Outstanding adhesive strength on a wide range of materials and surfaces
Approved for use with foodstuffs (ISEGA certificate)
- Harmless to humans in its hardened state
- Suitable for bonding and sealing in food processing plants
Highly elastic
- Can be used for joining different materials and materials of the same type
- Compensates different material expansions
- Dampens vibrations and noise
Long skin formation time
- Allows complex components to be bonded and sealed
- Also ideal for large surfaces
- Joint parts can be repositioned
Can be sanded and painted over
Following skin formation, it can be mechanically machined and painted over without surface activation (perform preliminary tests to check paint compatibility).
Non-corrosive
Prevents metal corrosion
Low odour
Silicone free
ISEGA:
Can be used where food is processed or stored, e.g. for bonding wall and floor areas in food processing companies.
Clearance certificate no.: 46567 U 18
- Not suitable for glass groove sealing or adhesive bonding on other transparent materials with risk of UV back reflection.
- Direct exposure to sunlight may result in slight surface yellowing and the development of cracks.
- Not suitable for expansion joints in construction applications.
- PVC-based paints and paints that dry by oxidation (oil and alkyd resin-based paints) are not suitable for painting over the adhesive.
- The use of Würth sealant smoothing agent may cause yellowing.
- Caution: Contact with solvents or solvent residues should be avoided, in particular during processing and the curing phase. This can lead to permanent damage of the Bond + Seal.
- Caution: In the case of high surface moisture, very wide adhesive bead application, and/or cavities/air pockets created, backfill foams in the application, there is a risk of blister formation in the adhesive compound.

- For a range of bonding and sealing tasks
- Suitable for bonding and sealing in food processing plants
- For the permanently elastic sealing of spot weld seams
The surfaces must be clean, dry and free from grease. For pre-treatment, please refer to the optimisation table in the technical data sheet.
Cut off the threaded spout, screw on the nozzle and cut it to the required width. Apply the adhesive using a suitable application gun. We recommend a minimum adhesive layer thickness of 3 mm to harness the benefits of thick-coat bonding.
For more information, please refer to the technical data sheet.
