Abstract: Described is a process of producing a lignocellulosic composite or a product thereof, wherein the process comprises at least the steps of making a formed sheet by preparing a mixture comprising lignocellulosic particle and a heat-curable binder composition comprising as components for hardening the binder via reaction with each other at least one, two or more carbohydrate compounds and one or two compounds having two or more amino groups, comprising hexamethylenediamine and/or polylysine, and forming a sheet from said mixture, so that the formed sheet results, and of at least temporarily simultaneously compacting and dielectrically heating the formed sheet in a dielectric heating and pressing unit, so that the heat-curable binder composition hardens and the lignocellulosic composite results. Furthermore described is a lignocellulosic composite, which is preparable according to that process, a construction product comprising such lignocellulosic composite and the use of such lignocellulosic composite as a building element in a construction product.
