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.

Provided is a method of manufacturing self-adhesive polyurethanes using selective photo-polymerization. The method of manufacturing self-adhesive polyurethanes using photo-polymerization relates to a method for manufacturing photo-polymerized self-adhesive polyurethane substrates applicable to biocompatible epidermal soft sensors and attachable epidermal thermal heaters without particularly adding an adhesive additive.
