Product Description

Eastman™ MAK (Methyl n-Amyl Ketone) has a high solvent activity, slow evaporation rate, low density, low surface tension, and high boiling point. These properties make MAK a very good solvent for cellulosic lacquers, acrylic lacquers, and high-solids coatings. Because regulations limit the weight of solvent per gallon of coating, formulators favor the use of low-density solvents that help reduce the VOC content of a coating. MAK is lower in density than ester, aromatic hydrocarbons, and glycol ether solvents with similar evaporation rates. The low density and high activity of MAK are significant advantages when formulating high-solids coatings to meet VOC guidelines. MAK is also used as a polymerization solvent for high solids acrylic resins.

The chemical substances for this product are listed as Inert Ingredients Permitted for Use in Nonfood Use Pesticide Products, and in Food Use Pesticide Products with limitations, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
