Butonal® NX 4190

Butonal® NX 4190 is a mechanically stable latex polymer dispersion that is readily incorporated into cationic asphalt emulsions when added to the soap solution (batch process) or co-milling (continuous process). Butonal® NX 4190 provides excellent cohesion and adhesion properties with aggregate and significantly enhances the residue properties such as forced ductility, toughness and tenacity, elastic recovery and softening point compared to conventional cationic polymers.
