Latex Cement Composition

Manufacturer:  We use SBR or XSBR latex as bonding agent and gas block additives in the cementing section. The problem is the XSBR we recently purchased is difficult to mix into a fresh water cement slurry, despite large additions of naphthalene sulfonate dispersant.


John Woon (Senior Latex Consultant): You should try pre-stabilizing the latex with a non-ionic surfactant and Potassium hydroxide first before adding the cement slurry. If you are using Portland cement, switching to albuminous cement would help. Also, instead of using anionic latex, you could use cationic latex.
