    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.

    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; an epoxy component; and an accelerator. 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 a polymeric material is included in the first part and the second part includes at least one thiol-containing compound. 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 according to the present disclosure 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.

    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 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.
