PURE MEK Methyl Ethyl Ketone
Methyl ethyl ketone is a colourless, volatile, highly flammable liquid with a fruity odour
It is widely used as a solvent for protective coatings, paints, plastics, adhesives, printing inks and pesticides, it may be released from industry but it is quickly broken down in the environment, methyl ethyl ketone is produced naturally at low levels by many living things, methyl ethyl ketone can be found in various food items including meat, fruit and vegetables, people may be exposed to methyl ethyl ketone as an ingredient in some consumer products such as varnishes

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 is soluble in alcohol and water. It is a liquid ketone with no colour, and a sharp odour similar to acetone. In fact, MEK and acetone share similar chemical compounds. MEK is favoured for its strength over acetone, as it boils at a higher temperature and has a slower evaporation rate.
It has a boiling point of 175.4°F (79.64°C), a molar mass of 72.11 g/mol, and a molecular density of 0.8049 g/mL. While MEK is a predominantly manufactured chemical used for industrial purposes, it can also be found in trace amounts in nature.


1. Cleaning agent
Because MEK is naturally corrosive, it is a strong degreaser and can also be used to remove adhesives and other coatings from surfaces. MEK can be used to remove residual glue, dirt, grease, paint, or older coating layers that are starting to erode. MEK is often used to clean surfaces before new paint or parts are installed. It is sometimes used as a step in refurbishing products before reuse.

2. In petrochemical plastics
MEK can be used as a hardener in the manufacturing of resins, synthetic rubber, and as a solvent in making other chemicals for plastic production.

3. Paints, dyes, and glue
If you’ve ever smelled the distinct, sharp scent of a dry-erase marker, you’ve used a product of methyl ethyl ketone. MEK’s slow evaporating properties make it a useful ingredient in products like dry-erase markers. It is used as a solvent in the dye to ensure the ink flows properly. MEK is also a common ingredient in paint and paint products, like lacquer and other varnishes; as well as paint remover and glue.

4. Curing agent
MEK is commonly found in the fiberglass and plastic manufacturing industry. It is used as a curing agent for unsaturated polyester resins and fiberglass plastics. MEK is what’s known as a catalyst in this process for both vinyl and polyester resins. MEK cures the resin by reacting with it to solidify it from a liquid state.

5. In bonding and manufacturing
MEK is used as an effective plastic welding agent. It can dissolve many plastics, including polystyrene, and can bind plastics together. MEK works as a welding agent by dissolving the surface where it is applied and then evaporating – acting as more of a chemical welding agent. It can also be used to manufacture plastics themselves, as well as textiles, and paraffin wax.
