Applications & Uses

Application Area
Surface Preparation

Surfaces must be clean and free from dust, fatty substances and release agents. For optimum adhesion, the surface tension of the substrates to be bonded should be more than 38 dynes/cm.

Application Instructions
  • Place adhesive film between substrates.
  • Cure Activation Conditions
    • Temperature: 90°C - 110°C Activation
    • Time: 60s - 90s at temperature
    • Pressure: 20 - 25 N/cm²
    • We recommend uniform pressure distribution for optimal bonding
  • The glued materials can be further processed immediately after bonding and cooling down (handling, trimming, cutting, etc.).
  • Optional step: FN2100 adhesive film may be pre-tacked to a substrate prior to processing. To pre-tack FN2100 to a material, use the processing guide lines below:
    • Bond Line Temperature: 45 - 50°C
    • Pressure: 5 - 20 N/cm²

Technical Details & Test Data

Typical Shear Strength

Flexel™ FN2100 - Typical Shear Strength

Note: Pulled at crosshead speed of 30 mm/min. Shear area is 25 mm x 12 mm. Samples were pressed for 60 seconds at bond line temperature of 90°C and pressure of 22N/cm². Shear samples were conditioned for 24 hours at 50 % RH and 23°C before testing.

Typical Peel Strength

Flexel™ FN2100 - Typical Peel Strength

Note: Peeled at crosshead speed of 300 mm/min. Samples were pressed for 60 seconds at bond line temperature of 90°C and pressure of 22N/cm². Peel samples were conditioned for 24 hours at 50 % RH and 23°C before testing.
