  • US3962491A Process for producing resin-coated sand

    A process for producing resin-coated sand particles for use in shell moles wherein a phenolformaldehyde resin in an initial stage of condensation is sprayed into a hot zone to form droplets which gravitationally descend to a cold zone and solidify. The particles are mixed with sand, heated to a temperature above the melting point of the resin and coat the sand.Resin Coated Sand Resin Coated Sand Manufacturer Resin,Resin coated sand is an excellent and accurate method in foundry practices. For producing a casting of high precise dimensions, smooth surface, free of blow holes & to avoid casting defects you must use shell molding process & therefore Resin Coated Sand.
