101 Wicking Grade Plastic Bonding Cyanoacrylate Adhesive, Clear

Physical Properties of Uncured Adhesive

• Chemical composition: Ethyl cyanoacrylate
• Appearance: Colourless
• Viscosity @ 25°C: 2-3 mPa.s (cP)
• Specific gravity: 1.1

Typical Curing Properties

• Maximum gap fill: 0.05mm (0.002")
• Fixture/handling time* (0.3 N/mm² shear strength is achieved)
  
  • 3-5 seconds (Steel)
  • 2-5 seconds (Buna N Rubber)
  • 5-10 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 19-23 N/mm² (2800-3300 psi)
  • Aluminium 7-9 N/mm² (1000-1300 psi)
  • Zinc 8-10 N/mm² (1200-1500 psi)
  • ABS >6 N/mm² (900psi) SF**
  • PVC >6 N/mm² (900psi) SF**
  • PC 6 N/mm² (900 psi)
  • Phenolic 12-14 N/mm² (1700-2000 psi)
• 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.
