  • Patent number: 10392543
    Abstract: Disclosed is a highly fluorinated silicone resin and a method for making the same. The silicone resin includes M, T, optionally D and optionally Q type monomers and is crosslinkable. The resin has a fluorine content of at least 55 weight percent and a very low refractive index of less than 1.4. The resin is formed in a one step process and requires use of very specific solvents. Preferably the resin includes a first T type monomer having a fluoroalkane group to provide the fluorine to the resin. Preferably the resin includes a second T type monomer having a (meth)acryloyl function to enable cross-linking. The resin forms an effective liquid optically clear adhesive. The resin can be further combined with highly fluorinated (meth)acrylate monomers or perfluoro polyethers to provide even lower refractive indexes and improved adhesive properties.

  • Publication number: 20190218434
    Abstract: Provided herein are conductive formulations which are useful for applying conductive material to a suitable substrate; the resulting coated articles have improved EMI shielding performance relative to articles coated with prior art formulations employing prior art methods. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. Specifically, invention methods utilize capillary flow to substantially fill any gaps in the coating on the surface of an electronic package. Effective EMI shielding has been demonstrated with very thin coating thickness.

  • Publication number: 20190169478
    Abstract: Dual-cure compositions for use in high temperature adhesive applications, and particularly for temporarily adhesively attaching one substrate to another substrate, are provided. These dual-cure adhesives are silicone-based compositions that can be B-staged by exposure UV radiation to provide initial green strength, followed by a C-stage cure to give adhesives that can survive high temperature processes above 200° C., especially above 300° C., yet easy to debond afterwards to allow separation of the top and bottom substrates.

  • Publication number: 20040131873
    Abstract: The present invention is directed to a pressure sensitive adhesive (PSA) composition containing a copolymer of a vinyl ester and ethylene, formed by emulsion polymerization. The ethylene level of the copolymer is from 40 to 75 weight percent. The copolymer is free of carboxyl-functional monomer units. The copolymer preferably also contains a non-carboxyl functional monomer. The PSA is useful for labels, decals, repositionable notes, and different types of tape. Labels containing the PSA adhere especially well to non-polar substrates.
