FREKOTE R-120
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Semi-Permanent Rubber-Mold Release Coating
- 4-Minute 150 deg C Cure
- Multiple Releases with Low Transfer
Product Description
LOCTITE® FREKOTE® R-120 is a one-part, water-based, semi-permanent release agent for rubber molding. Applied as a finely atomized spray to a preheated mold, it chemically bonds to the surface and forms a thin, inert, thermally stable release coating. The product supports natural and synthetic rubber polymers, including some thermoplastic urethanes, across mold application temperatures from 60°C to 200°C. It is intended for demanding molding processes where minimal mold buildup and low transfer to the molded part are required.
Key features
- Water-based formulation: Supplied as a translucent, non-flammable emulsion with mild odor.
- Semi-permanent release coating: Chemically bonds to a preheated mold surface to support multiple releases.
- Broad application-temperature range: Suitable for mold temperatures from 60°C to 200°C.
- Fast heat cure: Full cure time decreases as mold temperature increases, reaching 4 minutes at 150°C.
- Controlled mold condition: Recommended where minimal mold buildup and low transfer to molded parts are required.
Applications / Suitable for
- Natural and synthetic rubber molding
- Some thermoplastic urethane molding applications
- Demanding molding processes requiring minimal mold buildup
- Preheated molds operating from 60°C to 200°C
