Rheofalt® WKR-2 

Rheofalt® WKR-2 is a premixed ethylene vinyl acetate copolymer consisting of resins and antioxidants to improve the service life and stability of asphalt mixtures that are introduced directly into the asphalt mixer. It can also be added to the bitumen storage tanks to create a polymer modified binder (PmB) without the need for a high shear mixing.

Rheofalt® WKR-2 is specially designed for low shear and fast dispersion in the asphalt mixture.
