Abstract: A paper coating pigment manufactured from kaolin crude containing minor amounts of minerals is used in lightweight coated and ultra-lightweight coated applications. The pigments comprise a phyllosilicate assemblage of minerals that yield a final pigment MgO content ranging between 0.04 to 0.3 weight percent and a K2O content ranging between 0.12 and 0.8 weight percent based on the dry weight of the kaolin crude. The mica in the pigment product is 1.0% to 6.7% by weight, and smectite is 1.2% to 9.1% by weight of the kaolin. The presence of these weight percentages can be identified by a shape factor of 15 or greater. The viscous clay content of the feed to produce the pigment product is between 70 and 100 weight percent based on the dry weight of the kaolin clay. The pigment has a shape factor ranging between 35 and 60 or greater, and greater than 80% by weight of the particle are less than 2 microns, and greater than 12% are less than 0.25 microns.

Abstract: A cooling device for a brake component is provided. The brake component includes a structural element that has an interior cavity. A cooling material is disposed within the cavity. The material has a phase change temperature at a particular pressure and volume. The material absorbs the heat generated by the structural element by changing from a first state to a second state at the phase change temperature to maintain the brake component or structural element below the maximum operating temperature. The phase change temperature may be defined by a melting point of the material in which the first state is solid and the second state is liquid, or by an evaporation point of the material in which the first state is liquid and the second state is gas.

All adhesives used in the process are cold glues applied without using heat, through an extrusion and/or metering application means. Cellulose film is used for the paper liner and dot matrix configuration of adhesive is applied between the cellulose and paper layers for lamination.
