1. Product Overview

  • Technology: Cyanoacrylate
  • Chemical Type: Ethyl cyanoacrylate
  • Appearance (uncured): Clear to slightly cloudy gel
  • Components: One-part, no mixing required
  • Viscosity: High, thixotropic
  • Cure Mechanism: Humidity-cured
  • Application: Bonding
  • Key Substrates: Metals, Plastics, and Elastomers
  • NSF Certification: Registered under NSF Category P1 for non-food contact use in food processing areas

2. Applications

  • Designed for bonding difficult-to-bond materials with uniform stress distribution and high tension/shear strength
  • Suitable for metals, plastics, elastomers, and porous materials like wood, paper, leather, and fabric
  • Gel consistency prevents adhesive flow on vertical surfaces

3. Typical Properties

Uncured Properties

Property Value
Specific Gravity (25°C) 1.1
Casson Viscosity (25°C) 150 to 450 mPa·s
Brookfield Viscosity (25°C) 18,000 to 40,000 mPa·s (20 rpm), 100,000 to 300,000 mPa·s (2.5 rpm)

Cured Properties (After 30s to 72h at 22°C)

Property Substrate Strength (N/mm²) Strength (psi)
Tensile Strength Buna-N 6.0 – 15.1 870 – 2,190
Lap Shear Strength Steel (grit blasted) 20.9 3,030
Lap Shear Strength Aluminum (etched) 17.1 2,480

Cure Performance

  • Fixture time varies by substrate: Steel (30-60s), Aluminum (2-10s), Neoprene (10-15s), ABS (<5s), Wood (30-60s for oak, <5s for balsa)
  • Cure rate depends on bond gap, humidity (optimal 40-60% RH at 22°C), and activator use
