GP-967 is an endcapper for the synthesis of aminopropyl-terminated silicone fluids and for the production of silicone-epoxy and silicone polyimide copolymers especially useful in electronics applications. A unique manufacturing process insures that GP-967 has only gamma - aminopropyl substitution and none of the beta isomer. This is expected to give better reactivity in copolymer synthesis and improved heat stability.

Processing and Safety Guidelines

GP-967 is an alkaline material due to its amine reactive groups. Care should be exercised in handling GP-967 to prevent contact with skin and eyes. Wear safety glasses with side shields and rubber gloves when handling. Consult Safety Data Sheet for additional details.


GP-967 is supplied in 5-gallon (35.2 lbs.) pails and 55-gallon (385 lbs.) drums. Moisture sensitive. Keep container tightly sealed. Store below 100°F. Do not weld or cut drums, even when empty.
