    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: A two-part curable composition is provided that includes a first part that includes an oxamido-containing compound and a second part that includes an epoxy resin. The oxamido-containing compound includes at least one first segment derived from a first polyamine and at least one second segment derived from a second polyamine that is different than the first polyamine. The oxamido-containing compound has at least two amino (—NH2) groups that can react with the epoxy resin in the second part of the curable composition. Each part of the curable composition is flowable, often at room temperature or slightly above room temperature, and can be mixed to form a cured composition having structural bonding performance.

    Abstract: Methods of bonding a male element and a female element, the method including applying an adhesive composition to at least the male element, the male element including a first metal; inserting at least a portion of the male element into the female element thereby forming an external interface between the male element and the female element, the female element including a second metal; and curing the adhesive composition to form an adhesive bond between the male element and the female element, wherein the first metal and the second metal are not the same, wherein the external interface of the male element and female element is covered by the cured adhesive composition and the adhesive composition covering the external interface of the male element and female element limits corrosion of at least a portion of the male element, the female element, or both.
