MIN-U-GEL® attapulgite mineral products are used in liquid-based systems to stabilize the media, control flow and leveling, improve film build without sagging, and prevent settling and syneresis. It is a rheology modifier with thixotropic thickening. It also aids in the suspension of pigments to help prevent flooding and floating.


Min-U-Gel

Crown Clay is a high quality, air float, sedimentary, hard kaolin clay. Strict attention to production and quality control assures a high degree of product uniformity.


Crown Clay

Acti-Gel® high-performance additive will enhance nearly any concrete application. With the ability to eliminate segregation and reduce bleeding, it provides a pumpable, flowable, yet stable concrete product. From Self-Consolidating Concrete (SCC) to Concrete Paving, Acti-Gel 208 additive stabilizes the mix and improves workability which easily benefits any cementitious project.

Acti-Gel

Florigiel® rheology modifier is highly desired for use in oil well drilling mud, slurry trench walls and other geotechnical applications for its excellent stability in a salt or high ionic environment. It serves as an essential thixotropic thickener and suspension agent and meets API Specification 13A/ISO 13500.


Florigel

The high purity of Acti-Cast ECS product eliminates the extra processing steps used on ball clays to remove sulfur, lignite, excessive silica fines, and more. Slips made with Acti-Cast ECS plastic component do not need extended aging and constant adjustments. Batches can move more quickly to casting with predictable and consistent performance leading to higher yields and lower operating costs.


Acti-Cast

Acti-Min® is a clean, high quality, white-ring kaolin especially selected for the ceramic and refractories industries.


Acti-Min

Liquid Acti-Gel® is a high quality, purified magnesium aluminosilicate pre-dispersed in water and intended for high performance as a thixotrope, reinforcement additive and anti-settling agent in areas where the addition or metering of a liquid is preferable to using a dry powder.


Liquid Acti-Gel

Crown Clay is a high quality, air float, sedimentary, hard kaolin clay. Strict attention to production and quality control assures a high degree of product uniformity. Hard clays are very fine in their natural particle size. This limits how much hard clay can be incorporated into a rubber com-pound. Typical loading levels range from 20 to 150 phr. Hard clay provides high modulus, tensile strength, abrasion re-sistance, green strength and provides stiffness to elastomeric compounds.


Crown Clay™

MIN-U-GEL® 200 coarse grade is used in agricultural suspensions, such as liquid animal feed supplements, liquid suspension fertilizer, foliar sprays, and various ag chemicals such as wettable powders (WP), water-dispersible granules (WDG) and water-reducible (WR) pesticides. It is an EPA approved inert pesticide ingredient.

MIN-U-GEL® 200

Acti-Cast® AF is a white-firing coarse grained air-float kaolin specially selected for the Sanitaryware industry and other applications where a fast casting clay is desired. The product is controlled to maintain low deflocculation rates, low soluble sulfates and low sur-face area so that dewatering and plasticity remain consistent and predictable.


Acti-Cast® AF

Acti-Min® RG is a high quality, low residue, air floated sedimentary hard kaolin clay. Strict attention to production and quality control assures a high degree of product uniformity. Acti-Min RG is classified to a very low 325 mesh residue, making it suitable for any customers who may be sensitive to fine, non-kaolin residue.


Hard Clays are very fine in their natural particle size. They provide high modules, tensile strength, abrasion resistance, green strength and stiffness to elasometric compounds.


Acti-Min® RG

Liquid Acti-Gel® 208 is a high quality, purified magnesium aluminosilicate pre-dispersed in water and intended for high performance as a thixotrope, reinforcement additive and anti-settling agent in areas where the addition or metering of a liquid is preferable to using a dry powder.

Liquid Acti-Gel® 208

MIN-U-GEL 400 is a hydrous magnesium aluminum silicate with gelling and rheological properties used to thicken and stabilize aqueous systems. MIN-U-GEL® 400 can be used alone or in conjunction with associative thickeners where a low shear thixotrope is needed to support the high shear thixotropy of the associative thickener.


MIN-U-GEL® 400 was developed especially with controlled properties specifically to function as a binder during the production of molecular sieves.

Min-U-Gel® 400

Acti-Gel® 208 is a high quality, purified, self-dispersing hydrated magnesium aluminosilicate intended for high per-formance use as a binder, thixotrope, reinforcement additive and anti-settling agent.


Acti-Gel® 208

Florigiel® HY rheology modifier is highly desired for use in oil well drilling mud, slurry trench walls and other geotechnical applications for its excellent stability in a salt or high ionic environment. It serves as an essential thixotropic thickener and suspension agent and meets API Specification 13A/ISO 13500.


Florigel® HY
