Final answer:
Self-cured sealant materials are supplied as a two-part system that includes a base catalyst and an initiator polymer. These components work together to form a thermosetting polymer with desirable properties. Epoxy resins are commonly used as self-cured sealants in various applications.
Step-by-step explanation:
Self-cured sealant materials are supplied as a two-part system that includes a base catalyst and an initiator polymer. The base catalyst is responsible for initiating the cross-linking reaction, while the initiator polymer helps in the curing process. These two components work together to form a thermosetting polymer with desirable properties, such as mechanical strength and chemical resistance. For example, epoxy resins are commonly used as self-cured sealants in various applications, including metal coatings, electrical insulation, and adhesives.
