Technical Specifications

General Properties
Adhesive Thickness
Adhesive Thickness
Adhesive thickness indicates the thickness of an adhesive layer.

It refers to the adhesive thickness of a single side so for double sided tapes it always needs to be multiplied.
 25 µm
Work life @25°C
Work life @25°C
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.

It is based on the change in viscosity and it can rely on the application requirements.
 60 hours
Thermal Properties
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
 82-306 °C
Coefficient of Thermal Expansion (CTE)
Coefficient of Thermal Expansion (CTE), α1
Coefficient of Thermal Expansion (CTE), α1
CTE α1 (alpha 1) is the slope of the Coefficient of thermal expansion in a temperature range below the Glass transition temperature (Tg).

It explains how much a material will expand until it reaches Tg.
 36 ppm/°C
Coefficient of Thermal Expansion (CTE), α2
Coefficient of Thermal Expansion (CTE), α2
CTE α2 (alpha 2) is the slope of the Coefficient of thermal expansion in a temperature range above the Glass transition temperature (Tg).

It explains the extent to which a material will expand after it passes Tg.

Directions for Use

  1. Ensure all surfaces to be bonded are free from surface contamination.
  2. Adhesive must be completely used within the product's recommended work life.
  3. Remove the tape reel from the moisture-resistant package and load into the tape application machine.
  4. Store unused adhesive film in the original sealed moisture-resistant package until needed.
