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

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Electrical Properties
Arc Resistance
ASTM-D495 expresses arc resistance as the number of seconds that a material resists forming a surface-conducting path when exposed to a high-voltage, low-current arc occurring intermittently. Results obtained from a nominal 3 mm thickness are meant to represent the material’s reaction in any thickness.
126 s
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
17 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
