  • Publication number: 20250154391
    Abstract: One-part (1K) and two-part (2K) cold bonding adhesive compositions for bonding vulcanized rubber compounds are described. The compositions can be used to bond vulcanized elastomers, such as chloroprene and buffed natural rubber, to themselves or to metal. The compositions can be free of hazardous chemicals often used in cold bonding adhesives, such as monomeric isocyanates and/or trichloroethylene or other chlorinated solvents. The adhesives also offer easy application and long pot life.

  • Patent number: 11279861
    Abstract: A curable adhesive that is particularly well suited for use in an injection or compression molding operation. The adhesive is based on polymeric resins having carboxylic acid and acrylate ester functionality, such as grafted phenoxy resin, and further constituents such as organic carbonates, blocked isocyanates, catalysts, maleimide compounds, hydride sources, and a carrier fluid. The curable adhesives are particularly well suited for bonding liquid injectable substrates such as liquid silicone rubber, or polyamides to rigid substrates, such as aluminum, stainless steel, or glass.

  • Publication number: 20180244965
    Abstract: An adhesive for bonding comprising a blocked isocyanate and organic carbonate, and optionally a phenoxy resin, catalyst, metal acetylacetonate, and a process for using such an adhesive to bond elastomers, such as liquid silicone rubber to substrates, such as polycarbonate in an injection molding process.

  • Publication number: 20110288260
    Abstract: Disclosed are benzoxazine compositions where oxazine rings are part of the polymer main-chain. The benzoxazine oligomers are prepared by the reaction of a bisphenol and an aldehyde, such as formaldehyde or paraformaldehyde, with one or more diamines or polyamines, and optionally with one or more monofunctional amines or monofunctional phenols. Also disclosed are benzoxazine monomers prepared from a bisphenol, an aldehyde, such as formaldehyde or paraformaldehyde, and a monofunctional amine, which benzoxazine monomers may be optionally used as reactive diluents. Further disclosed are benzoxazine monomers are prepared from a diamine, and aldehyde, such as formaldehyde or paraformaldehyde, and a monofunctional phenol, which benzoxazine monomers may also be optionally used as reactive diluents.
