  • Accelerator-gel additive for use in the production of polymer modified asphalt
    Patent number: 6569925
    Abstract: The present invention is directed to a an accelerator-gel additive used to deliver an accelerator such as sulfur, into a system for the production of polymer modified asphalt, vulcanized rubber or similar system. Unlike conventional methods of delivering accelerator into the system, the accelerator-gel additive suspends the accelerator in a gel system thereby preventing the sedimentation of the accelerator during processing. As a result, the polymer and asphalt are processed at lower temperature reducing the production of toxic and flammable gases such as hydrogen sulfide.
