  • Patent number: 5961730
    Abstract: An asphalt release agent for preventing hot road asphalt, especially polymer-modified asphalt, from sticking to surfaces of delivery truck beds is provided. The release agent includes a water-based mixture of polycycloaliphatic amines and polyalkylene glycols. The release agent is applied onto the truck beds to create a slippery non-stick surface so that the road asphalt which comes in contact with such truck bed surfaces will not adhere.

  • Patent number: 5922663
    Abstract: A composition comprising a conventional surfactant, a gemini surfactant and a polymeric soil release agent. The conventional surfactant comprises a hydrophilic group and a hydrophobic group. The gemini surfactant comprises two surfactant moieties attached to each other by a spacer moiety; each surfactant moiety having at least one hydrophilic group and at least one hydrophobic group. The polymeric soil release agent can be any conventional polymeric soil release agent, but preferably comprising PET-POET copolymer. The compositions are useful as surfactant additive packages, detergents and fabric softeners.
