    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: Curable compositions, cured compositions formed from the curable compositions, and articles containing the cured compositions are provided. The curable compositions include (a) a curable component that includes (1) an epoxy resin, (2) a polyamide composition, (3) a multifunctional amine compound, and (4) a multifunctional (meth)acrylate compound and (b) an optional inorganic filler. The curable composition can result in the formation of cured compositions with properties such as good tensile strength, good elongation at break, good overlap shear strength, good adhesion to substrates such as metal substrates, or a combination thereof.

    Abstract: The present disclosure provides a two-part composition polymeric material including a first part and a second part. The first part includes an inorganic filler and a polymeric material including a polymerized reaction product of a polymerizable composition including components. 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 second part includes a polythiol having an average sulfhydryl group functionality of 2 or greater. 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.
