  • Patent number: 8937141
    Abstract: The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Mn(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Mn(III) complexes are comparable or superior to organotin such as DBTDL, superior to Mn(II) compounds, and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.
    Type: Grant

  • Patent number: 7230046
    Abstract: A flame-retardant composition is described, containing a thermoplastic resin component which includes polyphenylene ether (PPE), along with a low-melting glass having a glass transition temperature (Tg) of less than about 500° C. The low-melting glass contains phosphate, and at least one of RO; R?2O; Al2O3; B2O3; or SO3, where R is a bivalent metal, while R? is an alkali metal. Related articles are also described.

  • Publication number: 20040102549
    Abstract: A flame retardant thermoplastic resin composition comprises a thermoplastic resin comprising a polyphenylene ether resin, a high impact polstyrene resin or an acrylonitrile-butadiene-styrene resin; an organo phosphate compound in an amount less than or equal to about 20 parts by weight for every 100 parts by weight of the thermoplastic resin; and a polyhydric alcohol compound in an amount of about 0.5 to about 5.0 parts for every 100 parts by weight of the thermoplastic resin. A method for the manufacture of the thermoplastic resin composition is also disclosed. The thermoplastic resin composition exhibits high flow characteristics and improved impact strength while providing effective flame retardance.
