SIKAFORCE 7550L15 BLACK - CARTRIDGE 450 ML
SikaForce 7550 L15 is an elastic, fast-curing and non-sagging assembly adhesive.
Characteristics
- Cold applied and highly thixotropic
- Short cut-off string
- Fast cure and strength development independent to air humidity
- Elastic/good gap-filling capabilities
- Adequate working time to complete assembly, despite rapid cure
- Bonds well to a wide variety of substrates
- Withstands high dynamic stresses
- Vibration damping
- Electrically non-conductive
- Ageing resistant
- Solvent- and PVC-free
Application
- Suitable for structural joints that will be subjected to dynamic stresses, where rapid strength development and fast cure is an essential requirement
- Ideal for the adhesive bonding of large components and assemblies
- Suitable substrates are plastics and metals, particularly aluminium sheets, steel, metal primers and paint coatings (2-component systems), wood and ceramic materials
