SealPot SP4011 is a one-part translucent potting gel. It is a flowable, addition-curing, silicone that cures at elevated temperature to a very firm rubbery gel with excellent adhesion to various plastics and metals. It is non-corrosive and selfpriming adhesion, and can be automated to dispense from pails or hand extruded from cartridge.
- Special Features & Benefits
- Very soft for stress compliance
- Excellent dielectric properties
- Mechanical shock and vibration damping
- Low bleeding, low volatile
- Broad range of temperature stability
Applications & Uses

For the non-sag (thixotropic) version of this potting gel, please select the United Adhesives’ product SealPot SP4018. For room temperature cure RTV silicone potting rubber, please select United Adhesives’ product SealPot SP4510.
- Processing Instruction
- Important! SealPot SP4011 is platinum cure system. Please keep applied surface / housing clean and avoid using this material on any place that contains sulfur, amine, phosphorous, organo-metals, acid, etc. because these contaminants could inhibit the cure the material. Please let the compound thoroughly thaw after taking it out from freezer. This typically needs half to one hour depending on the size of container.
- We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to United Adhesives Inc.

Safety & Health
- Safety
SealPot SP4011 silicone contains neither toxic nor corrosive substances that might require special handling precautions. General hygiene regulations should be observed.
Storage & Handling
- Shelf Life
- 3 months at 5°C (Viscosity double)
- Storage
SealPot SP4011 has a shelf life of at least 3 months when stored at < 5°C freezer in the originally sealed container. Storage beyond the date specified does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
