Butonal® NX 1129

Butonal® NX 1129 is a novel latex polymer dispersion designed to be mixed with hot mix asphalt to produce a highly elastic modified binder with long-term storage stability. It can be used to modify hot mix asphalt in order to meet modified binder specifications as well as to improve conventional properties, such as a higher softening point and lower penetration. Butonal® NX 1129 can also be incorporated into anionic bitumen emulsions via addition to the soap solution (batch process) or co-milling (continuous process).
