Abstract
A suspension of finally divided hardened aminoplast or phenoplast resin, particularly melamine-formaldehyde resin, is prepared by mixing an aqueous solution of the resin or its precursors with a water-insoluble stabilizing agent, particularly microcrystalline cellulose; sufficient water is provided to exceed the water tolerance level of the resin and thus form a uniform emulsion or suspension of resin particles in water. Cure of the resin is then advanced such as by heating to form partially or fully cured resin particles of relatively uniform particle size.
