Curable compositions and related methods

Provided is a curable composition containing a reactive mixture of components including an polyethersulfone having a chemical group reactive with an epoxide, a cycloaliphatic polyepoxide resin, a polyepoxide having a functionality greater than two, a liquid diepoxide resin, a first curative containing 9,9-bis(aminophenyl)fluorene or a derivative therefrom and having a curing onset temperature of from 150° C. to 200° C. The components can further comprise a second curative having a curing onset temperature of from 60° C. to 180° C. When thermally curing this composition, the second epoxy curative starts to cure before the first epoxy curative, thereby inhibiting vertical flow of the adhesive during the curing process.

Thioester adhesives for apparel products

Embodiments provide adhesives for apparel products. The apparel product includes a major component and a minor component. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component of the apparel product forms a secondary portion and is configured to be coupled to the major component. An adhesive is disposed at least partially between a portion of the major component and a portion of the minor component. The adhesive includes a material having a thioester bond.

IGNITION-SUPPRESSING TAPE AND METHOD OF INSTALLATION

An ignition-suppressing tape for sealing cut edges of polymer panels, the tape having a backing strip and a sealant strip that is disposed on a portion of a surface of the backing strip, and a pressure sensitive adhesive is disposed on other portions of the same surface of the backing strip.

Methods of disassembling apparel products having disulfide adhesives

Embodiments provide methods of disassembling apparel products. The methods include exposing an adhesive of the apparel product to a composition having an acidic or basic pH. The adhesive is disposed at least partially between a major component and a minor component of the apparel product. The adhesive includes a material having a disulfide bond. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.
