Gum Rosin WW

Gum rosin WW, also known as wood rosin, is a type of rosin that is derived from the sap of certain pine trees. It is a pale yellow to yellowish-brown, semi-transparent, brittle solid that is used primarily as a raw material in the production of chemicals, adhesives, and various other industrial products. It is composed mainly of resin acids and their esters, and it has a relatively high acid value compared to other types of rosin. Gum rosin WW is used in many industrial applications, including as a raw material in the manufacture of soaps, varnishes, adhesives, and rubber compounds. It is also used as a flux in soldering and tinning, as a lubricant, and as a raw material in the production of synthetic resins.
