Abstract: A coarse particle kaolin clay is provided having an average Stokes equivalent particle diameter of about 4.5-6.0 microns, a BET surface area of about 8-11 m.sup.2 /g, and preferably having a median Malvern particle size of about 9.0-10.5 microns as determined by laser light-scattering measurement and a high aspect ratio preferably of about 12-14 as determined by Sphericity Model calculations. The coarse particle kaolin clay provides low viscosity build, good reinforcement properties and excellent surface finish qualities as a filler in thermoset composite materials, such as polyester molding compounds, and also provides excellent pigmenting properties in paints and industrial coatings. Preparation of the coarse particle clay involves blunging and degritting a crude kaolin clay, conducting three separate centrifugation steps with the desired product stream being, in sequence, the coarse underflow clay from the primary centrifuge, the coarse underflow from the secondary centrifuge, and then the fine overflow from the tertiary centrifuge, followed by magnetic separation, screening, chemical leaching, drying and milling to produce a kaolin clay product having the above-described physical properties and performance characteristics.

Abstract: An improved finely divided rubber-reinforcing clay mineral composition can be produced by employing a hydrous kaolin clay surface treated with a functional silane, a methylene donor compound such as hexamethylenetetramine, and a multifunctional methylene acceptor such as resorcinol. A novel process of preparation is provided. The improved reinforcing, treated clay filler can be combined with natural or synthetic elastomer compositions which can be cured to elastomer products which have improved physical properties, such as modulus, tensile, tear, wear resistance and/or resistance to heat build-up.

Abstract: This invention involves a method of optically whitening clay minerals to transform their natural yellow tint to increased whiteness. Generally, it has been found that clay materials having low cation exchange capability can be directly reacted with very small amounts of cationic dyes, the apparent whiteness of said clay minerals being substantially increased thereby.

Abstract: Sodium alumino-silicates are produced by silicate/clay reactions under hydrothermal conditions with increased solids during processing while still producing structural materials characterized by low oil absorption values, high total pore volume and increased differential pore volumes. The products are useful as coating pigments for paper and paperboard, paper fillers, paint pigments and as reinforcing pigments for rubber.

Abstract: A method and apparatus for calibrating or checking the calibration of vertical photometers. The invention may also provide easy and convenient assay results for diagnostic profiles. The invention comprises pre-dispensed amounts of a suitable reagent, chosen for the particular use, disposed in a vessel with an amount of a wetting agent or other means to yield a reproducible meniscus in the resulting control solution. The control solution is dried to leave a precise amount of dried reagent and other constituents in the vessel which can then be stored and distributed until subsequent use. The dried control solution can then be reconstituted to provide a standard having known absorbance and physical characteristics.
