Abstract
The invention relates to a method for preparing a high dry substance Stein Hall adhesive, comprising the steps of preparing a carrier portion by gelatinising at least a part of the total starch in the adhesive in an alkaline medium, diluting the carrier portion with a volume of water, and adding the remaining secundary starch in which a first step said carrier portion is prepared, in a second step the carrier portion is diluted with a volume of water, followed by the addition of at least a portion of the secundary starch, and in a third step the remaining alkali is added in a diluted form together with the secundary starch. The addition of the remaining secundary starch and alkali is preferably performed stepwise.
