Product Description
LOCTITE® FREKOTE® FMS is a clear, colorless, solvent-based polymeric mold sealer formulated for fiberglass-reinforced polyester, epoxy, and other composite molds. Applied by wiping during mold preparation, it seals microporosity and slight surface imperfections to create a uniform base for subsequent mold release-agent application. The room-temperature-curing sealer is particularly relevant for new or “green” molds and repaired areas, providing a high-gloss surface with straightforward application and a 20-minute final-coat cure at 20°C.
Key features
- Composite mold sealing: Formulated for fiberglass-reinforced polyester, epoxy, and other composite molds.
- Microporosity control: Seals microporosity and slight surface imperfections in new, green, or repaired molds.
- High-gloss preparation: Produces a high-gloss mold surface and supports uniform release-agent application.
- Wipe-on application: Applied using a clean, lint-free cotton cloth.
- Fast room-temperature cure: Final coat cures in 20 minutes at 20°C.
Applications / Suitable for
- Fiberglass-reinforced polyester molds
- Epoxy and other composite molds
- New or green molds with microporosity
- Repaired mold surfaces and areas with slight imperfections
- Mold preparation before applying a compatible release agent
