Antifoam

Antifoam is a silicone-based antifoam, high-quality additive for precision investment casting use.

This water-based antifoam emulsion is specifically engineered to knock down foam and entrapped air in colloidal silica slurries, which helps prevent pinholes and air-related shell defects. Its low-silicone formulation disperses quickly and maintains slurry clarity without interfering with binder performance or drying time. Ideal for use in primary, intermediate, or backup coats, this additive keeps slurry viscosity stable and ensures cleaner shell builds. Foundries casting aerospace components, stainless steel parts, and industrial-grade pieces rely on this antifoam to improve slurry consistency, reduce rework, and maintain shell integrity.
