1. A polymeric material comprising:
a polymerized reaction product of a polymerizable composition comprising components, the components comprising:
(a) a uretdione-containing material comprising a reaction product of a diisocyanate reacted with itself;
(b) a first hydroxyl-containing compound having more than one OH group;
(c) an optional second hydroxyl-containing compound having a single OH group, wherein the second hydroxyl-containing compound is a primary alcohol or a secondary alcohol; and
(d) an epoxy component;
wherein the polymeric material comprises a solids content of 90% or greater and exhibits a dynamic viscosity of 10 Poise (P) to 10,000 P, inclusive, as determined using a Brookfield viscometer.
