BondSeal BS8350 is a high bonding strength adhesive. It is a non-slump (thixotropic), additioncuring, one component silicone that cures at elevated temperature to a very tough rubber with excellent bonding strength to various plastics and substrates. It is non-corrosive and self-priming adhesion, and can be automated to dispense from needle or hand extruded from cartridge.
- Special Features & Benefits
- One part for easy applying
- Very strong bonding to various substrates
- Non-slump, non-sag (thixotropic)
- Low bleeding, low volatile
- Low thermal stress

- For flowable version of this adhesive, please select the United Adhesives’ product BondSeal BS8360.
- For thermally conductive bonding adhesives, please select the United Adhesives’ products ThermoBond 3519 or ThermoBond 3821.
- Processing Instruction
- Important! BondSeal BS8350 is platinum cure system. Please keep applied surface clean and avoid using this material on any surface that contains sulfur, amine, phosphorous, organo-metals, acid, etc. because these contaminants could inhibit the cure the material.
- 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.

Storage & Handling
- Shelf Life
- Minimum 3 months at 4°C (Viscosity double)
- Storage
BondSeal BS8350 has a shelf life of at least 3 months when stored at ~4°C 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.
