Abstract
Aminoplast or phenoplast moulding compositions are manufactured by passing an aqueous solution of a urea-formaldehyde resin, of an optionally phenol-modified melamine-formaldehyde resin or of a phenol-formaldehyde resin into a fluidized bed drier, by spraying the resin onto fillers and drying it. The compositions are used for crockery, household articles and technical components for the electrical industry.
