Use of aqueous cationic dispersions of synthetic resins for impregnating and priming of absorbent substrates

Abstract From the Canadian patent

Use of finely divided aqueous cationic dispersions of synthetic resins obtainable by emulsion polymerization from suitable monomers and which contain cationic dispersion polymers as impregnants and primers for consolidating and priming or porous absorbent substrates, preferably inorganic substrates such as, for example, masonry, concrete, plaster surfaces gypsum, surfaces, bricks or wood by treating these substrates with the aqueous cationic dispersions whose polymer particles have mean particle diameters of 0.02 to 0.2 µm. Aqueous cationic dispersions of synthetic resins exhibit a superior penetrating and permeating power, in particular on smooth plaster surfaces and smooth gypsum …
