Choosing adhesives for on-site bonding

TRADA image

Moisture content, temperature, humidity and surface preparation are key to the quality of a bond. Adhesive products to be used on site need specific properties that are different from adhesives commonly used in factories, for the following reasons:

- The quality of wood surfaces is not easy to control on site.

- Bonding pressures and controlled temperatures are not easy to achieve on site.

- Factory-produced bonded assemblies usually have bond line thicknesses of 0.5mm or lower, whereas the bond line thicknesses found in on-site bonding may be 1mm or even as high as 12mm.
