- 4-Minute 149 deg C Cure
Product Description
LOCTITE® FREKOTE® R-220 is a one-part, water-based, heat-curing mold release emulsion for demanding rubber molding processes. Its high-slip characteristics make it particularly relevant for difficult-to-release materials such as EPDM and highly filled elastomers. Applied as a finely atomized spray to a preheated mold, the product chemically bonds to the surface and forms a thin, inert, thermally stable release coating. It also supports thermoplastic urethanes and solid polyurethane cast elastomers across mold application temperatures from 60°C to 205°C.
Key features
- High-slip release performance: Formulated for difficult-to-release rubbers, including EPDM and highly filled elastomers.
- Water-based formulation: Supplied as a non-flammable, milky-white emulsion with mild odor.
- Heat-cured coating: Chemically bonds to preheated mold surfaces to form a thin, inert release layer.
- Fast application and cure: Multiple coats can be applied to the heated mold, with full cure in 4 minutes at 149°C.
- Gloss finish: Produces a gloss finish under the documented application conditions.
Applications / Suitable for
- EPDM and other difficult-to-release rubber compounds
- Highly filled elastomers
- Thermoplastic urethanes
- Solid polyurethane cast elastomers
- Preheated molds operating from 60°C to 205°C
