Description

Application
It is widely used in the production of acrylic resins plastics adhesives coatings and ion-exchange resins. It also serves as a key raw material in the manufacture of polymethacrylates and other specialty polymers.

Purpose
The main purpose of methacrylic acid is to act as a monomer for polymerization enabling the formation of durable transparent and weather-resistant materials used in a wide range of industrial and commercial products.

General Description
Methacrylic acid (stabilized with MEHQ) is a colorless corrosive liquid with a sharp odor containing a vinyl functional group and a carboxylic acid group. It is typically inhibited with MEHQ (monomethyl ether hydroquinone) to prevent premature polymerization during storage and handling.
