LOCTITE FREKOTE 55NC is a semi-permanent mold release agent formulated to build a durable, conditioned release film for composite tooling. Buyers sourcing mold release systems for FRP, marine, and pultrusion production use LOCTITE FREKOTE 55NC when they need multiple releases per application without constant reapplication.
Physical Properties
Before specifying a release agent, buyers should confirm the resin properties below against the current Safety Data Sheet for their production environment.
| Property | Typical Value |
|---|---|
| Specific Gravity @ 25°C | 0.715 to 0.725 |
| Flash Point | See SDS |
Application Method
This release agent can be sprayed, brushed, or wiped onto mold surfaces at room temperature up to 60°C using a clean, lint-free cloth. Spraying should be done with a dry air source or an airless spray system, and the work area should be kept well ventilated throughout application. Operators should apply a smooth, thin, continuous wet film and avoid recoating an area until the solvent has fully evaporated; for spray application, the nozzle is typically held 20 to 30 cm from the mold, moving progressively across small sections of the surface.
A standard schedule calls for 2 to 3 base coats, spaced 5 minutes apart to allow solvent evaporation, followed by a 30-minute cure at 22°C before use. Release performance continues to improve as the mold becomes conditioned with repeated use, and operators can strengthen film build by applying one additional coat after the first few production pulls.
Storage and Handling
Because this product is moisture sensitive, containers should remain tightly closed between uses and stored in a well-ventilated location. For closed mold processes such as rotomolding, operators must confirm that all solvent has evaporated and vented from the cavity before sealing the mold; oil-free compressed air can help accelerate this evaporation and ventilation step.
Why Sourcing Consistency Matters
Variations in solvent content or cure timing between batches of release agent can cause uneven demolding, surface blemishes, or unplanned line stops in FRP pipe and tank, marine, and pultrusion operations. Working with a supplier that documents packaging and COA information for every shipment helps buyers keep mold-release performance consistent across production runs.

Documentation
Buyers should request the current Technical Data Sheet and Safety Data Sheet for LOCTITE FREKOTE 55NC before adding this product to a mold-preparation workflow, to confirm coat schedule, recommended cure times, and handling requirements for their specific mold materials and production environment.
Frequently Asked Questions
What makes LOCTITE FREKOTE 55NC a semi-permanent release agent?
It builds a conditioned film on the mold surface through repeated coats, allowing multiple part releases before reapplication is needed.
How long should each coat cure before demolding?
The final coat should cure for 30 minutes at 22°C after 2 to 3 base coats applied with 5-minute intervals between each.
Can this release agent be used in closed mold systems like rotomolding?
Yes, provided all solvent has evaporated and vented from the mold cavity before closing, assisted if needed by oil-free compressed air.
Where can buyers get sourcing support for LOCTITE FREKOTE 55NC?
Buyers can request current TDS and SDS documentation and reach out through Thousands Technology’s supply chain resource support for guidance on this and related mold release products.
