<p>The invention pertains to adhesive compositions comprising water glass, at least one low molecular weight dextrin, and at least one pH controlling agent, and not containing a mono-, di- and/or trisaccharide, and is characterized in that the dextrin is a low molecular weight dextrin with an Ostwald viscosity of less than 45 mPa.s when measured as a solution in water at 25 DEG C and a concentration of 355 g/kg and that the pH of the adhesive is between 10 and 13. Such compositions demonstrate not only a high curing rate and a good wet tack, but also an excellent storage stability. The compositions are useful as a glue or sizing agent. When they are used as a glue, improved crush values of the finished products are observed.</p> |
