  • Patent number: 5954907
    Abstract: This invention relates to a process for applying a coating material comprising a release coating composition or a pressure sensitive adhesive composition to a substrate, the process comprising: (A) atomizing and electrically charging said coating material; and (B) spraying the atomized and charged coating material from step (A) on to a substrate which overlies a grounded support structure. In one embodiment, the coating material sprayed during step (B) is a release coating composition, said process further comprising the additional steps of: (C) curing said release coating composition; (D) atomizing and electrically charging a pressure sensitive adhesive composition; (E) spraying the pressure sensitive adhesive composition from step (D) on to said substrate over the cured release coating composition from step (C); and (F) placing another substrate over the sprayed pressure sensitive adhesive composition from step (E).

  • Patent number: 5879759
    Abstract: A two-step method is provided for the production of a pressure sensitive adhesive by radiation curing. The method comprises the steps of initially irradiating a monomer composition comprised of 65 to 100 percent by weight of monomers having a Tg<0.degree. C. to form a coatable syrup, followed by adding at least one monomer having a Tg>0.degree. C. and at least one multifunctional monomer or oligomer to said syrup, and further irradiating the mixture to form a pressure sensitive adhesive.

  • Patent number: 5879758
    Abstract: An improved method for manufacture of coated fiber material, for example a composite fly fishing line, is disclosed. The method includes coating fiber of a first material with a hot melt adhesive material. For fly lines, indices of refraction of the materials are preferably selected so that the finished product is substantially transparent absent addition of pigment. The coated fiber material is exposed to electron beam treatment to improve the physical profile of the coating.

  • Patent number: 5547753
    Abstract: Novel aminoplast anchored UV stabilizers are provided. Compared to unanchored stabilizers, the anchored stabilizers disclosed herein have increased compatibility with coating resins and have reduced volatility due to higher molecular weights resulting from anchoring. A process for preparing the anchored stabilizers by the reaction of unanchored stabilizers with alkoxymethylated aminoplasts in a sulfuric acid medium is also provided. The unanchored stabilizers include 2-(2-hydroxyaryl)benzotriazoles, 2-hydroxybenzophenones, 2-(2-hydroxyaryl)-4,6-diaryl-1,3,5-tri-azines, salicylic acid derivatives, 2-hydroxyoxanilides, and blocked derivatives thereof as well as mixtures of two or more stabilizers. The aminoplasts include alkoxymethylated derivatives of glycolurils, melamines, and benzoguanamines.

  • Patent number: 5529822
    Abstract: The present invention relates to a process for forming a laminate and the laminate using silicone release coating compositions comprising (A) a mixture of (i) a dimethylsiloxane-methylvinylsiloxane-methylphenylsiloxane copolymer and (ii) a dimethylsiloxane-methylvinylsiloxane copolymer, (B) an organohydrogenpolysiloxane, (C) a platinum catalyst, and (D) an organic solvent. The silicone release coating compositions of the present invention provide small release resistance values both at low and high peeling velocities and do not impair the residual adhesion of tacky substances that have come into contact with the coating.

  • Patent number: H1631
    Abstract: The present invention is a method for making radar chaff consisting of metal rings having varying diameters, using photolithographic processes. One aspect of the invention has the steps of: providing a metal foil having a thickness suitable for use in radar chaff; overcoating the metal foil with a photoresist, to form a layered structure; undercoating the metal foil with a removable backing; exposing the photoresist to a quantity of actinic radiation for chemically modifying the photoresist into a photoproduct suitable for subsequent development, where the actinic radiation is patterned into a series of concentric rings; developing the photoresist, to expose the underlying metal in a series of concentric rings; removing the exposed metal to form a series of concentric metal rings on the removable backing; and removing the removable backing. Another aspect of the invention is a metal chaff precursor, comprising: a removable backing, coated with a plurality of concentric metal foil rings.
