Application Area
Surface Application

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.

Recommended surface preparation for optimal adhesion is as follows:

  • PC, ABS, Glass: IPA wipe
  • Nylon: Plasma treatment
Application Instructions
  • Place adhesive film between substrates
  • Cure Activation Conditions
    • Temperature: 75°C - 110°C
    • Activation Time: 30s - 90s at temperature
    • Pressure: 10 - 25 N/cm²
  • We recommend uniform pressure distribution for optimal bonding. Use the contour plot on the right as a guild to determine the optimum bonding conditions for your process.
  • The glued materials can be further processed immediately after bonding and cooling down (handling, trimming, cutting, etc.)
  • Optional step: EM9002 adhesive film may be pretacked to a substrate prior to processing. To pre-tack EM9002 to a material, use the processing guide lines below:
    • Bond Line Temperature: 45 - 50°C
    • Pressure: 5 - 20 N/cm²

Flexel™ EM9002 - Application Instructions

Note: The chart above shows typical peel strength (N/25 mm width) when bonding polycarbonate coupons to nylon fabric with Flexel™ EM9002-50. This is 180° degree peel data, pulled at 300 mm/min. After the parts were bonded, they were allowed to condition at 23°C and 50% relative humidity for about 24 hours.
