    Abstract: The crosslinked polymer particles include a plurality of pendent tertiary amine groups and at least 20 percent by weight poly(alkyleneoxy) crosslinking segments, based on the total weight of the crosslinked polymer particles. Further particles include cores of crosslinked polymer particles having a plurality of tertiary amine groups and shells of an inorganic salt encapsulating the cores. The inorganic salt includes a multivalent cation and a multivalent anion. Compositions and articles including the particles and processes for making the particles and the crosslinked polymer particles are also described.

    Abstract: The present invention relates to an epoxy adhesive composition, comprising: a) 10-50 parts by weight of a bisphenol A epoxy resin, a bisphenol F epoxy resin, or a combination of a bisphenol A epoxy resin and a bisphenol F epoxy resin, wherein the epoxy equivalent weight thereof is 150-250 g/Eq; b) 20-50 parts by weight of a dihydroxy phenol glycidyl ether epoxy resin having an epoxy equivalent weight of 100-150 g/Eq; c) 1-5 parts by weight of a silane coupling agent; d) 20-60 parts by weight of a polyetheramine curing agent; e) 10-40 parts by weight of a filler; and f) 0-10 parts by weight of an imidazole accelerator. The epoxy adhesive composition provided by the present invention has a good workability and curing process operability. In addition, an epoxy adhesive prepared from the epoxy adhesive composition has a good peel strength on a plastic surface and good resistance to water vapor permeation.

    IPC: C08G18/79

    Abstract: The present disclosure provides a polymeric material including a polymerized reaction product of a polymerizable composition including components and an inorganic filler. The components include a uretdione-containing material including a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound; and an optional second hydroxyl-containing compound having a single OH group. The present disclosure also provides a two-part composition, in which the polymeric material is included in the first part and the second part includes at least one amine. Further, a method of adhering two substrates is provided, including obtaining a two-part composition; combining at least a portion of the first part with at least a portion of the second part to form a mixture; disposing at least a portion of the mixture on a first substrate; and contacting a second substrate with the mixture disposed on the first substrate. The disclosure also provides a polymerized product of the two-part composition and a battery module. Advantageously, two-part compositions can be used as coatings and adhesive systems including high loadings of inorganic filler, such as thermally conductive filler, with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water.

    Abstract: The present disclosure provides a polymeric material including a polymerized reaction product of a polymerizable composition including components and has a solids content of 90% or greater. The components include a uretdione-containing material including a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound; an optional second hydroxyl-containing compound having a single OH group, wherein; and an epoxy component. The epoxy component is present in an amount of 35% by weight or greater, based on the total weight of the polymerizable composition. The first hydroxyl-containing compound has more than one OH group and the optional second hydroxyl-containing compound is a primary alcohol or a secondary alcohol. The present disclosure also provides a two-part composition, in which the polymeric material is included in the first part and the second part includes at least one amine. Further, a method of adhering two substrates is provided, including obtaining a two-part composition; combining at least a portion of the first part with at least a portion of the second part to form a mixture; disposing at least a portion of the mixture on a first substrate; and contacting a second substrate with the mixture disposed on the first substrate. The disclosure also provides a polymeric material and a method of making a two-part composition. Advantageously, two-part compositions can be used as coatings and adhesive systems with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water, or with performance similar to toughened epoxy systems.
