2-Hydroxyethyl Acrylate (HEA) Supplier in Malaysia
- Also known as
- HEA
- Hydroxyethyl Acrylate
- HEA Monomer
- 2-Hydroxyethyl 2-Propenoate
2-Hydroxyethyl acrylate supplier Malaysia for coating, adhesive and emulsion polymer buyers who order the hydroxy-functional monomer written on a specification sheet as HEA. It also trades as hydroxyethyl acrylate and 2 hydroxyethyl acrylate, under CAS 818-61-1 and formula C5H8O3.
Commercial 2-hydroxyethyl acrylate is a clear liquid supplied inhibited, usually with MEHQ, because an unstabilised acrylate polymerises with warmth and time. Offers separate on purity, water, free acidity, diacrylate content and the declared inhibitor level. No figure for any of those is published here; each one belongs to the documentation for the lot quoted.
The pendant hydroxyl is what buyers pay for: the acrylate double bond polymerises quickly, and the alcohol group survives to crosslink later with isocyanate, melamine or amino resins. That combination of fast cure and a reactive site puts it in UV and electron-beam curable coatings and inks, pressure-sensitive and structural adhesives, crosslinkable acrylic emulsions, automotive polyol resins, textile and leather finishes, and superabsorbent chemistry.
Send the limits your process holds, the inhibitor range if the recipe fixes one, the quantity and the delivery location with your enquiry. Pack format, documentation and timing are settled in the quotation. Supply is subject to applicable requirements.

2-Hydroxyethyl Acrylate 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 |
|---|---|---|---|---|
| Technical HEA monomer, standard inhibited | clear, colourless inhibited liquid | — | The routine reactor charge for crosslinkable acrylic emulsions, solution resins and pressure-sensitive adhesive polymers, carrying the customary MEHQ stabilisation. Suits plants running a settled recipe on a general monomer specification. | Drum or IBC formats are matched at quotation. |
| HEA supplied to a stated inhibitor range | clear, colourless inhibited liquid | — | For reactors whose recipe fixes the stabiliser level in ppm because it governs how the polymerisation initiates and how long an opened lot stays usable. Give the range the plant works to rather than leaving it unstated. | Drum or IBC formats are matched at quotation. |
| HEA to tighter water, acidity and diacrylate limits | clear liquid held to a low colour limit | — | Where residual moisture, free acidity or difunctional content would gel a copolymer, upset a urethane crosslinking step or shift the cure profile of a radiation-cured formulation. Send the limits your specification sets. | Drum or IBC formats are matched at quotation. |

2-Hydroxyethyl Acrylate applications
Safety and handling
Handle 2-hydroxyethyl acrylate as a reactive, polymerisable liquid. Keep drums closed, protected from heat and direct sun, and do not let the dissolved oxygen the inhibitor needs be displaced, since inhibitor depletion and warm storage are what start an unwanted polymerisation. The monomer can sensitise skin, so avoid contact and mists and work to the safety data issued for the lot quoted; treat storage temperature, shelf life and inhibitor level as items to confirm against that data. Supply is subject to applicable requirements.
Common questions about 2-hydroxyethyl acrylate
What is the difference between 2-hydroxyethyl acrylate and 2-hydroxyethyl methacrylate?
One methyl group separates them and it changes the chemistry. The acrylate reacts and cures faster and gives a softer, tougher polymer, while the methacrylate version cures more slowly and builds a harder, more rigid film. A recipe written for one is not run on the other, so order the monomer by name and give its CAS number.
Is 2-hydroxyethyl acrylate the same as acrylic acid?
No. This monomer is the hydroxyethyl ester, so it carries an alcohol group instead of a free carboxyl group, and the acid is its upstream feedstock rather than a substitute. The two are separate products on separate specifications; request each by name.
Why is HEA always supplied inhibited?
An acrylate monomer will polymerise on its own with warmth and time, so commercial material is stabilised, commonly with MEHQ. The declared level governs how the reaction starts in the reactor and how long an unopened lot remains workable, which is why polymer plants specify a range instead of accepting whatever arrives.
What does the hydroxyl group in HEA do in a formulation?
It stays intact through polymerisation and becomes a reactive site on the finished chain. Formulators use it to graft in crosslinking with isocyanates, melamine or amino resins, to raise adhesion to metal and treated substrates, and to build hydrophilicity into an otherwise water-repellent acrylic backbone.
Which HEA specification points belong in an enquiry?
Give purity, water content, free acidity and diacrylate content, the inhibitor type and range, the quantity and the delivery point. Mention the documentation the receiving plant needs so the quotation covers the whole requirement rather than the name alone.
How is a 2 hydroxyethyl acrylate price obtained in Malaysia?
Send the specification, inhibitor requirement, quantity and delivery location and the monomer is quoted on enquiry with a stated validity period. No list price is published, because a specialty monomer offer depends on grade, volume and pack format at the time of quoting.
