FIELD: chemistry.
SUBSTANCE: method involves applying a synthetic adhesive onto the surfaces to be glued. The adhesive contains urea formaldehyde resin and maleic acid as an acidic hardener. The surfaces to be glued are joined until complete solidification. The acidic hardener is used in amount of 0.5-2.0% of the weight of the urea formaldehyde resin.
EFFECT: use of maleic acid as a hardener for gluing wood materials improves strength characteristics of glued joints.
