DESCRIPTION:
Modified asphalt is used in electrolytic aluminum industry to produce pre-baked anode blocks, manufacture high power electrode rod, also can be used as electrode adhesives.
Modified Pitch is obtained from powerfully processed coal tar. Compared to petroleum asphalt, the adhesiveness is better. Modified Pitch is high quality tar production with high fixed carbon. It has excellent adhesion, waterproofing and resistance against seawater, oil and various chemicals. In these properties, it is much better than petroleum asphalt tar.
