    Abstract: The present disclosure provides a polymeric material including a polymerized reaction product of a polymerizable composition including components, a polythiol having an average sulfhydryl group functionality of 2 or greater, and an acidic stabilizer. The components include a uretdione-containing material including a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound having more than one OH group; and an optional second hydroxyl-containing compound having a single OH group. The 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 accelerator. 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 sealants, 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.

    Abstract: Disclosed herein are non-aqueous compositions including: a flowable Part A including at least one resin and Reactant A; and a flowable Part B including at least one resin and Reactant B; wherein at least one of flowable Part A and flowable Part B further includes a free radically polymerizable resin; wherein at least one of flowable Part A and flowable Part B further includes a free radical initiator system; wherein flowable Part A and flowable Part B are capable of being mixed to provide a flowable mixed composition; wherein when flowable Part A and flowable Part B are mixed, Reactant A and Reactant B are capable of interacting to cause a non-free radical reaction within a first staging time to provide a first staged stable consistency for the mixed composition; wherein Reactant A comprises an acid and Reactant B comprises a base, and upon mixing flowable Part A and flowable Part B, the Reactant A acid is capable of reacting with the Reactant B base in an ionic acid-base reaction; and wherein the mixed composition having the first staged stable consistency is capable of forming a hardened dental composition upon initiation of free radical polymerization.

    Abstract: The present disclosure provides a polymeric material including a reaction product of a polymerizable composition and having a solids content of 90% or greater. The polymerizable composition includes a uretdione-containing material including a reaction product of a diisocyanate reacted with itself, a first hydroxyl-containing compound having a single OH group, and a second hydroxyl-containing compound having more than one OH group. The first hydroxyl-containing compound is a primary alcohol or a secondary alcohol, plus the second hydroxyl-containing compound is a diol and the reaction product contains 0.2 to 0.5, inclusive, of diol equivalents relative to isocyanate equivalents. 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.
