  • Publication number: 20230060079
    Abstract: A surface modifying coating for an article that includes a first component having a surface in frictional engagement with a surface of a second component. At least a portion of a surface of one of the components is coated with a coating including a mixture of at least two silicones: (i) a hydrolyzable organopolysiloxane with a viscosity of less than or equal to 1,000 centistokes and that is capable of crosslinking reaction upon exposure to moisture at ambient temperature; and (ii) a second organopolysiloxane copolymerizable with the first hydrolyzable organopolysiloxane and having viscosity of greater than or equal to 5,000 centistoke; wherein the coating provides a maximum break loose force equal to or less than three times a kinetic extrusion force such that stiction is reduced between engaged surfaces.

  • Patent number: 7857285
    Abstract: An elastomeric gland is provided for a luer activating device (LAD). and comprises a unique lubricant and/or wetting agent and/or anti-clotting agent incorporated into the elastomer gland during raw material formulation, calendar blending/molding/curing to deliver the surface lubricity and/or wettability and/or avoid slit plane re-knitting and/or gland induced valve stick down of such devices Functional additive chemistries are selected in terms of generated functional performance level, thermal stability against processing, molecular migratability, molecular weight and elastomer substrate of interest. These additives could include lubricants like chemically modified silicone oils and/or wetting agents like silicone-based surfactant. Elastomer gland with wetting agent would ease fluid path priming and minimize micro air bubble adherence to gland surface.

  • Patent number: 7521588
    Abstract: A polymeric web exhibiting a soft and silky tactile impression on at least one side thereof is disclosed. The silky feeling side of the web exhibits a pattern of discrete hair-like fibrils, each of the hair-like fibrils being a protruded extension of the web surface and having a side wall defining an open proximal portion and a closed distal portion. The hair-like fibrils exhibit a maximum lateral cross-sectional diameter of between 2 and 5 mils, and an aspect ratio from 1 to 3. Methods and apparatus for making the polymeric web utilize a three-dimensional forming structure having a plurality of protrusions being generally columnar forms having an average aspect ratio of at least about 1.
