Wilco-SLU
Wilco SLU is an aqueous suspension of kaolin produced at 70% solids content. The slurry is deflocculated and rheology stabilized with sodium silicate. The Wilco SLU grade is a highly permeable selection and recognized for its coarse particle size distribution. In a ceramic casting formulation, it offers fast casting rate for reduced casting times and quick firming of the piece upon drainage of the mold and removal of the piece for drying.

Wilco-LPC
Wilco LPC is the same selection as the SLU grade except it is in natural shredded or Airfloat (powdered) form. It offers the same benefits in a ceramic casting formulation discussed above for the SLU product.

Wilco-UPF
Wilco UPF is finer grained kaolin and can be employed in a ceramic formulation where higher permeability type kaolin is not required. It has excellent suspension qualities and lends good film strength to ceramic engobes and glazes of all temperature ranges.  Wilco UPF also meets the requirements of filler applications where a dry ground processed kaolin can be employed.
