- Characteristic
BondSeal BS8460 is a high bonding strength adhesive. It is a non-slump (thixotropic), addition-curing, two-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.

- Typical Applications
Seal lids, covers, housings, connectors; Attach PCBs, base plates, components; Encapsulate parts, cavities; Automotive electronics; Semiconductor and Telecommunications; Vibration dampening; Thermal stress coupling; For flowable version of this adhesive, please select the United Adhesives' product BondSeal BS8440.; For thermally conductive bonding adhesives, please select the United Adhesives' products Thermobond 3517 or 3519.
- Processing Instruction
Important! BondSeal BS8460 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.; Only components A and B with the same lot number may be processed together.; 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.
