FIELD: chemistry.
SUBSTANCE: invention relates to a stable adhesive composition containing a urea-free diluent and non-denatured soya flour mixed with water, wherein urea-free diluent is added in amount from 0.1 to 70 % of dry weight by total weight of adhesive; said diluent is selected from a group consisting of glycerol, ethylene glycol, propylene glycol, neopentyl glycol and polymeric combinations thereof, pH is less than 5.0; and urea is not added to composition. Optionally composition can also include adding a cross-linking agent, additional diluent or both components to adhesive based on non-denatured soya flour and urea-free diluent, and/or addition of emulsion or polymer dispersion.
EFFECT: composition is characterised by improved stability of viscosity, excellent high strength in wet or dry state, more efficient method of producing and low cost.
