Description
High-Performance Hybrid Adhesive
Würth Bond + Seal Power is a high-strength, elastic structural adhesive based on hybrid polymer technology. Designed for dynamic load-bearing applications, it provides strong adhesion on a wide range of substrates, delivering reliable performance in both industrial and construction environments.
Versatile and Durable Bonding
The adhesive demonstrates excellent adhesion to metals, plastics, composites, wood, ceramics, and concrete, making it suitable for multi-material assemblies. Its elastic yet low-stretch formulation absorbs vibration and movement without compromising joint integrity.
UV and Weather Resistance
Thanks to its UV stability and non-corrosive nature, Bond + Seal Power is ideal for visible joints in outdoor and exposed conditions. It protects metal substrates from corrosion, even under challenging environmental influences.
Paintability and Finish Compatibility
The adhesive can be painted over both before and after skin formation using standard commercial paints (except alkyd resin paints). Two-component epoxy paints are compatible. Due to the difference in elasticity between paint films and the adhesive, slight cracking of the paint at the joint may occur.
Food-Safe Cerification
With NSF P1 registration (136996), Bond + Seal Power is internationally approved for use in food processing and storage areas, making it suitable for hygienic sealing and bonding tasks.
Notice:
- Additional adhesive layers may be applied within skin formation time.
- Avoid contact with alkyd resin paints.
- Perform preliminary paint compatibility tests before coating.
