    Abstract: Articles are provided, including a substrate having a first major surface, the substrate including a nonwoven material, a woven material, or a foam. The article further includes microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules, where the plurality of microcapsules is attached to the first major surface of the substrate with a polymeric material. A method of making an article is also provided, including providing a substrate having a first major surface and providing microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules. The method further includes attaching the microcapsules to the first major surface of the substrate with a polymeric material, thereby forming a polymeric matrix attached to the first major surface of the substrate.

    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 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 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: Articles are provided, having a first substrate and a polymeric structure wrapped around the first substrate at least two full circuits. The polymeric structure has a length, a width and a thickness, and comprises a crosslinked polymeric layer uniaxially oriented in the width direction at a draw ratio of at least 1.2:1. The length is greater than the width. A method is also provided including providing a polymeric structure, wrapping the polymeric structure around a first substrate at least two full circuits, positioning the polymeric structure at least partially within an aperture defined by a second substrate, and subjecting the polymeric structure to an elevated temperature above the transition temperature of the crosslinked polymeric layer and below the degradation temperature of each of the components in the polymeric structure. The thickness of the polymeric structure increases, creating at least a partial joint between the first substrate and the second substrate.
