J-B Weld Pro-Series Quick Setting Steel Reinforced Epoxy (#52076) is a two-part, steel-reinforced adhesive that forms a permanent, machinable bond on metal and multiple surfaces. It sets in 5–7 minutes at room temperature and reaches full cure in as little as 6 hours, delivering a tensile strength of 3,127 PSI.

J-B Weld Pro-Series #52076 is a professional-grade, steel-reinforced epoxy designed for general-purpose bonding and repair. Mixed at a 1:1 ratio from a 9.4 fl oz cartridge, it forms a hard, dark-gray paste bond that can be shaped, tapped, filed, sanded, and drilled once fully cured — making it a versatile solution for permanent structural repairs.

J-B Weld Pro-Series Quick Setting Reinforced Epoxy bonds to a wide range of materials, including:

  • Metal (steel, iron, aluminum, and more)
  • Ceramic
  • Concrete
  • Fiberglass
  • Stone

  • Working Time: Approximately 6 minutes
  • Functional Cure: 6 minutes (enough to hold parts in place)
  • Full Cure Time: 6 hours (maximum)
  • Overnight Bond: Sets to a hard bond overnight for full structural integrity

. Once fully cured, J-B Weld Pro-Series #52076 can be shaped, tapped, filed, sanded, and drilled. This machinability makes it particularly useful for structural repairs where the bonded area needs to be finished or fitted precisely — a key advantage over standard adhesives.
