Thermoset epoxy resin, its preparing composition and making process thereof

A thermoset epoxy resin, its preparing composition and making process are disclosed. In particular, the thermoset epoxy resin is glycidyl ether of diphenolic bis-carbamate and formed by curing a one component epoxy composition and has a general structure as shown in formula (1).

Polymeric Material Including a Uretdione-Containing Material and an Epoxy Component, Two-Part Compositions, and Methods

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 epoxy component is present in an amount of 35% by weight or greater, based on the total weight of the polymerizable composition. 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 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 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, or with performance similar to toughened epoxy systems.
