Mold Release Agents are essential for ensuring smooth production, consistent surface quality, and extended mold life. Correct application is just as important as choosing the right product. Below we explain practical steps and considerations when using mold release agents such as Shin-Etsu KS-707 and km-742t.

Surface Preparation

Before applying any release agent, the mold surface must be properly prepared:

• Clean thoroughly: Remove dust, old residues, and contaminants that may affect adhesion.

• Dry completely: Ensure the mold is moisture-free, as trapped water can interfere with the release layer.

Proper preparation sets the foundation for an even coating and reliable deMolding performance.

Application Techniques

Different application methods can be selected depending on the production environment:

• Spraying: A fine mist provides uniform coverage and is suitable for large or complex molds.

• Brushing or wiping: Ideal for detailed molds or smaller surfaces where precision is required.

• Dilution control: For agents like KS-707, manufacturers may dilute according to specific process needs to achieve optimal release balance.

Usage in Sensitive Formulations

When working with skincare-related additives or cosmetic compounds, KS-707 offers controlled release while maintaining product purity. Apply a thin layer evenly, avoiding excess that could transfer to finished products. This ensures compliance with strict safety and performance standards.

Usage in Industrial Production

For large-scale manufacturing, KM-742T demonstrates excellent performance under high temperatures and repetitive molding cycles. Reapplication should be scheduled at intervals that match production demands—typically after several cycles—rather than after every single use. This increases efficiency while maintaining release performance.

Maintenance and Reapplication

Over time, residues may accumulate on the mold surface. Regular inspection is recommended:

• Monitor coating thickness to avoid buildup.

• Reapply when demolding resistance increases.

• Use appropriate cleaning solutions compatible with silicone-based release agents before re-coating.

Conclusion

Using a mold release agent effectively requires more than just application—it involves preparation, correct technique, and ongoing maintenance. KS-707 is designed for delicate and additive-sensitive applications, while KM-742T excels in industrial-scale, high-temperature processes. By applying them correctly, manufacturers achieve smoother production, reduced downtime, and longer mold life.
