Mold Release Agent
A non-ionic water-based emulsion designed for effective mold release in cast polyurethane elastomer applications, providing multiple releases per application with clean surface finish and broad material compatibility.
Mold Release Agent a high-performance non-ionic silicone emulsion specifically designed for use as a mold release agent in cast polyurethane (PU) elastomer applications. It provides excellent release properties, surface finish, and mold protection without interfering with curing or post-processing operations.
The non-ionic nature ensures broad compatibility with PU systems, pigments, fillers, and additives, while minimizing surface defects, buildup, and transfer.
- Cast polyurethane elastomers
- PU rollers, wheels, bushings
- Industrial PU parts
- Metal molds
- Epoxy molds
- Silicone and composite molds (after compatibility check)
How to use RXSOL Mold Release Agent
- Clean mold thoroughly before first use
- Dilute product with clean water as recommended
- Apply by: Spray or Brush
- Wipe with lint-free cloth
- Allow to dry completely before casting
- Reapply as required based on cycle count
- Polyester-based PU systems
- Polyether-based PU systems
- Filled and unfilled formulations
- Not recommended to mix directly into PU resin
- Compatibility testing advised before large-scale use
Dilute the product using water with a hardness not exceeding 250 ppm (expressed as CaCO₃), adjusting the dilution level according to the intended application technique, such as spray or pad application. The molds should be completely clean before treatment. Typically, one treatment with Mold Release Agent will remain effective for two to ten molding cycles, depending on the design complexity of the mold and the type of material being molded.
