  • Patent number: 9073083
    Abstract: Aqueous compositions useful as pretreatments prior to painting and to reduce the formation of rust in the uncoated condition consist essentially of water, an organo-functional silane, a compound of a Group IV-B element, and optionally a polyvinyl alcohol, stabilizing agents, wetting agents, thickeners, and biocides, and have an alkaline pH>7. A process for treating a metal surface includes contacting the surface with such an aqueous composition. The compositions and processes were found to have further benefits in comparison to the zinc phosphate metal pretreatment thought to be the standard in the industry. Preferably, the pH of the compositions is alkaline, which has been found to improve the efficacy of a silane as a surface treatment to improve uniformity of paint adhesion. By operating in the alkaline pH range, it was found that flash rusting and/or blush rust were significantly reduced.

    Abstract: A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; colouring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for colouring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the coloured surface. The colouring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.

  • Publication number: 20120269973
    Abstract: The present invention comprises an automated apparatus capable of spray depositing polyelectrolytes via the LbL mechanism with minimal or no human interaction. In certain embodiments, the apparatus sprays atomized polyelectrolytes onto a vertically oriented substrate. To counteract the effects of irregular spray patterns, the substrate is preferably slowly rotated about a central axis. In certain embodiments, the apparatus also includes a forced pathway for the droplets, such as a pathway created by using a vacuum. In this way, a thicker or three-dimensional substrate can be coated. In certain embodiments, the apparatus is designed so as to be scalable. Thus, through the use of multiple instantiations of the apparatus, a large or irregularly shaped substrate can be coated. Rolls of textile can therefore be coated using the apparatus. Additionally, the present invention includes a method to uniformly coat a substrate, such as a hydrophobic textile material, using aqueous solutions of polyelectrolytes.

  • Publication number: 20120255898
    Abstract: A polyamide membrane comprising reaction product of an anhydrous solution comprising an anhydrous solvent, at least one polyfunctional secondary amine and a pre-polymer deposition catalyst; and an anhydrous, organic solvent solution comprising a polyfunctional aromatic amine-reactive reactant comprising one ring. A composite semipermeable membrane comprising the polyamide membrane on a porous support. A method of making a composite semipermeable membrane by coating a porous support with an anhydrous solution comprising an anhydrous solvent, a polyfunctional secondary amine and a pre-polymer deposition catalyst, to form an activated pre-polymer layer on the porous support and contacting the activated pre-polymer layer with an anhydrous, organic solvent solution comprising a polyfunctional amine-reactive reactant to interfacially condense the amine-reactive reactant with the polyfunctional secondary amine, thereby forming a cross-linked, interfacial polyamide layer on the porous support.
