Features Of Wacker GM171 Silicone oil emulsion mold release agent

  1. High-performance silicone oil emulsion offering excellent demolding efficiency on complex geometries and textured surfaces.

  2. Water-based formulation ensures low VOC content, improved workplace safety, and easy cleanup with water.

  3. Thermally stable up to 200 °C, maintaining film integrity during high-temperature curing cycles.

  4. Non-staining and residue-minimizing—preserves surface finish of molded parts without interfering with downstream painting or bonding.

  5. Compatible with automated spray systems and dip-coating processes for consistent, reproducible application.

Typical Applications Of Wacker GM171 Silicone oil emulsion mold release agent

  1. Release agent for unsaturated polyester (UP) and vinyl ester resin composites in FRP manufacturing.

  2. Mold release in pultrusion and RTM (Resin Transfer Molding) processes for structural profiles and automotive components.

  3. Demolding aid for gypsum, concrete, and plaster casting molds in architectural precast and decorative elements.

  4. Surface treatment for rubber and thermoplastic elastomer (TPE) molding to reduce sticking and improve cycle time.

  5. Release solution for polyurethane foam production—including slabstock, molded, and integral skin foams.
