Encapsulated Catalyst for Aerospace Grade Resin Systems

摘要

Methods and compositions, and components comprising the compositions, are disclosed relating to improved resin-based adhesives comprising encapsulating at least a catalyst compound. Further methods and compositions are disclosed relating to encapsulated catalysts in uncured resin-based adhesives, said encapsulated catalysts configured to release the catalyst compound and cure the uncured resin-based adhesive on-demand.
