A substrate for use in an aqueous slurry has a polymeric coating to provide a compliant and sticky surface. The polymer coating has a chemical to render the surface hydrophobic so as to attract hydrophobic or hydrophobized mineral particles in the slurry. The substrate can take the form of a conveyor belt, a bead, a mesh, an impeller, a filter or a flat surface. The substrate can also be an open-cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers and/or additives; hydrophobizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica, and/or fumed hydrophobic silica; MQ resin; and/or other additives to control and modify the properties of the polymer.

Polymer coating for selective separation of hydrophobic particles in aqueous slurry

A process of coating an open-cell foam substrate includes the steps of arranging two rollers separated by a gap; positioning the substrate above the gap; providing a coating material onto the substrate, feeding the substrate through the gap so as to achieve a layer of the coating material on the substrate, wherein the coating material is selected from the group consisting of a polysiloxane derivative, acrylic polymer, butyl rubber, natural rubber, nitriles, styrene block copolymers with ethylene, styrene block copolymers with propylene, styrene block copolymers with isoprene and polyvinyl ether and modifying the coating with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers; hexamethyldisilazane; and silica.

Processes for coating reticulated foams

Compounds according to formula (I) wherein Z is S, SO, or SO, may be prepared by a process that includes charging to a reactor hydrogen sulfide and an alkyl glycidyl ether according to formula (III), in the presence of a base.  The compounds may also be prepared by contacting an alkoxychlorohydrin according to formula (II) with a sulfide source.
