B8X-402 is a next-generation instant adhesive formulated for mission-critical bonding in high-temperature environments. Combining ultra-fast fixture speed with extended thermal endurance (up to 135°C), it delivers consistent, durable performance on both standard and challenging substrates—including low-surface-energy plastics and elastomers that typically resist conventional adhesives.
Designed for engineers and manufacturers who demand reliability under stress, B8X-402 bridges the gap between speed, strength, and environmental resilience.

Performance Highlights
- Extended High-Temperature Resistance: Stable continuous service up to 135°C—ideal for under-hood, power electronics, and near-engine applications.
- Superior Adhesion to Difficult Substrates: Bonds reliably to rubber, TPE, EPDM, nylon, ABS, and other low-energy or chemically inert materials.
- Rapid Processing: Achieves handling strength in as little as 3 seconds, supporting high-throughput assembly lines.
- Consistent Mechanical Integrity: Maintains >90% of bond strength after thermal cycling and long-term exposure to elevated temperatures.
- Low Viscosity for Precision: Excellent flow into micro-gaps ensures uniform coverage without excess squeeze-out.
Typical Applications
- Automotive: Sensor mounting, gasket retention, trim bonding in high-heat zones
- Electronics: Bonding components near heat sources (e.g., power modules, LED drivers)
- Industrial Equipment: Assembly of fluid handling parts, pneumatic fittings, and wear-resistant components
- Aerospace & Defense: Interior fixtures requiring thermal stability and vibration resistance
- Maintenance & Repair: Fast, permanent fixes in environments where standard adhesives degrade
Application Guidelines
- Surfaces must be clean, dry, and free of contaminants. Light abrasion or solvent wipe recommended for optimal results.
- For polyolefins (PP, PE) or silicone-based rubbers, use a surface activator/primer to maximize bond strength.
- Apply in a well-ventilated area; avoid prolonged skin contact.
- Store unopened containers at <25°C in a dry environment to preserve reactivity and shelf life.
