Any of various yellowish viscous liquids or soft solids of plant origin; used in lacquers, varnishes and many other applications; chemically they are mostly hydrocarbons, often polycyclic.
Some resins also contain a high proportion of resin acids. The individual components of resin can be separated by fractional distillation. Rosins on the other hand are less volatile and consist inter alia of diterpenes. The composition of resins varies with the species.ertain casting resins and synthetic resins (such as epoxy resin) have also been given the name resin because they solidify in the same way as some plant resins, but synthetic resins are liquid monomers of thermosetting plastics, and do not derive from plants.
