Methyl Methacrylate (CAS 80-62-6) is a colorless, volatile methacrylate monomer supplied in Technical Grade that serves as the primary building block for PMMA acrylic glass and high-performance resins and as a hard monomer in copolymer systems for coatings, acrylic sheets, impact modifiers and dental materials. Supplied in Technical Grade with 99.9% Purity, it is inhibited to ensure safe transport and storage.
This colorless, volatile liquid is valued for its ability to create polymers with exceptional Optical Clarity, weatherability, and scratch resistance. It acts as a hard monomer in copolymer systems, significantly increasing the mechanical strength of the final product.
In industrial applications, MMA is a key ingredient in the manufacture of surface coatings, acrylic sheets, and impact modifiers. Its Fast Curing properties make it a staple in advanced automotive paints and dental restorative materials.
