Core Gum

Core Gum

• Description:

  • Paste-like adhesive, typically white or grayish-white in color.
  • May have a mild chemical odor.

• Uses:

  • Used in core joining and mold joining applications in high-temperature environments.
  • Acts as a bonding agent to hold together core materials (e.g., wood, metal) used in casting or molding processes.
  • Provides temporary adhesion until the permanent bonding material cures.

• Chemical Composition:

  • Primarily silicate-based, often containing:
    • Sodium silicate (Na2SiO3) – main binding component.
    • Fillers and thickeners (specific ingredients may vary).

• Physical Properties:

  • Pasty consistency, allowing for good adhesion between surfaces.
  • Sets and dries upon air exposure, forming a strong bond.
  • Heat resistant, able to withstand high temperatures encountered in casting or molding processes (specific temperature resistance depends on the product formulation).

• Safety Information:

  • Mild irritant to skin and eyes.
  • Wear gloves, eye protection, and long sleeves when handling core gum.
  • Avoid prolonged or repeated contact with skin.
  • Inhaling dust or mists can irritate the respiratory system.
  • Ensure proper ventilation in the workspace.
  • Keep out of reach of children and pets.
