Can You Buy Mek in California?

FAQs Jackson Bowman July 26, 2022

Is there a MEK ban in California? The short answer is Yes, MEK was banned in Southern California in 2011. California is one of the stricter states when it comes to laws on the use of VOCs.

Is MEK illegal?

The answer is no. Although MEK can be hazardous if used improperly, it is not believed to pose a significant threat to the user or the environment, so the EPA could ban the use of this chemical.

Why is MEK banned in the US?

On March 30, 1998, the EPA denied the application concluding that volatile organic compounds (VOCs) such as MEK contribute to the formation of tropospheric ozone, which is known to have significant adverse effects on human health and the environment .

What can I use instead of MEK?

MEK and acetone are both used as industrial solvents to strip and clean uncured and cured resins and coatings, as well as to clean pumps and other equipment. Because MEK is a slightly more aggressive chemical, some choose to replace MEK with acetone as a “safer” alternative.

Is acetone the same as MEK?

MEK or methyl ethyl ketone is stronger than acetone because it evaporates more slowly and boils at a higher temperature. Because of these differences, MEK can be a stronger cleaning agent than acetone.

What does MEK do to your body?

* Methyl ethyl ketone may affect you if inhaled and passed through the skin. * Methyl ethyl ketone may irritate skin and cause a rash or burning sensation on contact. Repeated contact can cause dehydration and cracking of the skin. * Contact can severely irritate and burn eyes, which may result in permanent damage.

Is MEK safe to use?

It may be harmful to eyes, skin and if inhaled or swallowed. Workers can be harmed by exposure to methyl ethyl ketone. The level of exposure depends on the dose, duration and work performed. Methyl ethyl ketone is used in many industries.

Can MEK cause liver damage?

MEKP causes severe upper gastrointestinal burns and liver necrosis.

Do you need a respirator for MEK?

A disposable mask cannot be used with MEK. It must be a reusable full-face respirator with cartridges for organic vapor chemicals up to 3000 PPM. Anything above 3000ppm workplace concentration would be intake air only.

Is MEK regulated as as VOC?

MEK is still regulated as a VOC. Methyl acetate has lower chemical reactivity in the air environment and is considered VOC-free.

Will MEK damage PVC?

If you use MEK to prepare the surface of your PVC or urethane material, use it sparingly. Excessive application can dissolve and damage the coating of the material.

Will MEK dissolve plastic?

MEK is used as an effective plastic welding agent. It can dissolve many plastics, including polystyrene and bind plastics together. MEK acts as a welder by dissolving the surface it is applied to and then evaporating – it acts more like a chemical welder.

Will MEK remove paint?

It can also cause eye and lung irritation, as well as dizziness and drowsiness. Methyl Ethyl Keytone (MEK): Also known as butanone, MEK is often used to wipe down surfaces before applying new paint or stain. It can be used to remove paint, glue, epoxy, grease and dirt.

Is MEK and paint thinner the same?

Replace the methyl ethyl ketone (MEK) based paint thinner with an alcohol based paint thinner. MEK, also known as butanone, is an organic solvent used in the paint and printing industry. It is used in the processing of rubber and resins, the manufacture of paraffin wax, varnishes and as a plastic welding agent.

How do I apply for MEK?

Use MEK to clean work surfaces from oxidation or other contaminants. This is done using a rag soaked in MEK until the color of the material is present on the rag. Allow the MEK to evaporate but immediately proceed with the adhesive application before the ‘softer’ texture of the cleaned surfaces fades.

Can I mix MEK and acetone?

The other chemical exposure conditions, MEK at 200 ppm and the combination of MEK with acetone, did not produce consistent statistically significant results, suggesting that there was no potentiation of acetone effects from co-exposure to MEK or vice versa under these test conditions.
