The optimal amount of the filler adsorbent has been found, in which the properties of the prepared adhe-sives meet process requirements. The experiments revealed that the chosen filler can perform the function of the hardener adhesive that eliminates the traditional formulation of the chlorine-containing component. To increase the viability of the prepared adhesive composition to 8-12 hours it was suggested to add to the composition of the adhesive 20 % solution of ammonia water.
