Abstract:
Use a centrifuge, especially a peeler centrifuge, that has a coarse salt particle layer deposited on its screen to effect recovery of an epoxy resin, especially a liquid epoxy resin, from a product slurry, which epoxy resin has a lower residual salt content than an epoxy resin recovered without use of the coarse salt particle layer.
