Detailed Product Overview
Methyl Ethyl Ketone (MEK), with the chemical formula C4H8O and CAS number 78-93-3, is a colorless liquid known for its excellent solvent properties. It features a sweet, acetone-like odor and a low molecular weight of 72.11 g/mol. MEK is miscible with water and has a low boiling point of 79.6 °C, which contributes to its volatility and effectiveness as a solvent. Its ability to dissolve a wide range of substances, including resins, polymers, and other organic compounds, makes it a critical component in industrial processes, particularly in the paints and coatings sector where rapid evaporation is often required. In industrial applications, Methyl Ethyl Ketone is predominantly used in the formulation of paints and coatings. Its rapid evaporation rate enhances the drying time of coatings, which is essential in high-speed production environments. MEK is also employed in adhesive production, where it acts as a solvent for adhesive components, ensuring proper mixing and application. In the plastic processing industry, it is used to clean molds and machinery due to its effective degreasing properties. Furthermore, MEK serves as a cleaning agent in various industrial settings, owing to its ability to dissolve oils, greases, and other contaminants. Kivi Industrial Chemicals Limited supplies MEK in industrial grade, tailored to meet the rigorous demands of different industrial applications. Buyers should verify the product's specifications upon receipt, including its density of 0.805 g/cm³, viscosity of 0.43 mPa.s at 25 °C, and refractive index of 1.378. Ensuring these parameters align with the provided specifications is crucial for maintaining consistency in production processes. Additionally, the product should be inspected for its appearance as a colorless liquid and its characteristic sweet, acetone-like odor to confirm purity and quality. Handling and storage of Methyl Ethyl Ketone require careful attention due to its flammable nature. It should be stored in a cool, well-ventilated area away from sources of ignition. MEK is typically supplied in 200 L plastic drums, which offer durability and protection against leaks. When handling MEK, appropriate personal protective equipment should be used to prevent exposure. Kivi Industrial Chemicals ensures that the packaging is compliant with UN1193 transport regulations, facilitating safe and efficient distribution across Kenya, Uganda, Tanzania, and the wider East African market. Customers are advised to consult the MSDS for detailed safety guidelines and ensure compliance with local environmental regulations.
