wood adhesive has to wet and flow satisfactorily over the wood surface, and also penetrate the surface to some extent. A high dry solids content is often desired since a smaller amount of adhesive is required to obtain adhesive properties while at the same time less water has to be removed in the bonding stage (Frihart, 2005). However, a high dry solids content will bring about a high viscosity which counteracts spreading of the adhesive. The reference adhesive, Cascol, has a lower viscosity compared to the prepared dispersions and is easily applied on a wood surface since it wets and flows over the surface. The locust bean gum dispersion has the highest viscosity of 330 Pa s followed by guar gum, 280 Pa s. These adhesives are quite difficult to spread evenly on the substrate, possibly due to water being strongly associated to the polysaccharides, or aggregation of polysaccharide molecules. The guar gum dispersion also has a tendency to form lumps during application. The xanthan gum dispersion is also rather difficult to spread but this appears to be due to poor wetting of the surface. All dispersions prepared with tamarind gum are easily applied on the surface, similar to Cascol. They wet and flow over the wood surface. Locust bean gum dispersed in brown liquor is a thick dispersion that tends to dry very fast during the application, not allowing for appropriate film formation.
