    Abstract: A method for adhering surfaces together using fast curing epoxy resin compositions is provided. The method includes the steps of mixing together (a) a curable glycidyl ether epoxide group-containing compound, (b) an amino-terminated aliphatic polyether curing agent, (c) a polymeric toughening agent having both a rubbery phase and a thermoplastic phase or being capable of forming, with the epoxide group-containing material, both a rubbery phase and a thermoset phase on curing, and (d) a metal salt catalyst capble of providing an exotherm of at least 20.degree. C.; applying the resulting mixture to a portion of at least one surface; contacting the surface having the mixture applied thereto to a second surface in bonding relationship with the mixture disposed between the surfaces; and curing the mixture.

    Abstract: Two-part polymerizable compositions are described which contain (a) organic material having epoxide functionality, (b) organic material having hydroxyl functionality, and (c) a catalyst comprising highly fluorinated aliphatic sulfonyl protonic acid or a compound capable of liberating such acid. The compositions polymerize essentially completely at room temperature (or at slightly elevated temperatures). The polymerized compositions have desirable dielectric properties and are therefore especially useful for potting electrical components.

    Abstract: A method of assembling a structure comprises applying an epoxy composition to at least one of a first member and a second member, sandwiching the epoxy composition between the first and second members, and bonding the two members wherein the adhesive bond is a thermally cured mass. The epoxy composition contains an epoxy resin, a phenolic or amine compound as a chain extender, a basic catalyst and a polymeric toughener. The composition can be formulated in two parts wherein part A contains the catalyst and part B has the epoxy resin.
