Main Difference
The main difference between Rosin and Resin is that the Rosin is a organic substance and Resin is a solid or highly viscous substance of plant or synthetic origin.
Rosin
Rosin, also called colophony or Greek pitch (Latin: pix græca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperature. It chiefly consists of various resin acids, especially abietic acid. The term “colophony” comes from colophonia resina, Latin for “resin from Colophon”, an ancient Ionic city.
Resin
In polymer chemistry and materials science, resin is a “solid or highly viscous substance” of plant or synthetic origin that is typically convertible into polymers. They are often mixtures of organic compounds, principally terpenes. Many plants, particularly woody plants, produce resin in response to injury. The resin acts as a bandage protecting the plant from invading insects and pathogens.
Rosin (noun)
A solid form of resin, obtained from liquid resin by vaporizing its volatile components.
Rosin (noun)
Resin
Rosin (verb)
To apply rosin to (something); to rub or cover with rosin.
“We waited expectantly as the guest violinist rosined his bow in preparation to playing.”
Resin (noun)
A viscous hydrocarbon secretion of many plants, particularly coniferous trees.
Resin (noun)
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.
Resin (noun)
Any synthetic compound of similar properties.
Resin (verb)
To apply resin to.
Rosin (noun)
resin, especially the solid amber residue obtained after the distillation of crude turpentine oleoresin, or of naphtha extract from pine stumps. It is used in adhesives, varnishes, and inks and for treating the bows of stringed instruments
“liquid rosin flux”
“they will also supply crushed colophony rosin”
Rosin (verb)
rub (something, especially a violin bow or string) with rosin
“island musicians are rosining their bows”
Resin (noun)
a sticky flammable organic substance, insoluble in water, exuded by some trees and other plants (notably fir and pine)
“clear resin had oozed to the surface, trickled down, and set”
Resin (noun)
a solid or liquid synthetic organic polymer used as the basis of plastics, adhesives, varnishes, or other products
“epoxy resins frequently cause dermatitis”
“the chassis is constructed of synthetic resin”
Resin (verb)
rub or treat with resin
“resined canvas”
