BUTONAL® NX 4190

Proven performance in asphalt modification

BUTONAL NX 4190 is a mechanically stable latex polymer dispersion that is readily incorporated into cationic asphalt emulsions through addition 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, torsional recovery, and softening point over conventional cationic polymers. BUTONAL NX 4190 is recommended for use in chip sealing, micro surfacing, and slurry seals.
