  • Patent number: 8216682
    Abstract: A moisture curable acrylic formulation is provided inclusive of a majority by weight polyacrylic prepolymer. The prepolymer has an average molecular weight of between 3,000 and 6,000 grams per mole and between 2 and 4 moisture curable functional moieties of isocyanate or silane per prepolymer. A thermoplastic adhesive resin is also included within the formulation. When the prepolymer functional moieties are all silane, the thermoplastic adhesive resin is ethylene vinyl acetate resin. A silane molecule is provided within the formulation as an adhesion promoter and also affords a degree of storage stability through sacrificial reaction with water during storage. The resultant formulation achieves a shear strength of at least 10 pounds per square inch when applied to a thickness of 0.75 millimeters between a glass substrate and a vinyl article 15 minutes after application at 120° Celsius in ambient atmospheric air.

  • Publication number: 20090099311
    Abstract: A polyacrylic polymer is provided that is formed by moisture cure of multiple acrylic prepolymer segments. The prepolymer segments each have an average molecular weight of between 5000 and 400,000 grams per mole. Each of the prepolymers is a homopolymer or copolymer of a monomer from among methyl methacrylate, C1-C16 alkyl acrylate, and C1-C16 alkyl methyl methacrylate as the predominant monomeric group. The prepolymers are interconnected through moisture cure induced urea, urethane, or combinations thereof. The polymer is readily cured upon exposure to atmospheric moisture absent inclusion or evolution of a volatile organic compound. The polymer is likewise formed HAP free. Through control of prepolymer properties a variety of thermoset polymer properties are obtained. A prepolymer is formed including a minority amount of functionalized acrylic monomer that is isocyanate or converted to isocyanate through subsequent reaction.

  • Patent number: 4277025
    Abstract: A vibratory atomizer for atomizing a liquid, which atomizer comprises a nozzle portion from which the liquid is ejected, a body portion having vibration means, and a liquid inlet pipe which is attached to the body portion and which is made a number of half wave lengths long for the speed of sound in the pipe whereby in use of the vibratory atomizer energy radiated into the pipe reflects back into the body portion in phase.

  • Patent number: 4251031
    Abstract: An arrangement for supporting a vibratory atomizer for liquids, in which a nozzle for ejecting the liquid forms the end of a longitudinal passage in a decreasing-diameter resonant vibration-amplifier horn that extends from a body portion equipped with a generator for longitudinal vibrations, in a supporting structure with a minimum of interference with either the longitudinal vibrations or radial vibrations which accompany these longitudinal vibrations. The atomizer is clamped axially between two annular resilient support members one of which acts upon a flange-like shoulder surface of the atomizer perpendicular to the longitudinal vibration at the larger-diameter base of the amplifier horn and permits relatively unrestricted radial movement of the shoulder surface, while the other engages the horn surface in the vicinity of this plane along a line at which the horn surface intersects a nodal zone of zero radial vibration, where it acts to centralize the atomizer in addition to supporting it axially.

  • Patent number: 4000970
    Abstract: A process for the batdhwise dyeing of polyamide textile materials which comprises treating said material in an aqueous dye liquor containing not more than 10% by volume of at least one organic liquid capable of forming an azeotrope with water and an anionic dye, said dye liquor being maintained during at least part of the treatment at a temperature higher than the boiling point of said azeotrope and under a pressure greater than atmospheric pressure, and then recovering the organic liquid, by distillation before removing the textile material from the aqueous dye liquor.
