1. Product Introduction & Main Application
Arnico’s Methyl Acetate 99% is a clear, colorless, fast-evaporating organic ester with a mild fruity odor, used as an environmentally friendly, non-toxic (non-HAP) solvent in the paint, ink, adhesive, and industrial cleaner industries. Due to its VOC-exempt status in many regions, this volatile, high-solvency solvent is an ideal replacement for Methyl Ethyl Ketone (MEK) and Ethyl Acetate.
