Abstract

The present invention relates to a process for the preparation of mixtures of isocyanate and water which are stable for a short time for glueing particulate material, in particular chips, fibers, or the like, in which isocyanate is injected at high pressure into the water characterized in that the water is delivered to the site of injection as a stream under low pressure, and to an apparatus for carrying out such process.
