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 a thermally activatable amine curative, 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; and an optional second hydroxyl-containing compound having a single OH group. 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 liquid 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 curing a two-part composition. Advantageously, two-part compositions according to the present disclosure can be used as coatings and adhesive systems having a two-step cure with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water.
