摘要: The two-part composition includes a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, expandable graphite comprising moisture, and first polymeric microspheres having been at least partially coated with inorganic filler. The second part includes a second vinyl-substituted polysiloxane, a hydrosilyl-substituted polysiloxane, and second polymeric microspheres having been at least partially coated with flame-retardant inorganic filler. The two-part composition is useful, for example, for curing into a sealant and making an assembly. The assembly has a first substrate and a second substrate with a cured product of the two-part composition in contact with the first substrate and the second substrate. Methods of making a sealant and an assembly are also described.

摘要: Provided is a curative part usable in a two-part curable composition. The curative part includes a liquid amine; a heterogeneous dispersant; and core-shell rubber particles having an elastomeric core and a (meth)acrylic shell. The core-shell rubber particles and the heterogeneous dispersant can be collectively shear-dispersed in the liquid amine such that the core-shell rubber particles are substantially non-aggregated and the curative part is phase-stable over a period of at least 3 months at ambient temperature. Advantageously, large amounts of core-shell rubber particles can thus be incorporated into a cured resin matrix, which can afford significantly enhanced impact performance.

摘要: Provided are two-part curable adhesives that can be suitable for use in industrial bonding applications, including aero-space and automotive bonding. The adhesives include a first part that contains an epoxy resin and a first oligomeric toughener. The adhesives further include a second part comprising a curative that is reactive with the epoxy resin at ambient conditions and a second oligomeric toughener. The first and second oligomeric tougheners are immiscible with each other at ambient conditions. Advantageously, the adhesives when cured can simultaneously display both high shear strength and high peel performance at elevated temperatures.

摘要: A one-part primer composition is provided. The one-part primer composition includes a first epoxy resin that is a liquid under ambient conditions a particulate corrosion inhibitor present in an amount of from 5 wt % to 30 wt % relative to the overall weight of the composition excluding carrier solvents and water, a curative comprising a primary aromatic amine, a silane coupling agent, a carrier solvent; and water homogeneously mixed with the carrier solvent and present in an amount sufficient to hydrolyze the silane coupling agent while preserving solubility of the first epoxy resin and curative in the carrier solvent/water mixture. The corrosion inhibitor is pre-dispersed in a liquid epoxy to break the agglomeration of the inhibitors, mitigate settling of the pigment and improve primer performance.

摘要: Provided is a curable composition containing a reactive mixture of components including an polyethersulfone having a chemical group reactive with an epoxide, a cycloaliphatic polyepoxide resin, a polyepoxide having a functionality greater than two, a liquid diepoxide resin, a first curative containing 9,9-bis(aminophenyl)fluorene or a derivative therefrom and having a curing onset temperature of from 150° C. to 200° C. The components can further comprise a second curative having a curing onset temperature of from 60° C. to 180° C. When thermally curing this composition, the second epoxy curative starts to cure before the first epoxy curative, thereby inhibiting vertical flow of the adhesive during the curing process.

摘要: Provided are curable compositions including a base part comprising an amine-reactive curable resin and a curative part comprising a polymeric toughener dissolved in an amine. The polymeric toughener, optionally a rubbery polymer or thermoplastic polymer, is solid at ambient conditions with a weight average molecular weight of at least 5,000 g/mol while the amine is a liquid at ambient conditions. The curable composition is cured by mixing the base and curative parts with each other. Hardened compositions obtained thereof can achieve increased toughener loading, resulting in high peel and shear strength performance over a wide range of temperatures, including at temperatures exceeding 180° F. (82° C.).
