  • Reflective composition of particles with resinous binder and process for preparing same
    Patent number: 6166123
    Abstract: A method of manufacturing powder coating compositions, the powder coating compositions, and cured coatings made from the coating compositions are described. The method of preparing the coating compositions comprises combining a preformulated thermally softenable resin powder (having a defined T.sub.g) and a reflective pigments (such as a non-leafing or leafing metallic flake, mica, optically variable pigment, and the like) and then mixing the powder and flake under high shear conditions and assuring that the average temperature of the mixture remains below the T.sub.g of the resin during the high speed mixing process.

  • Reflective composition of particles with resinous binder and process for preparing same
    Patent number: 6162856
    Abstract: A powder coating, and a method for manufacturing a powder coating that includes high-shear mixing of powdered binder and powdered pigment while controlling the temperature of the mixture within the range between the softening temperature and the glass transition temperature of the binder or first below the glass transition temperature and then above the glass transition temperature of the binder.
