摘要： The invention relates to a method for producing an adhesive layer, wherein a chlorinated polyolefin comprises an aqueous adhesive dispersion and further additives having a pH from 10 to 13 being provided, said adhesive is adjusted to a pH below 9.0 by introducing CO
2 , then an adhesive layer is applied, characterized in that the quantity of CO
2 to be introduced is determined and controlled by measuring the pH value of the dispersion.

摘要： The invention relates to a method for gluing two substrates together, wherein one substrate is coated with a layer of an aqueous adhesive containing dispersions from chlorinated polyolefins and additives having a pH of 10 to 13. An activator solution is applied to the first or second substrate in a subsequent step, wherein the activator solution contains substances comprising acid groups, and gluing the coated surfaces together using light pressure. The invention describes a 2-part adhesive consisting of a storage-stable aqueous adhesive dispersion containing 25 to 50% by weight chlorinated polyolefins, 5 to 30% by weight additional polymers, and additives and water having a pH value of 9 to 13 and an activator solution as a second component, wherein the activator solution contains carboxylic acids, sulfonic acids, phosphonic acids, polymers comprising carboxylic acid or sulfonic acid groups, inorganic acid salts or Lewis acids, and water or organic solvents.
