  • Patent number: 10136957
    Abstract: Provided, among other things is a leak-resistant elastomeric barrier comprising: an elastomeric barrier comprising elastomeric polymer, having two sides, and coated on at least a portion of a first side with a highly hydrophobic coating such that the initial contact angle with water is about 130° or more, and that contact angle does not decay by more than about 10% over 40 minutes. In embodiments the highly hydrophobic coating comprises hydrophobic silica particles are disposed on a hydrophobic coating disposed on the first side, for example with a hydrophobic coating comprises that a fluorocarbon compound, a polypropylene wax, a polyethylene wax, or a mixture thereof.

  • Publication number: 20160033418
    Abstract: Provided for example is a combination glove comprising: (a) an top elastomer layer with an inner surface, the top elastomer layer being translucent or transparent; (b) an bottom elastomer layer with an outer surface, the bottom elastomer layer being darker than the top elastomer layer; and (c) a space or seam between the layers, wherein to either the inner-top or the outer-bottom surface has been adhered a hydrophilicity promoting composition of (i) a polyvinyl alcohol or (ii) an alkyl-aryl compound or a siloxane compound having a pendent one to two oxy-polymers, or (iii) a quaternary amine including an alkyl of C8 to C24, wherein the oxy-polymer is (1) a poly-oxyalkylene polymer that is predominantly oxyethylene or (2) a polyvinyl alcohol, wherein the hydrophilicity promoting composition enhances the spreading in the space or seam of any of the hydrophilic or aqueous fluid that breaches the top or bottom elastomer layer.
