FIELD: chemistry.
SUBSTANCE: adhesive composition comprises urea-formaldehyde resin obtained from 53-57 wt h the urea-formaldehyde resin powder and 47-43 wt h water, ammonium chloride and active shungite sorbent mixture of wood flour with the following component ratio, wt h: urea resin - 90-95; ammonium chloride - 0.5-1.0; active mixture of wood flour and shungite sorbent - the rest.
EFFECT: invention reduces the free formaldehyde content, reduce the amount of the main components, to increase bonding strength, and also reduce the curing time of the adhesive composition and, consequently, improve productivity.
