Butonal® NX 4190

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, elastic recovery and softening point, over conventional cationic polymers.

A premium cationic SBR latex that provides excellent early strength development and adhesion for the following applications:

• Chip Seal

• Slurry seal

• Micro surfacing

Butonal® NX 4190 can also be used to modify hot mix asphalt in order to meet modified binder specifications as well as to provide improvements in conventional properties such as increased softening point and decreased penetration.
