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.

Latex polymer modification of cationic bitumen emulsions, particularly suitable for the following applications:

• Chip Seal

• Slurry seal

• Micro surfacing

• Tack coat

• Open and dense-graded cold mixes

• Cold-patching material

• Emulsion crack filler

Butonal® NS 198 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.
