Resin

Resin is a solid or semi-solid plant- or synthetic-derived substance that is typically clear or amber in color and is used in varnishes, coatings, and castings. It originates from natural tree secretions or synthetic polymers and can be hardened when cured. In everyday usage, resin often denotes sticky, viscous material that becomes hard when heated or aged, and it’s also a term for the cured product itself.
