Important notice and disclaimer

Specifications are subject to change without notice. Please contact us for the latest version. Our data is based on experience in the laboratory and in practice. The user is recommended doing their own tests for intended application under practical conditions. Due to different materials, application methods and local given facts on which we do not have influence, we cannot give any warranty. We recommend that users carry out their own tests to confirm the suitability of the product for their particular application.

Directions for Use

1) Substrates to be bonded should be clean and free from moisture, dirt, oil and other contaminants. Megasorber AC5 Adhesive Cleaner is recommended for surface cleaning.

2) Hold spray gun at a consistent distance of 150mm to 250mm from the substrates producing a web pattern across the substrates with minimal overlap.

3) The adhesive should be applied at a coating weight of 2 dry grams per sq.m (dry), or 80% to 100% coverage.

4) When applying Megasorber A100 to porous materials, it is recommended applying two coats. Apply the first coat and allow to dry. This will act as a sealer. When dry, apply the second coat and allow to dry properly before bonding. This helps to ensure that the adhesive does not soak-in to substrate and that you have the proper amount on the surface to achieve a strong, permanent bond.

5) Allow the adhesive to dry properly before bonding. To check for dryness use the back of your fingers and press into the adhesive and lift up. Any adhesive transfer or legging indicates that the adhesive requires more time to dry. If the adhesive feels tacky, but there is no transfer or legging, the adhesive is ready for bonding. If there are heavy areas of adhesive present, press the back of your fingers in the adhesive and twist. If a skin has formed, this will tear it open and allow you to notice that the adhesive requires more dry time. Do Not use the palm of your hand to check for dryness. Dry time can vary depending on temperature, humidity and coating weight.

6) Bonds can be made as soon as the adhesive is dry.

7) Position the pieces carefully, since the strong bond is made instantly upon contact.

8) Use good uniform pressure to ensure good film fusion. A roller is the optimum method for applying pressure. Use the maximum pressure possible without damaging the substrate.

Special Precautions

For optimum results store canister above 18°C during use, but must always be above 10°C. Allow substrates to acclimatise to normal room temperature (18°C) for 48 hours before bonding. Do not exceed open time of the adhesive. Keep canister off cold concrete floors during use. If adhesive is expelled wet or as a jet, canister is too cold – move to warm environment and allow to thoroughly acclimatise before reusing.


  • Use only in well ventilated areas.
  • Do Not thin or reactivate with solvents.
  • Do Not incinerate.
  • Do Not expose to extreme heat over 50°C.
  • Keep away from sources of ignition.
  • Release pressure before disconnecting hose.
  • Test for suitability before use.
