What is MEK (Methyl Ethyl Ketone)?
Methyl Ethyl Ketone (C4H8O) is an organic compound that is a strong, corrosive, naturally oxidizing agent. It is also referred to as Butanone or 2-Butanone, and while it is a particularly effective solvent itself, MEK solvent is soluble in alcohol and water. It is a liquid ketone with no color, and a sharp odor similar to acetone.
MEK is miscible with water and many organic solvents, making it a versatile choice for various applications. Key properties include:
- Chemical Formula: C4H8O
- Molecular Weight: 72.11 g/mol
- Boiling Point: 79.6°C (175.3°F)
- Flash Point: -9°C (15.8°F)
- Solubility in Water: 29.3 g/100 mL at 20°C
What is methyl ethyl ketone (MEK Solvent) used for?
1. Paints and Coatings
Methyl ethyl ketone is extensively used in the paints and coatings industry as a solvent for resins, lacquers, and varnishes. Its fast evaporation rate helps achieve a smooth, uniform finish on surfaces.
2. Adhesives
In the adhesives sector, MEK solvent acts as an effective solvent for cyanoacrylates, urethanes, and epoxies. It aids in manufacturing adhesive products and is also used to clean adhesive residues.
3. Printing Inks
MEK is utilized in the printing industry for flexographic and gravure inks. It dissolves a wide range of resins, resulting in inks with excellent drying and adhesion properties.
4. Cleaning and Degreasing
Due to its strong solvency and fast evaporation, 2-Butanone (MEK) is a popular choice for cleaning and degreasing metal surfaces. It effectively removes oils, greases, and other contaminants without leaving residues.
