  • Alkenyl succinic anhydride emulsion
    Patent number: 5176748
    Abstract: In sizing paper and paperboard with an aqueous ASA sizing system, a dispersal is formed comprising an ASA, a water-immiscible carrier, and a cationic water-soluble dispersing agent and when desired, a non-ionic surfactant. The dispersal can be shipped and stored for a prolonged time until use. The dispersal is added to water to form an oil-in-water sizing emulsion. This prepared emulsion is suitable for sizing paper and paperboard directly without the need for additional emulsifying agents or expensive equipment.

  • Phospholipid lubricant for coating moving webs
    Patent number: 4766015
    Abstract: Phospholipids such as lecithins provide improved rheological properties for coating a rapidly moving web, such as a paper web. The phospholipids are preferably applied to the paper web as part of a coating mixture, and they can be included in the coating mixture by first including the phospholipid in a lubricant additive mixture that includes an emulsifier, a fatty acid vehicle, and plasticizer. The lubricant is well-suited for short-dwell coating methods.
