    摘要: A carborane siloxane base polymer is formulated into a crosslinked, rubbery high temperature material by incorporating a vinyl group in the backbone of the polymer. By careful control of process variables, the crosslinked polymer allows formation of optically clear and thermally stable adhesive bonds between a number of substrates. While curing is conveniently done at ambient temperature, the adhesive can withstand thermal cycling to over 600.degree. C.

    摘要: An aqueous adhesive composition containing a chlorosulfonated polyethylene latex, a polymaleimide compound, a nitroso compound and a metal oxide. The adhesive composition can be effectively utilized without a primer component and exhibits an unusually high resistance to pre-bake conditions and adverse environments. The adhesive also possesses the ability to effectively bond a variety of substrates.

    摘要: Novel structural adhesive systems for metal-bonding applications. The adhesives, comprising a solution or dispersion of a polymeric material in a monomer copolymerizable therewith having incorporated therein certain phosphorus-containing compounds, are characterized by an unexpected ability of providing strong adhesion to untreated metal surfaces without adversely affecting adhesive performance, including resistance to deleterious environments. The environmental resistance of the herein described adhesives can be further improved by the addition of one or more polybasic lead salts, metal molybdates and metal phosphates.

    摘要: Inclusion of an effective amount of substantially anhydrous acetic acid in a zinc oxide cured liquid polysulfide polymer based composition results in a cured composition which is suitable for extrusion under heat and pressure and which on cooling reverts to a rubbery solid with essentially unchanged physical properties. The compositions are useful for the manufacture of sealants and extrudible goods such as hoses.
