньшей мере одного связующего средства и от 0,1 до 10% масс. от массы частицы ежевидной формы по меньшей мере одного средства, придающего гидрофобность, и/или по меньшей мере одного средства, придающего гидрофильность. Изобретение позволяет регулировать смачиваемость поверхностей от сверхгидрофобности до крайней гидрофильности. 4 н. и 23 з.п. ф-лы, 17 ил., 11 табл.
