Wetting Agents

In our prime coat slurry improvement studies, we screened many of the currently used non-ionic surfactants for effective wax wetting and low foaming characteristics. PS 9400 Prime Surfactant was chosen for its superior wetting properties that allow it to provide good coatings on even poorly etched wax patterns. It has good stability with colloidal silica and alumina slurries with low foaming action.

Anti-Foam

AF2004 is a 60%-active silicone emulsion designed for controlling foam in aqueous systems. It is effective in low concentrations.

AF9450C is a 10%-active silicone emulsion designed for controlling foam in aqueous systems. It is effective in low concentrations.

Polymers

Developed to improve green strength and adhesion of slurry coats to wax.

SBA is the optimal polymer for investment casting slurries. Polymer SBA unique physical properties result in higher green strength and tighter stucco adhesion.
