Methyl Ethyl Ketone in Bulk

Description

TECHNICAL DATA SHEET

METHYL ETHYL KETONE(URETHANE GRADE)


Product Name:

Methyl ethyl ketone

Product category:

Ketone

Molecular Formula: C4H8O

Structural Formula


CH3 – CH2 – C=O

CAS No.: 78-93-3

Description

Methyl ethyl ketone, MEK, a low boiling, fast evaporating solvent is a colorless, stable liquid, partially miscible with water. Methyl ethyl ketone displays exceptionally good solvency for most resinous materials including epoxy resins, nitro-cellulose, ethyl cellulose, cellulose-aceto-butyrate, alkyd, polyester, polyurethane, acrylic resins, vinyl polymers and copolymers. Also readily dissolved are practically all synthetic and natural resins commonly employed in the formulation of printing inks, lacquers, and other types of coatings. In addition, its complete miscibility with most other solvents as well as alcohols and hydrocarbon diluents makes methyl ethyl ketone a highly desirable and versatile solvent in surface coating applications.
