4. Conclusions
Locust bean gum, guar gum, xanthan gum and tamarind gum have successfully been dispersed and evaluated as wood adhesives. Even though the molar mass of the gums is very high, it was possible to prepare dispersions. However, the viscosity of the dispersions is very high and therefore only dispersions with a low dry solids content could be prepared. The contact angles against water for the films are higher and more stable than the corresponding results for Cascol. The film prepared of locust bean gum dispersed in brown liquor shows lower contact angles and a poor water resistance.
