Technical Details & Test Data

Use Limitations

Molykote® 7 Release Compound should not be applied to any surface that will be painted or finished. Such coatings may not adhere to the silicone-treated surfaces. If contaminated by a silicone coating, parts can be wiped or washed with solvent or washed with detergent. To O-rings or other components made from silicone rubber because they can deteriorate the silicone rubber. This compound will also slightly swell natural butyl rubbers. Any rubber should be tested for excessive swell or shrinkage.

Because each application may vary in chemical composition, pressure, flow velocity, relubrication requirements and equipment design, the silicone compound should be tested before adopting for regular use.

This compound is not intended for use with liquid oxygen or other strong oxidizing chemicals and should not be used in applications requiring LOX compatibility.

This product is neither tested nor represented as suitable for medical or pharmaceutical uses.
