Butonal® NS 175 is a mechanically stable latex polymer dispersion that improves the conventional properties of bitumen, e.g. higher softening point or lower penetration. In more complex rheological properties it improves stability and elasticity in the upper-use temperature range.
This product also improves the viscosity of the binder in hot mix asphalt, which consequently reduces the drain-down tendency. As a result, thicker bitumen film layers are obtained on the aggregates, which results in more stable matrix bonding and improved oxidative aging properties in the asphalt.

Butonal® NS 175 is suitable for hot mix asphalt (pre-blended and direct injection in pug mill) and as a latex polymer modification of anionic bitumen emulsions also for crack sealing or slurry seals.
