Batimix WPR Series

Water-repellent additives for Portland and masonry cements


BATIMIX WPR Series products are aqueous solutions of insoluble stearate chemicals and carboxylic acids designed for use in the manufacture of Portland and masonry cement types.

BATIMIX WPR Series products impart water repellency in the cement paste matrix. They build a matrix of insoluble water-resistant material within the pores of the cement paste. They form an effective internal barrier that prevents water transmission. These additives are effective in both open and closed circuit cement mills.
