Excellent material compatibility
Low-solvent formula means it can be used on virtually all common building surfaces, e.g. also on Styrodur.
When used with the elastic EPDM films, building movements are optimally compensated.
Good adhesive properties
Even adheres to slightly damp (but not wet) surfaces.
Compound does not run off masonry.
Acid, isocyanate and silicone-free
EPDM sealing tape adhesive, Flexband adhesive and Flexband adhesive Plus must not come into contact in wet conditions. Do not use EPDM sealing tape adhesive on surfaces that have been pre-treated with butyl and bitumen primer. We recommend performing preliminary tests on bitumen strips due to the large number of different systems.
EPDM sealing tape adhesive is not suitable for use on and in aquariums, for bonding on vapour barrier, vapour retarders and roof lining membranes, and also on substrates from PMMA, PP, PE, PTFE (Teflon®) and on substrates treated with release agents.
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!
For bonding Würth EPDM sealing tapes to window and door reveals and to other construction surfaces. Can also be used on uneven reveal surfaces.
Suitable surfaces are concrete, sand-lime brick, brick, plaster, natural stone, aluminium, steel, zinc, copper, glass, wood, MDF, tiles, ceramics, plasticiser-free PVC, Styrodur foam and also for bonding components made of these materials to each other.
The substrate must be tested for compatibility with the adhesive. The substrates must be solid, load-bearing, clean, dry and free from grease, oil and dust. Remove any release agent that may be present. If necessary, prime with bond and seal primer for metal (art. no. 089010061) or bond and seal primer for plastic/wood/stone (art. no. 089010062).
Some applications require a primer, e.g. with heavy mechanical load or above-average load with water after hardening.
Apply the EPDM sealing tape adhesive to the surface and wipe off with a toothed spatula. Depending on the film width on the structure, the adhesive width should be at least 40 mm, and on the element at least 30 mm with a thickness of 1 mm in each case. Pay attention to the planning specifications if a full-surface bond is required. With film overlaps, maintain an overlap length of at least 10 cm.
Glue the EPDM tape to the surface and press on lightly using a press-on roller (art. no. 0693011750), while ensuring tension-free and kink-free installation. Once the film has been pressed on, the adhesive joint must have a layer thickness of at least 1 mm and be completely filled with adhesive without any air pockets. The tape can be adjusted up to 30 minutes after bonding. Use up open containers as quickly as possible. During application and curing, avoid contact with alcohol, hydrocarbons, cleaning agents and solvents.
