FIELD: chemistry.
SUBSTANCE: adhesive contains a basic component in form of brewer's or distiller's yeast which is a waste from the brewing or distillation industry. The residue of brewer's or distiller's yeast is treated with 2% sodium hydroxide solution in ratio of 1:1. The adhesive composition contains the treated residue of brewer's yeast, glycerin and boric acid. Components of the composition are in the following ratio, pts. wt: residue of brewer's or distiller's yeast treated with 2% sodium hydroxide solution in ratio of 1:1 96.0-98.0; glycerin 1.9-3.7; boric acid 0.1-0.3.
EFFECT: adhesive composition has high adhesive capacity and low cost.
