FIELD: chemistry.
SUBSTANCE: adhesive composition contains a polyfunctional isocyanate, polyether polyol and a catalyst. The catalyst consists of at least one organic compound of iron and at least one chelating ligand. The multicomponent adhesive composition is prepared in form of at least two inter-reacting chemical components. One of the at least two inter-reacting chemical components contains a polyfunctional isocyanate and a catalyst, and the other contains polyether polyol. The multicomponent adhesive composition is used to produce articles from bound lignocellulose composite based on a lignocellulose substrate, especially for making oriented fibre panels.
EFFECT: invention enables to obtain articles using filler with high moisture content, which are structured at low pressing temperatures without reducing efficiency of the press.
