    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: A two-part curable composition comprises a Part A and a Part B. Part A composition includes uretdione-containing compound having an average uretdione ring functionality of at least 1.2. Part B composition includes polythiol having an average sulfhydryl group functionality of at least 2. At least one of the Part A composition and the Part B composition may further comprise accelerator for addition of the polythiol to the uretdione-containing compound. The accelerator comprises a nonacidic amine curative. The amine curative does not comprise a substituted or unsubstituted amidine group. Cured compositions, methods of making them and articles including them are also disclosed. A two-part composition without accelerator is disclosed wherein the uretdione-containing compound has at least one pendant —CH2NR42 groups, wherein each R4 independently represents an alkyl group having from 1 to 8 carbon atoms, or two R4 groups taken together form an alkylene group having from 2 to 8 carbon atoms.
