Permabond 820 Instant CA Adhesive Fast Set Temperature Resistant Low Viscosity Thin General Purpose

Applications

Permabond 820 is widely used as a cyanoacrylate adhesive for:

• High-speed industrial assembly and production lines
• Bonding rubber, metals, and engineered plastics
• Applications requiring rapid fixture times
• Electronics and components exposed to heat (e.g., wave soldering)
• Precision bonding of small or tight-fitting parts
• Situations requiring a fast set adhesive with minimal application steps

Features

• High-performance instant CA adhesive with rapid bonding capability
• Low viscosity CA glue for excellent capillary action and tight joint penetration
• Thin CA adhesive ideal for precision applications
• Strong adhesion to metals, plastics, and rubber substrates
• 100% reactive, solvent-free formulation
• No mixing or heat curing required
• Designed for high-speed manufacturing and assembly environments
• Maintains bond performance under elevated temperatures

Performance

Permabond 820 is engineered for consistent, high-strength performance across demanding thermal and mechanical conditions:

• Fixture Time: 10–15 seconds (steel, Buna N rubber, phenolic)
• Full Cure: 24 hours to maximum strength
• Shear Strength (ISO 4587 on Steel): 19–23 N/mm² (2800–3300 psi)
• Viscosity: 100 mPa.s (cP) – low viscosity CA glue
• Maximum Gap Fill: 0.15 mm (0.006 in)
• Hardness: 85 Shore D

Thermal Performance

• Maximum Temperature Resistance: Up to 200°C (392°F) for short-term exposure (when joint is not heavily stressed)
• Operating Temperature Range: -55°C (-65°F) to elevated temperatures depending on bonded materials
• Thermal Conductivity: 0.1 W/(m·K)

This instant adhesive provides a reliable balance of speed, strength, and temperature resistance, making it a dependable solution for demanding industrial bonding applications.
