resinid

Resinid is a term that can refer to several different things within the realm of materials science and chemistry. Primarily, it is used to describe a synthetic resin or a substance that is resin-like in its properties. These materials are often polymers, characterized by their viscous liquid or solid state, and their ability to harden or cure into a durable, often insoluble and infusible, material. Synthetic resins are manufactured through chemical processes and form the basis of many plastics, adhesives, coatings, and composite materials.

The term "resinoid" is also sometimes used, particularly in older literature, to denote a thermosetting synthetic resin that has been partially cured but can still be molded or shaped. This partially cured state allows for processing before the final, irreversible hardening occurs. The specific chemical composition and properties of resinids or resinoids vary widely depending on their intended application. They can be based on epoxy resins, phenolic resins, polyester resins, and many other polymer types. Their utility stems from their ability to bind other materials together, provide protective coatings, or form structural components. Understanding the specific context in which "resinid" is used is crucial to pinpointing its exact meaning.
