Kaolin

Kaolin

Kaolin clay are inert, non-swelling, low oil absorption hydrous aluminum silicate minerals. Coupled with AMI’s mining and manufacturing processes and controls to make products with low grit content and low free moisture, they are well-suited to a wide range of industrial uses. Unlike other types of kaolins, AMI products are void of dispersants that can alter performance in some applications.

Kaolin Products

AMI produces several different types of air-float kaolin clay products:

Kaolin reinforcing fillers have a naturally fine particles size distribution (92%< 2 micron) and are commonly called “hard clays” as they provide reinforcing properties in a wide range of rubber compounds. In other applications – such as adhesives, caulks, sealants, driveway sealers, tape joint compounds, and more – they can provide general filling, lubricity, slight thixotropy, suspension and barrier properties. AMI’s popular grades are Acti-Min® RG, ChampionTM, Crown ClayTM  and SECCO ClayTM. 

Acti-Min® PG air-float kaolin reinforcing filler, our highest brightness product, is selectively mined and processed to provide greater TiO2 replacement and higher gloss and sheen control compared to water-washed kaolins – and at a lower cost. It’s most useful in paint coatings and primers that are off-white and tinted, high gloss coatings, white rubber compounds, sealants, and caulks.

Kaolin extender pigments have a coarser particle size distribution (86-54% < 2 microns) and are commonly called “soft clays” as they are excellent for high filler loadings and extending resins in foam rubber, other rubber compounds, adhesives, caulks and sealants. AMI’s popular grades are Acti-Min® RP-2RP-80SA-1 and WC-5.

Agricultural crop protection is well served by AMI kaolin products designed as pesticides, sun screens and as an inert diluent for pesticide and herbicide formulations. Acti-Min FE and Acti-Min Sunblock products form a kaolin mineral-based particle film barrier on leaves and fruit. Acti-Min FE kaolin is an EPA approved and OMRI listed pesticide for a broad spectrum  crop protectant for controlling damage from listed insects, mite, and disease pests. It also reduces environmental stresses caused by sunburn and heat stress. Acti-Min Sunblock product is OMRI listedIts finely-sized white kaolin particles are designed to provide greater coverage and work more effectively to scatter and reflect the sun’s rays. This reduces plant stress and minimizes sunburn, which leads to enhanced growth across a multitude of crops. It disperses easily in water and imparts low viscosity, which makes it ideal for spray applications. Acti-Min DX kaolin product is EPA registered as an inert ingredient for pesticide and herbicide formulations applied both pre- and post- harvest. It is a high quality, finely pulverized, low residue, air-float kaolin clay product. It is designed to serve as an economical diluent with low oil absorption and provide a low viscosity in liquids.

Another line of kaolin products is designed with highly controlled chemistries and top particle size, rather than particle size distribution. The consistent levels of high alumina and low iron and other oxides makes Acti-Min® FG-5 and Acti-Min CR ideal for use in making electronic grade fiberglass and white cement, respectively.

Kaolin Products

AMI air-float kaolin extender pigments and reinforcing fillers are used as raw materials in a wide range of industries, including fiberglass, adhesives, agricultural, ceramics, construction products, driveway sealers, paints & coatings, and roofing shingles. A brief description is given below.

Crop Protectants

Crop Protectants

ACTI-MIN® FE, Sunblock, DX

Acti-Min FE and Sunblock kaolin mineral products are crop protectants that form a particle barrier film on plants and their fruit.

Acti-Min FE kaolin product is an EPA approved and OMRI listed pesticide. It forms a particle film barrier that acts as a broad spectrum agricultural crop protectant for controlling damage from listed insects, mite, and disease pests. It also reduces environmental stresses caused by sunburn and heat stress that subsequently enhances growth.

Acti-Min Sunblock kaolin-based product is OMRI listedIts finely-sized kaolin particles are designed to provide greater coverage and work more effectively to scatter and reflect the suns rays. This reduces plant stress and minimizes sunburn, which leads to enhancesd growth across a multitude of crops. It disperses easily in water and imparts low viscosity, which makes it ideal for spray applications.

Acti-Min DX kaolin mineral product is EPA registered as an inert ingredient for pesticide and herbicide formulations applied both pre- and post- harvest. It is a high quality, finely pulverized, low residue, air-float kaolin clay product. It is designed to serve as an economical diluent with low oil absorption and provide a low viscosity in liquids.

Extender Pigments

Extender Pigments

Acti-Min® RP-2, RP-80, SA-1

Used in soft rubber applications at high filler loadings, such as computer mouse pads, automotive floor mats, toilet plungers, gaskets, bath mats, floor tiles and more.

Used at high filler loadings in caulks, sealants, mastics, tapes such as duct tape and surgical tape, grouts, asphalt coatings, joint compound, roofing granules, and ceiling tiles.

Reinforcing Fillers

Reinforcing Fillers

Acti-Min® PG & RG, Crown™, Champion™ & SECCO Clay™

Fine particle-sized kaolin clays are used as reinforcing extender pigments in foam rubber, automotive hoses and belts, shoe soles, wire and cable, rubber tires for lawn equipment, garden hoses, rubber floor mats and tiles. In gypsum wall board, Crown ClayTM provides lubricity reducing cracks from nails.

Acti-Min® RG grade is especially beneficial in extruded products. It’s very low +325 mesh residue minimizes particle agglomeration on the extruder’s screen packs.

Air-float kaolins are commonly used in certain enamel paints, primers, sealers and wood stains. They provide sheen and gloss control, enamel holdout, anti-settling and sanding properties. Acti-Min® PG grade is our highest brightness product. Combined with it’s very fine and narrow particle size distribution in the 0.25 micron range, PG has shown to be more effective at TiO2 extension in latex paint than higher cost water-washed kaolins.
