Abstract: A multi-component pigment slurry which comprises at least 50% solids. The slurry is formulated to be admixed into paint and coating compositions to promote TiO.sub.2 extension. The slurry includes a structured pigment, a coarse particle size pigment, and a fine particle size pigment. The structured pigment comprises about 20% to about 55% of the slurry by dry weight and has a median particle size diameter of about 0.7.mu. to about 6.0.mu.. The coarse particle size pigment preferably comprises about 20% to about 60% by weight of the slurry and has a median particle size diameter of about 3.0.mu. to about 10.0.mu.. The fine particle size pigment preferably comprises up to about 50% by dry weight of the slurry and has a median particle size diameter of about 0.2.mu. to about 1.0.mu..

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: High performance synthetic sodium aluminosilicate compositions, and the method of making the same by the hydrothermal reaction of certain delaminated kaolin clays with select sodium silicate reagents, result in enhanced performance flatting agents for paint systems and anti-block agents for plastic film applications.

Abstract: The present invention relates to slurries of synthetic alkali metal silicates with fine particles kaolin clay. The slurries consists of at least 50% solids which solids comprise an approximately 50:50 combination of the fine kaolin clay and the synthetic alkali metal silicate (SAMS). The integrated composition of the SAMS products is an entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is an alkali metal, y is the number of miles of SiO.sub.2 in the unique SAMS composition, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The composition essentially comprises altered kaolin clay platelets with an integral rim or protuberance of essentially amorphous alkali metal silicate-kaolin reaction product. The slurry is useful in latex paint systems.
