Patents Assigned to Resource Development L.L.C.
  • Patent number: 8735618
    Abstract: Non-flammable, VOC-free organosilane quaternary ammonium compositions are provided in the form of pure or substantially pure water-soluble products that have bactericidal, fungicidal and viricidal activity and which are capable of bonding to various surfaces to form durable hydrophobic coatings. The resulting compositions are free of unreacted chloropropyltrialkoxysilanes, alkylamines and organic solvents that would otherwise provide flammable, corrosive, and/or toxic properties thereby inhibiting their safe and effective use in surface care, personal care and coating products.

  • Patent number: 7589054
    Abstract: Storage-stable organosilane quaternary compounds are provided in the form of adducts with urea (clathrates). The urea-organosilane quaternary clathrates enable the shipment, storage and preparation of compositions without hazardous solvents for end-use by manufacturers and consumers. Multifunctional cleansing and coating compositions are prepared employing the clathrates without sacrificing the properties and benefits of the organosilane quats.

  • Patent number: 6676733
    Abstract: Physiologically acceptable and non-corrosive silicone compositions are used for treating surfaces such as glass, porcelain, ceramic, marble, granite, metal, coated metal, plastic, wood, painted wood, cement, leather, textile, cloth, and other hard or soft composite surfaces, to render them water and soil repellent. Volatile organic compound (VOC) free cream, paste, powder and solid compositions are provided by the inclusion of particulate stabilizers in the silicone compositions. Solventless silicone compositions provide numerous advantages with improved water and soil repellency qualities.
