Methacrylic Acid (MAA) Supplier in Malaysia
- Also known as
- MAA
- 2-Methylpropenoic Acid
- 2-Methyl-2-Propenoic Acid
- Alpha-Methacrylic Acid
Methacrylic acid supplier Malaysia for polymer, coatings, admixture and resin manufacturers who buy the acid monomer itself. Shortened to MAA in the trade and written as 2-methylpropenoic acid on a specification sheet, it carries CAS 79-41-4 and formula C4H6O2. It is a different monomer from acrylic acid and it is not methyl methacrylate.
Enquiries normally name glacial methacrylic acid, an inhibited grade with a stated inhibitor type and level, or an aqueous solution at a given strength. Glacial is the concentrated liquid form and covers most copolymer work. A dilute strength is quoted only when the recipe calls for the acid already diluted.
Formulators specify methacrylic acid where a copolymer needs harder carboxylated segments along with alkali solubility, adhesion and better pigment dispersion. That puts it in emulsion binders, pressure-sensitive adhesives, ion-exchange resins, polycarboxylate concrete admixtures, dispersant and superabsorbent polymers, and paper, textile and leather treatment polymers.
Send the grade, assay target, inhibitor requirement, quantity and delivery location with your enquiry. Availability, pack format, documentation and timing are settled at quotation. Supply is subject to applicable requirements.

Methacrylic Acid grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Glacial methacrylic acid | clear, concentrated liquid monomer | commercial glacial material typically runs 99% and above | The usual traded form for acrylic copolymer, ion-exchange resin and admixture polymer synthesis where the reactor takes a concentrated acid charge. State the assay target and any impurity limits that matter to the process. | Drum, IBC or bulk options are matched to the quantity at quotation. |
| Inhibited methacrylic acid | clear liquid monomer carrying a polymerisation inhibitor | — | Commercial supply for plants whose storage life and reaction start are validated against a declared inhibitor type and level. Name the inhibitor the process runs on instead of accepting whatever is standard. | Drum, IBC or bulk options are matched to the quantity at quotation. |
| Aqueous methacrylic acid solution | diluted aqueous solution | — | For formulation routes that charge the acid already diluted, so the water forms part of the recipe. Give the strength you need, since dilution is made to the requirement rather than held as one standard concentration. | — |

Methacrylic Acid applications
Safety and handling
Methacrylic acid is a polymerisable acid, corrosive to skin and eyes, that crystallises in cool conditions. Keep containers closed in a well-ventilated place away from heat, ignition sources and incompatible materials, and follow the safety data issued for the quoted grade. Treat storage temperature, shelf life and inhibitor level as items to confirm rather than fixed figures. Supply is subject to applicable requirements.
Common questions about methacrylic acid
What is glacial methacrylic acid?
Glacial is the concentrated liquid monomer rather than a diluted aqueous solution, and it is the form most copolymer and resin work charges. Buyers who specify glacial methacrylic acid are usually after high assay material, so send the assay target and quantity with the enquiry.
What is the difference between methacrylic acid and acrylic acid?
They are two different monomers. Methacrylic acid carries an extra methyl group on the double bond and sits under CAS 79-41-4, while acrylic acid is CAS 79-10-7 and has its own page. Copolymers built on the methacrylic version run harder and hold up better to hydrolysis, so order each acid by name.
Is methacrylic acid the same as methyl methacrylate?
No. Methyl methacrylate is the methyl ester of this acid and a separate product with its own specification and page. Both get shortened in conversation, so write methacrylic acid or methyl methacrylate in full on the order.
Why is methacrylic acid supplied inhibited?
An inhibitor is added so the monomer does not start polymerising in storage or while it is being dosed. The type and declared level should match what the reactor is validated on, and both are confirmed for the grade quoted.
Does methacrylic acid solidify in the container?
It can. The acid crystallises near ambient temperature, so material held in a cool store may arrive part solid and need controlled warming and remixing before use. Handle that to the supplier instruction for the quoted grade.
How do I get a methacrylic acid price in Malaysia?
Send the grade, assay target, inhibitor requirement, quantity and delivery location. Methacrylic acid is quoted on enquiry with a stated validity period rather than carried as a published list price.
