Propylene Glycol Methyl Ether (PGME) Supplier in Malaysia
- Also known as
- Propylene Glycol Monomethyl Ether
- PGME
- 1-Methoxy-2-Propanol
- Methoxypropanol
Propylene glycol methyl ether supplier in Malaysia for coating, printing ink, cleaning and electronics formulators. It is also written propylene glycol monomethyl ether and shortened to PGME, while specification sheets often print 1-methoxy-2-propanol or methoxypropanol. CAS 107-98-2, formula C4H10O2.
The liquid mixes with water in all proportions and still dissolves resins and oily residues, which is the property it is bought for. It is the fast one in the P-series range, releasing from a wet film well before the dipropylene ethers do. Commercial choice runs from industrial and technical grade to low-water material and electronic grade with metal-ion limits.
Coating plants use it as an active and coupling solvent, ink makers for solvency and flow, and electronics lines for precision cleaning and photoresist-related steps. Further demand sits in hard-surface cleaner concentrates, brake and hydraulic fluids, adhesives, agrochemical concentrates and textile processing.
This page covers the alcohol, not the acetate ester: propylene glycol methyl ether acetate is a separate product with its own page. The dipropylene homologue and propylene glycol itself are separate again. Send the grade, target specification, quantity and delivery location with your enquiry.

Propylene Glycol Methyl Ether 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 |
|---|---|---|---|---|
| Industrial and technical grade propylene glycol methyl ether | clear, colourless liquid | — | Active and coupling solvent for lacquers, varnishes, wood and industrial coatings, printing inks, adhesives and general fast-release solvent duty. | Drum, IBC or bulk formats are confirmed with the quotation. |
| Low-water grade propylene glycol methyl ether | clear, colourless liquid | — | Moisture-sensitive chemistry such as isocyanate-containing systems, brake and hydraulic fluid blending and reactions where dissolved water shortens pot life or shifts a titration. | Sealed drum or IBC options are confirmed with the quotation. |
| Electronic grade propylene glycol methyl ether | clear, colourless liquid | — | Precision cleaning, rinsing and photoresist-related processing in electronics manufacturing, where metal-ion, particle and water limits are written into the purchasing specification. | Pack format for high-purity material is confirmed with the quotation. |

Propylene Glycol Methyl Ether applications
Safety and handling
Keep the container closed in a cool, well-ventilated store away from heat, ignition sources and strong oxidisers. It is a hygroscopic solvent, so an opened drum picks up moisture and a low-water grade should be resealed promptly. Follow the safety information issued for the grade quoted. Supply is subject to applicable requirements.
Common questions about propylene glycol methyl ether
What other names is propylene glycol methyl ether sold under?
Buyers specify it as propylene glycol monomethyl ether, PGME, 1-methoxy-2-propanol, methoxypropanol or 2-methoxy-1-methylethanol, and CAS 107-98-2 settles the identity. Quote the name printed on your own specification with the enquiry so the correct material is matched before pricing.
Is propylene glycol methyl ether the same as propylene glycol methyl ether acetate?
No. The acetate is the ester made by acetylating this alcohol, and it is a different product with its own CAS number, its own page and a slower evaporation profile. Order the acetate by name if the coating or photoresist formulation specifies the ester.
What is the difference between propylene glycol methyl ether and the dipropylene version?
They are separate molecules from the same family. The mono product on this page is the fast one, used where the solvent has to leave the film quickly, while the dipropylene ether carries a second propylene unit and evaporates far more slowly as a coalescent. Order each by name.
Is propylene glycol methyl ether the same as propylene glycol?
No. Propylene glycol is the plain diol and is a different substance with its own page and specification, while this material is the methyl ether of that glycol and behaves as an industrial solvent rather than a humectant or carrier.
Which grade should be requested for a coating, cleaner or electronics duty?
Industrial and technical grade covers coatings, inks, adhesives and general cleaner formulation. Low-water grade suits moisture-sensitive blending such as isocyanate chemistry and brake fluid work. Electronic grade is selected where metal-ion, particle and water limits are specified for precision cleaning or photoresist processing.
Why do formulators choose this solvent over a hydrocarbon or an alcohol?
It mixes with water in all proportions yet still dissolves resins, oils and polar residues, so one solvent can couple a water-based system and clean an oily surface. The fast evaporation rate also releases from a film early, which hydrocarbon solvents of similar strength do not always match.
What information is needed for a propylene glycol methyl ether price enquiry?
Send the grade, application, any purity or water-content limits, the quantity and the delivery location. Note the documents you need and the timing you are planning around so the quotation answers the whole requirement in one pass.
