Product Description
MOLYKOTE® 7 Release Compound is a white, translucent dimethyl silicone compound used for release, lubrication, sealing, and surface-protection applications involving plastics, rubber, metals, and adhesives. Its polydimethylsiloxane fluid and inert amorphous silica formulation maintains a serviceable consistency from -40 to 204°C (-40 to 400°F), while providing moisture resistance, electrical insulation, and low volatility. The non-curing compound can be applied by hand, brushing, wiping, or suitable automated equipment and is used in molding, rubber processing, cable installation, extrusion, and packaging equipment.
Key features
- Broad service temperature range: Maintains a serviceable consistency from -40 to 204°C (-40 to 400°F).
- Release and lubrication performance: Provides release, sealing, and rubber-lubrication properties for plastics, rubber, metals, and adhesive-contacting equipment.
- Stable non-curing silicone compound: Resists moisture and oxidation, is practically nonvolatile, and shows little tendency to dry out during service.
Applications / Suitable for
- Mold release for foundry shell and core molds
- Break-in treatment for tire-press bladders
- Rubber lubrication and preservation
- Release applications involving adhesives and glues
- Cable pulling of rubber-covered cable through conduit
- Plastic extrusion and plastic-film packaging equipment
