Abstract:
A hydrous kaolin clay slurry mixture comprising:a) a volume of an aqueous slurry of the hydrous kaolin clay having an amount of hydrous kaolin clay ranging between 40 and 70% by weight of slurry, the amount of kaolin clay in the volume of the aqueous slurry further comprising a dry weight of hydrous kaolin clay; andb) a functional silane emulsion comprising:i) a functional-silane containing dispersion wherein the functional silane is selected from the group of a sulfur functional silane and a vinyl functional silane, wherein a concentration of the functional silane in the dispersion ranges between about 35 and 60% by weight, wherein the amount of the functional silane in the dispersion is based on the dry weight of the hydrous kaolin clay such that an amount of the sulfur functional silane in the dispersion equates to between about 0.7 and 5.0% by weight based upon the dry weight of the hydrous kaolin clay in the aqueous slurry and an amount of the vinyl functional silane in the dispersion equates to between about 0.2 and 5.0% by weight based upon the dry weight of the hydrous kaolin clay in the aqueous slurry; andii) a surfactant in an amount ranging between 0.5 and 10 parts by weight based on 100 parts by weight of the amount of the functional silane.
