FIELD: chemistry.
SUBSTANCE: invention relates to an adhesive system comprising (a) component-resin containing melamine-urea-formaldehyde resin in which amount of melamine, expressed in form of M/(M+U) varies from 30 to 60 wt%, and molar ratio F/NH2 varies from 0.6 to 0.79, and (b) a curing component containing at least one acid, acid-forming salt or acid salt and does not contain or contains less than 15 wt% urea. Invention also relates to its application, method of producing wood-based article and articles obtained using said method.
EFFECT: technical result is providing an adhesive system containing melamine-urea-formaldehyde resin with low or zero level of release of formaldehyde, but is effective as an adhesive for wood without need to spend very considerable time on pressing or application of high temperature.
