will. Melamine-phenol or resorcinol resins have proven to be particularly suitable on their own or in a mixture with urea resins.
It has also been shown that the following mixing ratio of the mass to be molded allows easy processing and gives the moldings particularly good properties:

The components are mixed for about 20-40 minutes in a rapid mixer and the mixture obtained in this way is subjected to shaping. The molded products are optionally dried.
PATENT CLAIMS:
1. Process for the production of molded bodies, in particular plates, pipes, dowels and the like. Like., which consist of base material and organic binders, by casting, spraying, rolling or pressing using lignite material as the base material, characterized in that the base or filler fiber lignite with a fiber length of predominantly over 1 mm, optionally mixed with change known basic resp. Fillers, is used.
