Description
GP-7200 is a mercapto functional methylalkyl (paintable) silicone polymer. GP-7200 is designed to provide good release of molded metal, plastic and rubber parts, with the mercaptoalkyl functionality providing both enhanced release performance and greater heat stability to the release film. GP-7200 is compatible with most organic coatings and adhesives, allowing subsequent coating of molded parts without unusual surface preparation. The structure of GP-7200 is as follows:
The following list summarizes some of the special features of GP-7200:
- Ease of Cleaning
- Good Lubrication
- Good High Temperature Stability
- Reactive with Sulfur & Peroxide Cured Elastomers

Processing and Safety Guidelines
GP-7200 has been formulated to provide good compatibility with organic coatings and adhesives. Nonetheless, surfaces contaminated with GP-7200 should be cleaned properly before painting or bonding - as is true even with conventional petroleum oil contaminants. GP-7200 should be handled with the same precautions common to the use of industrial products. May cause eye and skin irritation. For additional precautions, refer to Material Safety Data Sheet.
Packaging/Handling/Storage
GP-7200 is supplied in 5-gallon (40 lbs.) pails and 55-gallon (440 lbs.) drums. No special storage is required.
