Patent ID: 8586666

Claim:
A method for producing a coagulated adhesive comprising the steps of: (a) providing an aqueous adhesive dispersion of a chlorinated polyolefin and an additive, which aqueous adhesive dispersion has a pH range from above 10 to 13; (b) introducing CO 2 gas to the aqueous adhesive dispersion and homogenizing the introduced CO 2 gas in the aqueous adhesive dispersion; (c) measuring the pH of the aqueous adhesive dispersion continuously during the CO 2 introduction; (d) stopping the introduction of CO 2 gas to the aqueous adhesive dispersion when the pH reaches 9.0 or below; whereby the aqueous adhesive dispersion coagulates; and wherein the steps (b) to (d) are conducted in a time period of from 0.5 to 20 minutes.
