resin
Let an agent explain resins and their kinds, relay natural and synthetic resins, properties and uses from materials sources, describe the bituminous materials the registry aliases name, and distinguish resin from bitumen and asphalt as a class, from gums and latex and from the fossilised resin amber.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain resins and their kinds, relay natural and synthetic resins, properties and uses from materials sources, describe the bituminous materials the registry aliases name, and distinguish resin from bitumen and asphalt as a class, from gums and latex and from the fossilised resin amber.
A solid or highly viscous substance of plant, animal or synthetic origin that hardens or cures, from natural resins such as pine rosin, amber and shellac through synthetic resins such as epoxy, polyester and acrylic to bituminous and asphaltic materials the registry groups here, including rock asphalt, albertite, goudron or tar, rubber and copolymer modified bitumens and coloured asphalt; resins are used as adhesives, coatings, varnishes, plastics and binders.
What it is for: Adhesives, coatings, plastics and binders.
It can be explain kinds and properties; relay uses; describe bituminous materials; distinguish related materials.
Distinguishing features
Hardening or curing
Natural and synthetic
Adhesive and coating use
Bituminous relatives
What it looks like
A sticky or glassy substance, amber to black.
Physical character
natural resin source: conifer and other plant exudates note
epoxy resin introduced: 1930s-1940s period
albertite: solid hydrocarbon from New Brunswick note
How it is recognised
Hardening viscous substance
Rosin, amber, shellac, epoxy, polyester; goudron, rock asphalt, albertite, modified and coloured asphalt
Bitumen and asphalt are petroleum or natural hydrocarbons; gums dissolve in water; latex is a dispersion

- The registry entry has merged aliases naming bituminous materials; should they be split off?
