To fulfill the D2 criterion the bonded wood substrates must have higher tensile shear strength than 8 MPa after been immersed in water for 3 h and dried for a week according to conditioning method B. All wood substrates bonded with the xanthan gum dispersion and all except one wood substrate bonded with the 6 wt% tamarind gum from Premcem dispersion delaminated in water. All wood substrates bonded with locust bean gum dispersion fulfill the D2 criterion. The specimens bonded with locust bean gum dispersed in brown liquor do also fulfill the D2 criterion, but the tensile shear strength is lower than the water dispersion of locust bean gum. The wood substrates bonded with the other gum dispersions have lower tensile shear strength and does not fulfill the D2 limit. Cascol barely fulfills the D2 criterion and the standard deviation is large.
