Methyl ethyl ketone (MEK) is a colorless, flammable liquid organic compound with the chemical formula C4H8O. It is a ketone, which means it contains a carbonyl group (C=O) bonded to two carbon atoms. MEK has a sweet, pungent odor and is commonly used as a solvent in various industrial applications such as coatings, adhesives, and printing inks. It can also be used as a chemical intermediate in the production of other chemicals. MEK is highly volatile and can pose health hazards if not handled properly.

Petroleum resin C9 hydrocarbon, also known as C9 hydrocarbon resin or simply C9 resin, is a type of thermoplastic resin that is derived from the distillation of petroleum products. It is composed primarily of aliphatic and aromatic hydrocarbons, and is typically produced by the polymerization of C9 fraction of petroleum, which is obtained by the distillation of crude oil. C9 hydrocarbon resin is a highly versatile material that finds use in a wide range of industrial applications, including adhesives, coatings, printing inks, rubber compounding, and more. It is valued for its excellent solubility, compatibility with other resins, and ability to enhance the properties of other materials, such as adhesion, tack, and flexibility. In summary, petroleum resin C9 hydrocarbon is a type of polymer derived from petroleum that is widely used in various industries for its unique properties and compatibility with other materials
