B8X-480 is a high-performance, rubber-toughened instant adhesive engineered for structural bonds that must withstand shock, vibration, and moisture. Its distinctive black color provides visual contrast for quality control, while its enhanced flexibility significantly improves resistance to crack propagation—making it the preferred choice for automotive, industrial machinery, and electromechanical assemblies where failure is not an option.
Unlike standard cyanoacrylates, B8X-480 maintains integrity under dynamic loading and offers reliable adhesion even on slightly damp metal surfaces.

Performance Highlights
- Highest Shear Strength in Series: 3,800 psi—ideal for load-bearing joints.
- Exceptional Peel & Impact Resistance: Rubber-toughened formulation absorbs energy and resists delamination.
- Superior Moisture Tolerance: Bonds reliably in humid conditions; excellent long-term durability on metals exposed to condensation or splashes.
- Versatile Substrate Bonding: Proven on steel, aluminum, neodymium magnets, EPDM, nitrile rubber, and engineering plastics.
- Black Color for Traceability: Enables easy visual inspection of bond lines in automated or manual assembly.
Typical Applications
- Electric Motors & Sensors: Bonding magnets to steel housings or rotors
- Automotive: Mounting rubber bushings, brackets, and trim in under-hood or chassis applications
- Industrial Equipment: Securing wear pads, dampers, and metal-rubber composite parts
- Power Tools: Handle-to-housing assembly requiring drop and vibration resistance
- Marine & Outdoor Gear: Metal components exposed to humidity or intermittent water contact
Application Guidelines
- Surfaces should be clean and free of oil; light abrasion improves durability on passive metals (e.g., stainless steel).
- Slight surface moisture is tolerated, but standing water must be avoided.
- The 90-second fixture time allows for precise alignment in complex assemblies.
- Store upright in a cool, dry place (<25°C); keep nozzle sealed to prevent premature curing.
