Title: VISCOSITY-STABLE DEXTRIN COMPOSITION IN THE COATING OF PAPER AND/OR CARDBOARD
Abstract:
The present invention relates to a dextrin composition having a molecular weight distribution expressed as the following weight percentages: more than 0.5% of molecules having a molecular weight of less than 103 daltons, between 35% and 45% of molecules having a molecular weight of between 103 and 2.5x104 daltons, between 35% and 50% of molecules having a molecular weight of between 2.5x104 and 5x105 daltons and between 5% and 20% of molecules having a molecular weight of greater than 5x105 daltons. The invention also relates to the composition for surface treatment or coating of paper or cardboard comprising such a dextrin composition, and the process for producing such a surface treatment and/or coating composition. The invention lastly relates to the process for coating a paper or a cardboard by the application of a coating or surface treatment composition according to the invention and to the paper and/or cardboard thus obtained.
