Application Uses

Mitre Bond Superglue B400 is a high-strength, fast-acting adhesive primarily used in woodworking and carpentry but also suitable for various other applications. Here are ten possible uses for it:

Woodworking and Carpentry

Ideal for bonding wooden mitre joints quickly and securely, such as in picture frames, furniture making, and moulding.


Applicable in various crafting projects, especially where quick setting and a strong bond are needed, like in model making or DIY decorations.

Repairing Ceramics

Can be used to fix broken ceramics or pottery, providing a strong bond that sets quickly.

Plastic Repairs

Suitable for bonding plastic components, such as in small appliances or toys, as long as the plastics are not polyethene or polypropylene.

Jewelry Making

It can adhere to small jewellery-making parts, including attaching stones or metal components.

Musical Instrument Repair

Useful for small repairs on musical instruments, such as reattaching parts of wooden instruments like guitars or violins.

Leather and Fabric Bonding

It can be used in leatherwork or for bonding heavy fabrics, though testing on a small area is recommended to ensure compatibility.

Automotive Applications

Handy for minor automotive repairs, like reattaching loose trims or fixing broken plastic parts in car interiors.

Home Repairs

It can be used for home repair tasks, such as fixing broken household items made from plastic, wood or metal. It isn’t recommended for use on glass as any initial bond is likely to deteriorate.

Produces a strong ultimate bond

Mitre Bond Superglue B400 is a one-component, solvent-free system and does not require the use of a catalyst, heat or clamps. When a thin layer of Mitre Bond is applied between two surfaces it comes into contact with atmospheric moisture and a rapid polymerization occurs producing the ultimate bond.

Directions for Use

  1. Make sure the surfaces to be bonded are clean and dry (preferable to solvent-wipe plastics, glass, and rubber, and to acid-treat metals).
  2. Dispense a drop or drops to one surface only. Apply only enough to leave a thin film after compression.
  3. Press parts together and hold firmly for a few seconds. Good contact is essential. An adequate bond develops in less than one minute. (Maximum strength is achieved in 24 to 48 hours).
  4. Wipe off excess adhesive from the top of the container and recap B400 if left uncapped, may deteriorate by contamination from moisture in the air.
  5. Because B400 polymerises on contact with moisture surfaces, sometimes whitening will occur on the surface of the container or the bonded materials. Should this happen, wipe surfaces well with debonder.
