Mold Release & Anti-Stick Agents

Injection molding, casting and composite manufacturing need silicone and non-silicone release agents
Updated Jun 2026
Solution Approach

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.
Recommended Chemistries (6)
Food-Grade Silicone Antifoam Emulsion (10-50% Active)
CAS 63148-62-9
Silicone Fluids & Oils
Defoaming / Foam Control
High-viscosity PDMS lays down a continuous low-surface-energy film between part and tool so the molding releases cleanly

Hexamethyldisiloxane (HMDSO)
CAS 107-46-0
Silicone Fluids & Oils
Conditioning
Volatile silicone carrier that deposits a thin release film then flashes off, leaving minimal transfer to the part
Melting Point: -66 °C   Boiling Point: 99 °C   Density: 0.7638 at 20 °C

Octamethyltrisiloxane (MDM)
CAS 107-51-7
Genuine fit. MDM is the L3 member of the linear volatile methylsiloxane (VMS) series, sitting directly between the already-listed MM (L2, hexamethyldisiloxane) and MD2M (L4, decamethyltetrasiloxane). Same family, same mechanism: low-viscosity volatile siloxane that deposits a thin PDMS release film then evaporates clean with no transfer to molded parts. This is exactly the release chemistry the pa
