Sbr latex for asphalt

SBR Latex Polymers – ULTRAPAVE®

ANIONIC SBR LATEX POLYMERS (For Polymer Modified Asphalt) (**Values are typical and not meant to be specifications.) Heat and mechanical agitation with time produce a homogenous blend of polymer in the asphalt. As the latex is added, the polymer particles swell from the heat and solvating effects of the resins and oils in the asphalt.
