Description
2-Butanone is a stable, highly flammable chemical. It is incompatible with oxidising agents, bases, and strong reducing agents. It is a colourless liquid with a sharp, sweet odour. 2-Butanone is produced in large quantities. It is used as a solvent and nearly half of its use is in paints and other coatings because it will quickly evaporate into the air and it dissolves many substances. It is also used in glues and as a cleaning agent.

Application
1. It is used as a solvent for various coating systems, for example, vinyl, adhesives, nitrocellulose, and acrylic coatings. It is used in paint removers, lacquers, varnishes, spray paints, sealers, glues, magnetic tapes, printing inks, resins, rosins, cleaning solutions, and for polymerization. It is found in other consumer products, for example, household and hobby cements, and wood-filling products. MEK is used in dewaxing lubricating oils, the degreasing of metals, in the production of synthetic leathers, transparent paper and aluminum foil, and as a chemical intermediate and catalyst. It is an extraction solvent in the processing of foodstuffs and food ingredients. MEK can also be used to sterilize surgical and dental equipment.
2. It is a solvent inpaints and coatings. MEK is extensively used as a solvent in paint and coating formulations. It effectively dissolves various resins and polymers, making it ideal for high-performance coatings. In automotive paints, it helps achieve the desired viscosity and evaporation rate, contributing to a smooth, even finish on vehicles. MEK is also prevalent in industrial coatings due to its strong solvency and quick-drying properties.
3. MEK dissolves rubber, creating high-strength and flexible adhesives. It’s beneficial in pressure-sensitive adhesives found in tapes and labels. MEK-based adhesives are known for their strong bond and durability, especially in bonding materials like plastics, metals, and composites.
4. MEK is crucial in the printing industry, especially flexographic and gravure printing inks. It dissolves ink components effectively, providing the right consistency for printing processes. MEK ensures quick drying and high-quality print on various substrates, including plastics, making it suitable for packaging and labeling.
5. As a cleaning agent, MEK is employed to degrease and clean machinery, tools, and metal parts. Its ability to dissolve oils, greases, and other contaminants makes it valuable in maintenance and refurbishing. MEK is also used in the electronics industry for cleaning components during manufacturing and repair.
6. In pharmaceuticals, MEK extracts and purifies certain drugs and pharmaceutical ingredients. Its solvent properties enable the effective extraction of active components, which are vital in producing various medicinal products.
7. MEK is used as a welding agent in the plastics industry, particularly for joining pieces of polystyrene, ABS, and acrylics. It works by dissolving the surfaces of the plastic parts to be joined, forming a solid bond upon evaporation. This application is vital in industries that require the fabrication of plastic components and products.
8. MEK is used to clean and degreasing electronic components, especially during assembly. Its effectiveness in removing flux residues and other contaminants ensures the reliability and performance of electronic devices.
