Bostik 7008 adhesive combines the advantages of tape with the characteristics of a reactive system.

Immediately after installation, the component exhibits a high initial bond strength (high internal bonding force) due to the formation of a highly flexible powder state with excellent resistance to sagging. The reaction begins with atmospheric moisture, resulting in a non-reversible curing adhesive.

The initial bond strength, coupled with high tackiness, makes the product suitable for applications where parts need to be moved immediately after production.

Bostik 7008 adheres well without the need for a primer on glass surfaces and does not require immediate UV curing when the adhesive contacts the glass, as it is UV protected by a ceramic coating.

  • The product is solvent-free and does not contain isocyanate compounds or PVC.
  • Excellent UV resistance and anti-aging properties.
  • Good adhesion on various surfaces without the need for a primer.
  • Maintains elasticity within a temperature range from -40°C to 120°C.
  • Neutral and odorless curing.
  • Low volume expansion.
  • Low electrical conductivity.


Bostik 7008 adhesive is easily dispensed using a hand gun or pressure gun at temperatures ranging from +5°C to 35°C. The application speed can be increased by heating up to a maximum of 70°C.

For optimal adhesion, the surface needs to be clean, dry, and free of oil before use. Wipe the ceramic coating as well as various surfaces such as aluminum, coated steel, and polyester (GRP) with Simson Cleaner I.

In cases of high temperature resistance, exposure to significant mechanical stress, especially in wet conditions, when a large amount of adhesive is required, it is recommended to use Simson Prep M. Prep M cleans and prepares the surface simultaneously. For more detailed information about Prep M, refer to the product’s technical documentation.

After a few minutes of processing, the glass panel can be installed. The glass panel must be installed within 15 minutes after using Bostik 7008 AP. If there is no ceramic coating or the ceramic coating does not provide sufficient UV protection, Simson Prep G should be used after the glass panel has been cleaned with Cleaner 14 or Cleaner 1, unless there is a protective layer on the glass-adhesive contact surface against UV radiation. Excess ISR 70-08AP adhesive that has not dried can be cleaned or removed with a clean, colorless, lint-free cloth moistened with Liquid 1. It is advisable to conduct a preliminary test to assess the impact of these cleaning solutions on the bonding surface.


Bostik 7008 adhesive can be stored for 12 months in its original unopened packaging in a dry place at temperatures between +5°C and +30°C (for adhesive cartridges, the storage period is 18 months).
