240 Max. Gap Fill & Flow Control Plastic Bonding Cyanoacrylate Adhesive, Clear

Physical Properties of Uncured Adhesive

• Chemical composition: Ethyl cyanoacrylate
• Appearance: Colourless
• Viscosity @ 25°C: 1,200-2,500 mPa.s (cP)
• Specific gravity: 1.1

Typical Curing Properties

• Maximum gap fill: 0.4mm 0.017 in
• Fixture/handling time* (0.3 N/mm² shear strength is achieved)
  
  • 15-20 seconds (Steel)
  • 15-20 seconds (Buna N Rubber)
  • 15-20 seconds (Phenolic)
• Full strength: 24 hours

*Handling times can be affected by temperature, humidity, and specific surfaces being bonded. Larger gaps or acidic surfaces will also reduce cure speed but this can be overcome by the use of Permabond C Surface Activator (CSA) or Permabond QFS 16.

Typical Performance of Cured Adhesive

• Shear strength* (ISO4587)
  
  • Steel 21-25 N/mm² (3000-3600psi)
  • Aluminium 8-9 N/mm² (1200-1300psi)
  • Zinc 10 N/mm² (1450psi)
  • ABS >8 N/mm² (1200psi) SF**
  • PVC >11 N/mm² (1600psi) SF**
  • PC >5 N/mm² (700psi) SF**
  • Phenolic 14N/mm² (2000psi)
• Impact strength (ASTM D-950): 3-5 kJ/m² (1.4-2.4 ft-lb/in²)
• Dielectric constant @10kHz: 2.5
• Dielectric strength: 25 kV/mm
• Coefficient of thermal expansion: 90 x 10^-6mm/mm/°C
• Coefficient of thermal conductivity: 0.1 W/(m.K)
• Hardness (ISO868): 85 Shore D

*Strength results will vary depending on the level of surface preparation and gap.
