Abstract

In a first aspect, the invention relates to a method for producing microcapsules filled with liquid isocyanate. In particular, the method according to the invention is a method for microencapsulating liquid isocyanate with polyol and/or polyamine. The invention further relates to correspondingly obtained microcapsules and to adhesive systems comprising said microcapsules. Said adhesive systems are inter alia used in methods for adhering two connecting sections, in particular for adhering wood in a bonded manner. Finally, the invention relates to corresponding workpieces made of adhered wood or wood with other materials, such as metal or plastic.
