  • Slip coating chaff
    Patent number: 4649076
    Abstract: A method of providing a slip coating on aluminized glass fibre chaff is provided in which the chaff is treated by applying a boundary lubricant dispersed within an aqueous medium, the boundary lubricant containing free palmitic acid and ammonium palmitate. The aqueous medium forms a hydrated aluminum oxide on the surface of the chaff and promotes a reaction between the surface oxide and the palmitic acid to provide a chemically bonded surface slip coating layer of aluminum palmitate.
