residual moisture

Residual moisture refers to the amount of water that remains in a material after it has been dried. This can be important for many materials such as wood, concrete or plaster.

Too much residual moisture can cause the material to change shape, shrink or crack. In some cases, it can even lead to mould or rot.

The residual moisture of bonded parts also plays an important role in adhesive bonding technology. This can lead to a reduction or loss of the joining quality or, in the case of moisture-curing adhesives, to accelerated curing. It is always important to know how the adhesive used reacts to the residual moisture of the material to be joined in order to achieve the most ideal joining conditions.

In extreme cases, a change in the residual moisture content of the parts to be joined after joining can even cause the adhesive layer to peel off. (E.g. drying out of wood bonding).
