AQUEOUS COATING COMPOSITION CONTAINING POLYMER AND MODIFYING AGENT OF RHEOLOGICAL PROPERTY PREPARED BY POLYADDITION

摘要

FIELD: building materials. SUBSTANCE: invention relates to an aqueous coating composition containing mixture of from 90 to 99 wt.-% of composition of film- -forming binding agent containing alkaline non-swelling dispersion of type core-envelope obtained by polyaddition of polymer (I), 1-10 wt.-% of dispersion modifying rheological properties prepared by polyaddition of polymer (II). It is required that the total content of (meth)acrylic acid in 100 parts of polymer (I) prepared by polyaddition was less 1.75 wt.-%. An aqueous composition can be used as a basic layer/transparent layer. Such application is characterized by reducing effect of penetration inward as compared with the known system of basic layer/transparent layer. EFFECT: enhanced and valuable properties of composition. 13 cl, 5 tbl, 22 ex
