About Methyl Ethyl Ketone (MEK)

Buy methyl ethyl ketone (MEK, CAS 78-93-3) from Alliance Chemical in Technical and ACS grades. MEK is a strong, fast-evaporating ketone solvent used in coatings, adhesives, resin systems, industrial cleaning, and laboratory solvent applications.

Products In This Collection

This collection includes MEK Technical Grade for production solvent use and MEK ACS Grade for reagent and quality-sensitive applications. Both grades support buyers who need strong solvency, fast evaporation, and reliable documentation.

Common Applications

  • Coatings and inks: MEK is widely used in solvent-borne coating, ink, and resin systems where evaporation profile and solvency are key process variables.
  • Adhesives and polymer processing: MEK helps dissolve or soften compatible resins, polymers, and adhesive systems in production and repair workflows.
  • 3D print and fabrication cleanup: MEK can be used in specialized finishing or bonding workflows where material compatibility has been confirmed.
  • Industrial degreasing: Technical Grade MEK removes oils, processing residues, and coating soils from compatible metal and equipment surfaces.

Grade & Selection Notes

Choose Technical Grade MEK for general industrial solvent use, coatings, adhesives, and cleanup. Choose ACS Grade MEK when your lab, QA, or customer specification requires reagent-grade purity and tighter impurity control.

Safety & Handling

MEK is a highly flammable solvent. Use with strong ventilation, keep away from ignition sources, avoid incompatible oxidizers, and confirm material compatibility before applying it to plastics or coatings. Review the Safety Data Sheets before use and follow your site-specific handling procedure.

Why Buy From Alliance Chemical

Most in-stock MEK orders ship in 1-2 business days with SDS availability and lot-specific COA support for qualifying orders.

Frequently Asked Questions

What is MEK used for?
MEK is used in coatings, adhesives, resin processing, degreasing, laboratory solvent work, and compatible plastic or polymer workflows.
How does MEK compare with acetone?
Both are fast ketone solvents. MEK generally evaporates more slowly than acetone and is often selected for coatings, adhesives, and resin systems that need more working time.
Is MEK available in ACS Grade?
Yes. Alliance Chemical offers MEK in ACS Grade for reagent and quality-sensitive applications, along with Technical Grade for industrial use.
Can MEK damage plastics?
Yes. MEK can attack many plastics and coatings. Always test compatibility before use on finished or polymer surfaces.
Does MEK require hazmat shipping?
MEK is regulated as a flammable liquid. Shipping requirements depend on package size, destination, and carrier rules.
