Features Of Wacker GM 171 Silicone Fluid Emulsion Mold Release Agent

  1. Water-based silicone emulsion offering excellent release performance without solvent emissions.

  2. Provides uniform, non-stick film formation on complex mold surfaces for consistent part ejection.

  3. Compatible with both cold and warm molds, supporting flexible processing temperatures (15–80 °C).

  4. Low foaming formulation ensures stable application in automated spray or dip systems.

  5. Non-yellowing and chemically inert—preserves substrate appearance and avoids interference with downstream painting or bonding.

Typical Applications Of Wacker GM 171 Silicone Fluid Emulsion Mold Release Agent

  1. Release agent for polyurethane (PU) foam manufacturing—including flexible slabstock and molded foams.

  2. Demolding aid in thermoset composite production, such as fiberglass-reinforced plastics (FRP) and SMC/BMC.

  3. Surface treatment for rubber molding processes, including EPDM, silicone, and natural rubber compounds.

  4. Release solution for gypsum, plaster, and cementitious precast concrete molds.
