Replace Methyl Ethyl Ketone (MEK) based Paint Thinner with Alcohol based Paint Thinner

MEK, also known as Butanone, is an organic solvent used throughout the paint and print industry. It is used in processing involving gums and resins, production of paraffin wax, varnishes, as well as a plastic welding agent. MEK is highly flammable and considered to be mildly explosive. EPA lists MEK as a hazardous chemical. Studies have shown that MEK exposure has neurological and neuropathic effects on human. When used, stored or disposed of incorrectly, organic solvents can cause environmental problems such as air pollution, water and soil contamination, as well as being harmful to wildlife. The detrimental effects of MEK on occupational workers has economic as well as welfare issues. To overcome these challenges, many companies have developed custom alcohol based alternatives for MEK.

At a facility where the above recommendation is suggested, 2,440 gallons of MEK/yr has been replaced by alcohol based thinners. These are less volatile, environmentally friendly and less hazardous to human health, as compared to MEK. Preptone, created by blending ultra high-purity d-limonene in an acetone base can be a sustainable alternative. Unlike MEK, Preptone features terpene solvents which enable it to be even more powerful than most ketone solvents. The acetone present in Preptone is VOC exempt, this quality enables its vapors and VOC content to remain below regulatory limits. Other EPA allowed safer alternatives
