  • Amphiphilic Silver Delivery of Bactericidal Activity in Coatings (#3001.1) Expand dropdown

    This invention provides a method to manufacture a bactericidal composition utilizing a silver ion surfactant and a coating composition binder that can be easily incorporated into a number of finishing systems. A finishing system so enhanced can confer biocidal properties in coatings such as paint, urethanes or other protective coatings. It could also be incorporated into fiber and textile products.

    Applications could include coatings for surfaces in medical facilities, food processing facilities, ventilation ducts, telephones, public transportation and reception areas.

  • Anionic Surfactants Lethal to Gram Positive Bacteria (#3009.1) Expand dropdown

    We have discovered a class of anionic surfactants that are lethal to Gram positive bacteria, and as such promise to be effective as additives in antibacterial coatings in paints and related consumer, hospital, and industrial interior and exterior coating formulations. These anionic surfactants also promise to be effective as local and systemic agents for the treatment of various diseases caused by Gram positive bacteria, such as staphylococcal infections, streptococcal infections, bacterial pneumonia, and Bacillus anthracis infections.

    These invention surfactants are advantageous over the few known anionic surfactants, such as sodium dodecylsulfate, known to be active against Gram positive bacteria, because the surfactants of the present invention hydrolyze much more easily and are more easily eliminated from the body.

  • Creating Antimicrobial Fabric Using Sol-gel/N-halamine Chemistry (#3024.1) Expand dropdown
    Method for imparting antimicrobial properties to nylon/cotton blend fabric. Nylon/Cotton blend fabric samples were tested for antimicrobial efficacy using AATCC 147 test method against Staphylococcus aureus (a Gram positive) organism and Escherichia Coli, Gram negative organism and also AATCC 100 method using Staphylococcus (Gram positive) and Pseudomonas aeruginosa (Gram negative) organisms after washing the fabric several times with soap and water at 60o C. The treated fabrics exhibited effective biocidal activities against both the Gram positive as well as negative organisms and maintained all textile properties as well.
  • Self-stratifying Automotive Top Coat Composition and Process (#3012.1) Expand dropdown
    The application of multiple layers of coating is costly and presents technical challenges such as prolonged application time and the like. Our technology streamlines the process of manufacturing a coating by combining at least one multifunctional layer such as the basecoat and clearcoat into one single layer. Further, the novel coating composition preserves the current attributes and characteristics such as providing enhanced adhesion, durability, UV light screening, higher gloss and an overall simplified and rapid application.
  • Controlling Pigment Location in Self-stratifying Coatings (#3012.2) Expand dropdown
    In producing pigmented coating compositions, particularly in multi-layered (e.g., self-stratifying or self-layering) compositions, it is uncertain whether the pigment dispersion may segregate in a particular layer or be found throughout the coating. In certain applications, it may be desirable to produce a pigmented top or intermediate film layer within a composite paint. Our technology controls the location of pigments within self-stratifying or self-layering coating compositions.
  • Chromate-free Organic-inorganic Hybrid Pretreatment for Corrosion Resistance of Aluminum Alloys (#3010.4) Expand dropdown

    This invention describes development of a novel technology of materials and application, for chromate-free pretreatment of aluminum and aluminum alloys, for their protection from environmental corrosion.

    Chemical pretreatment of such alloys is extremely important of protection of overall coating system. Hexavalent chromate based pretreatments are by far the best performing pretreatments known to this industry. Due to environmental and toxicity issues associated with use of chromate based materials, the recent changes in regulations (EPA) does not allow use of such materials. Therefore, there is an acute need for chromate-free pretreatments which has comparable or better performance than. Many such technologies have been commercially available in recent days, but their performance is far inferior to chromate-based ones.

  • Aqueous Polyurethane/Polyurethane-urea Dispersions (PUD) with High Bio-based Content (#3027.2) Expand dropdown

    Polyurethane dispersions (PUDs) have emerged as very important class of binders for coatings due to their versatility, performance and low VOC. The conventional commercial PUDs are almost exclusively derived from petrochemical resources accounting for their high carbon foot-print, besides increasingly high cost. Bio-based materials are emerging as very important alternative resources for sustainable development of coatings.

    A novel polyol with customized features has been derived from soybean oil (soy-polyol) by a single-step low energy intensive process. Polyurethane dispersions based on this soy-polyol, with bio-based content of up to ~60% have been prepared using conventional prepolymer process. Films of PUDs have been characterized for physical and mechanical properties. Besides high bio-based content, the ease of processing, versatility, and excellent performance properties of these novel PUDs provide useful insight into their potential commercial applications as environmentally- friendly and sustainable binders for coatings.

    This invention can be used to provide a nanoporous to microporous material of three- dimensional structure by a single pot synthesis where the porosity can be tuned chemically and the pores can be filled with diverse phases for advanced materials applications.

    Applications include filters to decontaminate and recycle water which incorporate both leaching and non-leaching pharmacophores that will kill problematic bacteria. The technology can also be used as supports for catalysts as well as scaffolds for cell and tissue regeneration and culturing.

    The invention is a composition of matter in which polymer latexes with conventionally sized particles are blended with polymer latexes with nanoparticle sized particles. A sub-set of the invention is coatings based on these blends. The combination of particle sizes improves the overall performance of the latex. Another aspect of the invention is an improved process for making nanoparticle latexes.

Accordingly, applications include concrete flooring, counter tops, bridge restoration, road restoration, long-life enhancer for roads, floors, bridges.
  • Nanoparticle Dispersions with Ionic Liquid-based Stabilizers (# 3021.1) Expand dropdown
    We report the direct preparation of SWCNT nanolatex dispersions by mixing and joint ultrasonication, resulting in well dispersed systems with SWCNT concentrations of about 0.5% by weight. This is essentially competitive with the most concentrated aqueous suspensions reported and 5-100 fold more concentrated than most of the surfactant and polymer stabilization and dispersion studies in water previously reported. Applications, in view of the adhesion to polypropylene and ABS, as well as to metals and cellulose-based substrates, include thermally absorbing coatings for light activated sealing, antistatic discharge layers, ink jet writable conductive layers and RFID devices, and a general solution to making plastic components more amenable to electrospray and electrodeposition coating operations. This last application area should greatly increase the range of plastic materials than can be substituted for metals in vehicle design and manufacture.
