ISEGA:
Can be used in food-related areas, e.g. for bonding components made of plastic and metals in areas where food is processed or stored. Components manufactured with the adhesive may be used in direct contact with food, as far as the adhesive is concerned, as long as it has hardened sufficiently. Clearance certificate no.: 46630 U18
- Not suitable for permanent use in highly concentrated acids and bases or aggressive organic solutions, such as toluene, ketones and esters.
- PMMA must only be glued when it is not under tension; otherwise, stress cracks are likely to occur
- Protect from frost.

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee the consistent quality of our products. We reserve the right to make technical changes and further develop products. Please observe the technical data sheet!
This adhesive is especially recommended for applications exposed to high dynamic, thermal or climatic loads. Thanks to its flexibility, it can also be used to bond materials with different thermal expansion coefficients. Ideal for automotive components, electrical components, household appliances, metal manufacturing, plastic tanks, plastic and composite manufacturing, signs and displays, thermoform housings, applications in the pharmaceutical, beverage and food industries in compliance with ISEGA certificate; when cured, it is also safe for the bonded components to come into direct contact with food.
The substrates must be clean, dry, and grease-free. Attach the static mixing tube to the opened adhesive cartridge and insert the cartridge into the respective dosing gun.
Discard the first 2 cm of mixed adhesive.
Apply sufficient adhesive to the surfaces to be bonded, ensuring that there is a minimum gap of 1mm when subsequently pressing the parts. Pressing time is approx. 10 min.
