Styrene-Butadiene Latex - MCPolymers

Sep 01, 2015 · Styrene-butadiene latex differs from SBR due to its greater crosslink density. This attribute gives the styrene-butadiene latex offering more toughness and strength, as well as elasticity, compared to artificial rubber. Styrene-butadiene rubber, for further context, is much stronger than natural latex.

Measuring the effects of styrene butadiene copolymer latex ...

It is a surfactant-stabilized styrene–butadiene copolymer latex used in , mortar, grout, and cement mixtures; when used properly (mixed well before and after use), it can produce mixtures that exhibit improved adhesion to most substrates, improved water resistance, increased flexural strength, increased resistance to freezing/thawing and wetting/drying cycles, and reduced water/cement ratios.
