摘要

Process for the preparation of an adhesive for dentures, characterized in that in a first process step 100% polyvinyl acetate with 50% alcohol (96%) are mixed at a temperature of 80 ° C until a liquid solution is formed, in a second process step 100% Ester of Rosin (Valrosin) is dissolved or liquefied with 80% coconut oil at a temperature of 100 ° C, so that after cooling this mixture, a pasty mass is formed, in a third step in 100% alcohol (96%) 2% hydroxypropylcellulose (Klucel) are stirred in a fourth step in 100% of the cooled mixture of the first step, 20% of the cooled mixture of the second step are stirred, and in a final step of the entire mass of the fourth step 4% hydroxypropyl cellulose (Klucel) are added. The addition of hydroxypropylcellulose not only makes the adhesive smoother, but it also greatly simplifies the cleaning of dentures.
