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.

Abstract: Composite particles are provided that can be used to cure epoxy resins. More particularly, the composite particles have a porous polymeric core particle, a curing agent and/or a curing catalyst for an epoxy resin positioned within the porous polymeric core particle, and a fluoropolymer-containing coating layer around the porous polymeric core particle. Additionally, curable compositions are provided that are mixtures containing an epoxy resin and the composite particles. The epoxy resin typically does not react until the curable composition is heated causing the release of the curing agent and/or curing catalyst from the composite particle. Further, cured compositions formed from the curable composition are provided.

Abstract: A method of making an adhesive is provided, including obtaining an actinic radiation-polymerizable adhesive precursor composition disposed against a surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. The first portion and the second portion are adjacent to or overlapping with each other and the first irradiation dosage and the second irradiation dosage are not the same. The method forms an integral adhesive having a variable thickness in an axis normal to the surface of the actinic radiation-transparent substrate. Also, an adhesive article is provided, including a substrate having a major surface and an integral adhesive disposed on the major surface of the substrate. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

Abstract: A curable adhesive composition includes a curable epoxy resin, an amine curing agent, a toughening agent, and aluminum flakes. The aluminum flakes include a fatty acid milling aid on at least a portion of their surfaces. The aluminum flakes were heated after milling. An article includes an adhesive composition cured between at least two members. The cured adhesive composition includes the heat-treated aluminum flakes within a toughened epoxy resin cured with an amine curing agent. The method includes applying the curable adhesive composition of described above to a surface of at least one of two or more members, joining the members so that the curable adhesive composition is sandwiched between the two or more members, and curing the curable adhesive composition to form an adhesive bond between the two or more members.

Abstract: The present disclosure provides a redox initiator system for initiating polymerization comprising an oxidizing agent, a photolabile reducing agent derived from a barbiturate, and a transition metal complex that participates in a redox cycle. On exposure to actinic radiation, such as UV, the photolabile compound photolyzes, releasing the reducing agent and initiating the redox-initiated polymerization.
