Forms of Kaolin
Slurry
Slurries are a mixture of water and kaolin clay.
Dispersants and pH modifying chemicals are added to optimize the
rheological properties of the slurry and maximize the solids. Slurry is
typically 60-70% solids.
Why Choose Slurry
- High volume WATER-BASED application
- Lowest cost kaolin form (drying eliminated)
- High shear dispersing not required – easy incorporation
- Zero dust
Spray Dried Beads
Kamin
LLC kaolin clays are dried through a process called spray drying. The
dispersed filter product is atomized into a heated environment. The
atomized droplets of clay form small beads that can be redispersed in
water under high shear. Beads can also be dispersed in high shear
polymer processing equipment.
Why Choose Spray-dried Beads?
- High shear dispersing equipment for water-based applications
- High shear polymer processing
- Higher bulk density to optimize loads and minimize warehouse space
- Low dusting, good powder flow
- Lower cost when compared to powder li>
Powder (Pulverized Beads)
Spray-dried
beads are passed through a milling device. The milling device
de-agglomerates the beads, but does not change the particle size
distribution.
Why Choose Powder?
- Solvent-based or 100% reactive coating, ink, or adhesive
- Water-based applications where product needs to be added directly to latex emulsions
- Minimal high shear mixing available
- Need a single
