All wood substrates delaminate when soaked in water for 4 days according to conditioning method C, except the specimens bonded with locust bean gum. All wood substrates bonded with locust bean gum held together after the treatment. However, none of the bonded wood substrates fulfill the D3 criterion of 2 MPa. The fact that all wood substrates held together after the treatment show the potential of locust bean gum with good bonding performance as well as water resistance.
