  • Method of reducing binder demand of inorganic filler
    Patent number: 4257817
    Abstract: The binder demand of particulate inorganic filler is reduced without essentially altering the filler's surface area by subjecting the filler alone to intense rotary impact agitation at a peripheral speed of from about 20 to 60 meters per second. Compositions comprising a binder together with a filler prepared by this method include those in which the binder comprises alkyd resin, especially an unsaturated polyester resin, epoxy resin or linseed oil and the filler comprises ground limestone, talc or hydrated alumina.
