Solvay METLBOND® 2550 Film Adhesive
Categories: Polymer; Adhesive; Thermoset; Bismaleimide (BMI)

Material Notes: Metlbond 2550 is a 350°F (177°C) cure, 440° (227°C) post-cure, modified BMI film adhesive with good high-temperature adhesive properties for bonding composites, metals and sandwich structures.

Features & Benefits:

  • Service temperature of -67 to 450°F (-55 to 232°C) dry / 375°F (191°C) wet
  • Six-fold toughness increase over first generation BMI adhesives
  • Outstanding bond strength with composites and metals
  • Controlled flow for sandwich structural bonding
  • Epoxy-like processing with 21+ days shop life at 75°F (24°C)
  • No volatiles evolved during cure
  • Co-cures with Cytec’s BMI composite systems
  • Reticulation capability with unsupported variant
Applications:
  • Honeycomb sandwich bonding
  • Metal-to-metal bonding
  • Metal-to-composite bonding
  • Composite-to-composite bonding
