FREKOTE 44NC | Krayden

Main features

Multi-Cycle Mold Release
Reduced Mold-Surface Contamination Risk
Non-Silicone Downstream-Compatible Formulation

Product Description

LOCTITE® FREKOTE® 44NC is a non-silicone, dry-film mold-release coating designed for semiconductor transfer, compression, and injection molds. It provides consistent release, protects mold surfaces from contamination, and minimizes flash or sticking for high-volume production.

Key features

Consistent release: Supports multiple cycles without reapplication under documented mold conditions.
Protective coating: Preserves mold surface integrity and reduces contamination risk.
Non-silicone formulation: Compatible with post-mold processing and downstream packaging.

Processing Summary

Application involves spraying or brushing onto clean mold surfaces, followed by brief flash-off before molding cycle start. Multiple thin coats may be applied for extended release performance.

Preparation: Ensure mold surface is free of cured resin or debris; wipe or clean prior to application.

Application: Spray or brush uniformly; allow to flash off. Avoid puddling or thick layering.

Post-application: Inspect for uniform film. Reapply thin layers for extended cycles as required by production.

Release Performance

Multiple molding cycles

Maintains release under recommended mold temperatures

Temperature Range

Up to 175°C

Supports typical semiconductor molding temperatures

Residue

Minimal

Reduces risk of package contamination

Technical Guidance

Issue: Flashing or sticking

Ensure mold is clean, apply thin uniform coat, allow proper flash-off before molding cycle.

Issue: Reduced release after multiple cycles

Reapply a thin layer of FREKOTE® 44NC as per recommended production intervals.
