Safe and Economical Acetone Replacement

MEK vs. Acetone

MEK and acetone are both used as industrial solvents for stripping and cleaning uncured and cured resins and coatings, and for cleaning pumps and other equipment. Since MEK is a slightly harsher chemical, some choose to replace MEK with acetone as a “safer” alternative.

Methyl Ethyl Ketone (MEK)

Methyl ethyl ketone (MEK) is a colorless liquid that has a sweet odor and is soluble in water. It is a highly volatile chemical and is frequently used as a commercial cleaner and solvent for glues, paints, coatings, and printing inks.

Workers are exposed to MEK when the vapors are present in the air or by absorbing the product through their skin. To prevent health issues, it is required that protective gear is worn while handling or working with MEK. Since MEK is flammable, extreme caution must also be taken when shipping or storing the product.

MEK Safety Risks

  • Flammability Rating of 3 (severe)
  • Contact rating of 2 (moderate)
  • Health rating of 2 (moderate)
  • Reactivity rating of 1 (slight)
  • Requires use of protective equipment

MEK Health Risks

  • Nose and throat irritant
  • Eye irritation caused by vapors
  • Central nervous system depression under high concentrations or after chronic exposure
  • Skin irritant that causes redness and itching


Acetone is a colorless, highly volatile liquid that dissolves in water. Like MEK, it is commonly used in industrial applications as a solvent for resins, waxes, oils, fats, lacquers, varnishes and other coatings and adhesives.

People often replace MEK with acetone in their industrial applications because it is somewhat less toxic than MEK, but it carries many of the same health and safety risks. Prolonged exposure to acetone is especially dangerous. At high levels, its vapors can cause central nervous system issues, cardiorespiratory failure, or even death.

Acetone Safety Risks

  • Flammability rating of 3 (severe)
  • Contact rating of 3 (severe)
  • Health rating of 2 (moderate)
  • Requires use of protective equipment

Acetone Health Risks

  • Vapors cause respiratory tract irritation
  • Eye irritant
  • Severe irritation or dermatitis with prolonged skin contact
  • Cases coughing, dizziness and headache if vapors are inhaled
  • High concentrations can result in nervous system depression or unconsciousness

A Safer Alternative to Using MEK or Acetone Solvents

When deciding between MEK vs. acetone, consider the health and safety risks, as well as the environmental impact. Both are highly flammable, pose a health risk when inhaled, and require the use of safety gloves to protect skin from exposure. Fortunately, there is a safer alternative that delivers the same results without the added health risks and safety and environmental hazards.

AcraStrip can strip and clean cured and uncured resins, gel coats, urethanes and other coatings, and for finish and surface preparation. It has even been shown to thin and clean more effectively than standard solvents due to its unique chemistry. Another benefit of AcraStrip products is that they do not require the use of protective gear and are even safe to use for cleaning resins and adhesives off the skin.

Advantages of using AcraStrip as a replacement for MEK or acetone include:

  • Non-flammable
  • No environmentally hazardous ingredients
  • Produces no hazardous fumes
  • Does not require SARA 313 reporting
  • Zero HAP content
  • pH neutral
  • Biodegradable
