WACKER® GM 196

Release agents make three important functions in the die-casting process possible:

• Formation of a lubricating film between the mold and the molt metal
• Formation of a parting film between the mold and the casting
• Cooling of the mold

Water-based release agents formulated with WACKER silicones are proven solutions for these tasks. In addition, our newest grades represent a superior solution for higher casting temperatures. In more complex or bigger molds, the molten metal is introduced at even higher temperatures to ensure good flow into undercuts, cavities or complex shapes. The new WACKER® GM 196 provides a higher amount of active content (~30%) at temperatures above 450°C for excellent release and lubricating properties.

Release actives at high temperatures

WACKER® GM 196 provides more active content at higher temperatures than reference products.

WACKER® GM 196 was developed for the formulation of release agents for the thermal molding of rubber, plastics, and low melting non-ferrous metals. Its chemical structure imbues it with the benefits of silicone fluids and mineral oils. WACKER® GM 196 is especially recommended for the formulation of release agents which are applied at very high temperatures of the die. An outstanding release effect is even obtained when extremely small amounts of WACKER® GM 196 are used.

WACKER® GM 196 is an organomodified silicone fluid also available as WACKER® E 3196, a silicone fluid emulsion with a 50% solids content. Both products stand out with approx. 15% higher active content at elevated temperatures compared to standard market products.
