Consistent release performance is essential for protecting finished parts, reducing mold cleaning, and supporting stable production cycles. LOCTITE FREKOTE 55-NC Mold Release Agent forms a non-migratory coating that remains on the mold rather than transferring to the molded component. This characteristic helps minimize surface contamination and supports downstream finishing, bonding, painting, or coating processes when the complete manufacturing procedure has been properly validated.
The clear, colorless liquid is designed for epoxies, polyester resins, thermoplastics, adhesives, advanced composites, FRP polyester parts, and rotationally molded plastics. After curing, the film offers thermal stability up to 400°C under specified conditions, allowing it to perform across many elevated-temperature molding processes. The product also helps reduce mold build-up, which can lower cleaning frequency and improve productivity.
This release coating is suitable for composite molds used in aerospace parts, automotive panels, marine components, sporting goods, wind-energy components, industrial housings, fiberglass products, and precision molded assemblies. It is particularly useful where multiple releases, a clean part surface, and a consistent satin-matt appearance are required.
The product may be applied to mold surfaces from room temperature up to 60°C. Manufacturers can wipe it on with a clean lint-free cloth, apply it by brush, or spray it using dry air or an airless system. This flexibility allows production teams to select an efficient method for complex tooling, large molds, detailed cavities, and routine touch-up work.
LOCTITE FREKOTE 55-NC Mold Release Agent offers fast drying between coats, non-contaminating release, high thermal stability, and no CFC content. Its semi-permanent technology supports multiple demolding cycles while helping prevent excessive polymer accumulation on the tool. Because only thin, continuous coats are required, users can control material consumption and maintain a smooth mold surface.
The coating also supports targeted maintenance. Touch-up coats can be applied only where reduced release performance is observed, helping limit unnecessary product use and lowering the risk of release-agent build-up.
Mold surfaces must be completely clean and dry before application. Remove old release materials, grease, dust, resin residue, and other contamination. New, repaired, fiberglass, or epoxy molds should be fully cured and sealed with an appropriate mold sealer when required.
Apply two to three thin base coats, allowing approximately five minutes between coats for solvent evaporation. Avoid repeatedly wiping or spraying the same wet area. After the final coat, allow approximately 30 minutes of curing at 22°C before molding. When spraying, maintain a suitable distance from the mold and ensure thorough ventilation.
Store unopened containers in a dry location, ideally between 8°C and 21°C, and keep the container tightly closed because the material is moisture-sensitive and flammable.
