Specialized coating applied to molds to facilitate easy release of silicone seal rings during manufacturing.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Coverage | 20–40 m²/L | Depends on mold surface porosity and application thickness; higher for polished molds. |
| Dry Time | 5–30 min | At 20–25 °C and 50% RH; forced air drying reduces time. |
| pH Range | 6.0–8.5 pH | For water-based formulations; outside this range may cause emulsion instability. |
| Shelf Life | 6–12 months | In unopened original container at 5–35 °C; avoid freezing. |
| VOC Content | 0–250 g/L | Water-based formulations typically <50 g/L; solvent-based up to 250 g/L.EPA Method 24 |
| Application Method | Spray, brush, or wipe | Spray recommended for complex geometries; brush for localized application. |
| Operating Temperature | 150–250 °C | Continuous; short peaks up to 300 °C for silicone curing cycles. |
| Coefficient of Friction | 0.05–0.15 dimensionless | Measured on cured film; lower values indicate better release.ASTM D1894 |
| Film Thickness | 1–5 µm | Dry film thickness; thicker films may cause dimensional issues on seals. |
| Chemical Resistance | Resistant to silicone rubber, sulfur, and peroxides | No degradation after 100 cycles at 200 °C. |
| Mold surface temperature | 150–250 °C | Outside this window: Below 150 °C: incomplete curing, poor adhesion; above 250 °C: thermal degradation, loss of release properties. |
| Mold pressure | 10–50 MPa | Outside this window: Below 10 MPa: incomplete transfer; above 50 MPa: coating squeeze-out, reduced life. |
| Relative humidity during application | 30–70% RH | Outside this window: Above 70% RH: water absorption, film defects; below 30% RH: static issues, uneven coverage. |
| Curing time per cycle | 5–20 min | Outside this window: Shorter than 5 min: incomplete release; longer than 20 min: coating degradation, sticking. |

Manufacturer profiles associated with Mold Release Coating.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Typically every 1-5 cycles depending on coating type, mold temperature, and silicone formulation. High-temperature applications may require more frequent reapplication.
Yes, improper coating can cause surface defects, dimensional inaccuracies, or contamination. Proper selection and application are critical for maintaining product quality.
Yes, water-based and solvent-free formulations are available that meet environmental regulations while maintaining effective release properties.
