Product Description

H.B. Fuller MP-55310 Methacrylate Structural Adhesive provides a two-part methyl methacrylate system for structural bonding of metals, thermosets, thermoplastics, and composite assemblies. The resin and activator mix 1:1 by volume or weight and provide a 7-9 minute open time with fixture in 19-23 minutes at 25 deg C. The adhesive fills gaps up to 0.125 in and reaches full cure in 24 hours. Typical cured data include Shore D 75 hardness, 4,350-5,800 psi tensile strength, and overlap shear of 3,300 psi on carbon steel and 3,100 psi on aluminum under ASTM D1002 conditions.

Key features

  • Seven-to-nine-minute open time: Provides a defined working window for adhesive placement and assembly.
  • Nineteen-to-twenty-three-minute fixture: Develops fixture strength in 19-23 minutes at 25 deg C.
  • One-eighth-inch gap fill: Fills bond gaps up to 0.125 in in bonded assemblies.

Applications / Suitable for

  • Bonding aluminum, steel, stainless steel, and e-coated metals
  • Bonding fiberglass, phenolic, gel coat, epoxy, and polyurethane materials
  • Bonding ABS, polycarbonate, nylon/PA, PVC, PEEK, and PBT or PET blends
