  • Patent number: 10836890
    Abstract: This invention discloses a transparent standalone resin or masterbatch concentrate composition and manufacturing method of transforming commercial transparent grade base thermoplastics into anti-biofouling resins through extrusion or any similar hot melt mixing processes. The re-compound solids enable a number of product reforming processes, including but not limited to thermoforming, profile extrusion, injection molding, blow molding, blow filming, film casting, and spinning into articles of different shapes and geometries or overmolding on plastic substrates that can resist surface adsorption of microbes, mammalian cells, proteins, peptides, nucleic acids, steroids and other cellular constituents after solidification. The articles formed thereof additionally exhibit mechanical reinforcement and no leaching while retain the optical clarity of the base thermoplastics in the same product form as quantified in terms of the light transmittance and haze.

    Abstract: The present invention relates to self-cleaning surfaces having improved mechanical stability and a process for the production thereof. The present invention is achieved by producing self-cleaning, hydrophobic, structured surfaces having mixtures of particles, which are fixed on their surface and which comprise structure-producing particles selected from semimetal or metal oxides, silicas and metal powders, and wax particles. Structured surfaces that are structured by such mixtures of particles are distinguished by substantially higher mechanical stability of the structure and are therefore especially suitable for the production of self-cleaning surfaces, which are exposed to relatively high mechanical loads, such as, for example, the surfaces of tarpaulins, awnings, greenhouse elements, conservatories or truck tarpaulins.

  • Patent number: 7704561
    Abstract: This invention is directed to methods of treating inorganic surfaces with aqueous compositions including ionic organosilicon compounds. Surprisingly, it has been found that the application of water soluble ionic organosilicon compounds, which until the present invention have only been used in small quantities to solubilize silanes, to inorganic surfaces provides the treated surface with an excellent hydrophobic property. The present invention exclusively utilizes ionic organosilicon compounds as the main or sole component for imparting water repellency upon surface treatment of inorganic substrates. The methods of the present invention comprise the application of ionic organosilicon compounds to inorganic surfaces whereby imparting water resistance to the substrate. After application, a treated surface may be characterized as having a long term water repellant property.
