Butonal® NS 198

Butonal® NS 198 is a mechanically stable latex polymer dispersion that is readily incorporated into cationic bitumen emulsions through addition to the soap solution (batch process) or co-milling (continuous process). It enhances cohesion and adhesion properties with aggregate and residue properties, e.g. forced ductility, elastic recovery, and softening point.
