MasterCast 141 is a white liquid (SBR) styrene-
butadiene co-polymer latex, specifically designed
for use with Portland cement mixes. The latex
consists of microscopic particles of synthetic
rubber dispersed in an aqueous solution. It is used
as an admixture in mortar and concretes to
improve compressive and flexural strengths,
improve bond increase resistance to water
penetration, improve abrasion resistance and
durability. It is used with Portland cement as a
reliable water-resistant bonding agent.
