SIKAFORCE 7550L15 BLACK IN 450 ML CARTRIDGE

SIKAFORCE 7550L15 BLACK - CARTRIDGE 450 ML

SikaForce 7550 L15 is an elastic, fast-curing and non-sagging assembly adhesive.

• 
  
• 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
  

• 
  
• 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
