Product Overview
Evonik MMA (VISIOMER® MMA) is a clear, colorless methacrylate liquid with an assay of at least 99.9%.
With the molecular formula C5H8O2 and a molar mass of 100.12 g/mol, methyl methacrylate polymerizes through bulk, suspension, emulsion and solution routes. Its low acid and water content support predictable reaction behavior and clear finished polymers.
The monomer is a building block for poly(methyl methacrylate), acrylic resins, impact modifiers and reactive diluents. It is also the starting material for other methacrylate esters used across coatings, plastics and dental materials.

04 / Quality
Grade Consistency
Four measurable limits define what a processing line can expect from Evonik MMA 99.9% from one lot to the next.
Assay by gas chromatography, giving a high-purity monomer for clear PMMA sheet and acrylic resins.
Pt-Co colour value, helping finished sheets, lenses and coatings stay free of yellow cast.
Methacrylic acid content, limiting side reactions during free-radical polymerization.
Water content measured by Karl Fischer, supporting stable batch behavior in storage.

About the Company
Ascent Group Co., Ltd supplies Evonik MMA and the Evonik VISIOMER methacrylate range to formulators working with acrylic resins, coatings, adhesives and PMMA.
Product quality starts with the specification itself: an assay of at least 99.9%, methacrylic acid held to ≤0.0050% and water to ≤0.050%. Those limits define what a processing line can expect from lot to lot, and they are the reference point for incoming checks.
Technical data, safety data and batch documents can be supplied for review. Inhibitor options including MEHQ, HQ, BHT and DMBP can be matched to the customer's downstream process and storage conditions.
Methyl methacrylate is classified as a flammable liquid, UN 1247, Class 3. Handling guidance therefore covers inhibitor selection, storage below 30 °C, protection from heat and UV light, and the six-month shelf life stated in the product specification.
Packaging is offered in 190 kg net steel drums, with dispatch terms arranged around the buyer's production schedule and receiving facilities.
