PRODUCTS
Propylene Glycol Monomethyl Ether Acetate a slow evaporating solvent with both ether and ester functional groups. It is a colorless liquid with a mild odor. Propylene Glycol Monomethyl Ether Acetate Acetate is an excellent solvent for many commonly used coating polymers, including cellulose acetate butyrate, nitrocellulose, epoxy resins, acrylic copolymers, and phenoxy resins.
The combination of slow evaporation rate and good solvent activity makes Propylene Glycol Monomethyl Ether Acetate an effective retarder solvent for use in lacquers, thinners, and baking enamels. It is supplied as a urethane grade solvent.
PMAc should be stored only in tightly closed, properly vented containers away from heat, sparks, open flame or strong oxidizing agents. Use only non-sparking tools. Containers should be grounded before beginning transfer. Electrical equipment should conform to national electric code. Handle empty containers carefully. Flammable combustible residue remains after emptying. Storage in properly lined steel or stainless steel to avoid slight discoloration from mild steel is recommended. Avoid contact with air when storing for long periods of time. This product may absorb water if exposed to air.

Propylene glycol methyl ether acetate (PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether used in inks, coatings,
and cleaners.
In the semiconductor industry, PGMEA is a widely used solvent, mainly for the application of surface adhesives on silicon
wafers. The compound is the most abundant and used product in semiconductor cleanrooms, mostly in air, as it evaporates
into ambient air.
Ultra-high-purity propylene glycol monomethyl ether acetate (PGMEA) is required as a solvent to meet the stringent
requirements of the electronic-grade semiconductor industry.
PGMEA is glycol ethers based on propylene oxide. This is solvents having a bi-functional nature (ether-alcohol and the
respective acetate). They are both clear liquids, with PGMEA having a pleasant, fruity odour.
They are used as intermediates and in formulations in industrial, professional or consumer applications, mainly in surface
coatings, printing inks, cleaners, agrochemical or deicing/anti-icing formulations. They are also used as extractants, and as
coalescing agents and flow improvers in water-based paints.
These glycol ethers are transported by marine, road and rail, primarily in bulk quantities, but also as packed products. Due to
their flammability, they are classified as hazardous for transport under transport regulations. Glycol ethers should be stored
at ambient temperatures away from sources of ignition and substances with oxidising or corrosive properties. Propylene
Glycol Monomethyl Ether Acetate is stabilised with a certain amount of inhibitor to prevent the formation of peroxides.
Propylene glycol monomethyl ether acetate Usage
The utility model relates to a non-public hazard solvent with multiple functional groups.
Mainly used in ink, paint, ink, textile dyes, textile oil solvent, can also be used in the production of liquid crystal display cleaning agent.
Used as a solvent for paints, inks, lacquers, varnishes, cleaners, coatings, ink-removers, and pesticides. Used in photoresist formulations in the semiconductor industry; Also used in solvents for degreasing circuit boards and in food contact applications.
Metal Degreasing
More than 400 million pounds of halogenated hydrocarbons were used in that year. In response to scientific knowledge and governmental regulations, alternate degreasing processes have been developed since the 1970s. D-Limonene has been used as a substitute, and new semiaqueous processes have been installed to reduce exposures in the workplace and pollution of the environment.
Painting (Solvents)
Types of organic chemicals used as paint solvents include aromatic, aliphatic, glycol ethers, chlorinated solvents, terpenes, alcohols, acetates, and ketones. Significant exposure can occur in spray painting and in brushing or Rolling.
Silk-Screen Printing
Silk-screen printing may expose workers to cadmium, chromate, lead, and manganese pigments; also to solvents (Stoddard, toluene, xylene, and ketones). In traditional silk-screen printing, the craftsperson applies the stencil with a brush. The ink is squeezed through the screen to transfer the image. Modern silk-screen printing uses nylon, Dacron, or polyester mesh for the screen and stencils are made with computer software. Designs and lettering for decals, posters, wallpaper, bottles, clothing, and printed circuit boards are commonly produced in this way. UV-cured inks based on acrylates and methacrylates are now the usual method of producing silk-screen images. Screen-printing in the electronics industry exposes workers to the skin
sensitizers 4,4′-diaminodiphenylmethane, triglycidyl isocyanurate, and 2-hydroxyethyl methacrylate. Some silk-screen printers are exposed to 2-alkoxyethanols and acetates. Other potential exposures to methyl alcohol, ethyl alcohol, and isopropyl alcohol; Ammonium dichromate and carbon arcs used with photo stencils; Carbon arc fumes may contain rare earth metals

Propylene glycol monomethyl ether and acetic acid are taken as raw materials to carry out esterification reaction in the presence of a supported catalyst; water generated in reaction is removed through azeotropic distillation, and a product generated after reaction is rectified into PMA, wherein the catalyst has uniform molecular-size ducts, ion exchange property, acid catalysis activity and good thermal stability and hydrothermal stability. The production can realize one-stage continuous
production of PMA, is simple in operating mode, is capable of obviously improving the production efficiency of PMA, reducing
the production cost of PMA, reducing discharge of solid pollutants and wastewater.
The reaction product does not need to be neutralized by plenty of alkali. The catalyst has long service life. The production
method has terrific large-scale industrial application value.
The invention relates to a process for synthesizing propylene glycol monomethyl ether acetate, which comprises subjecting propylene glycol methyl ether, acetic acid and toluene to esterification reaction at the presence of methyl benzene sulfonic acid catalyst, then reclaiming the excess propylene glycol methyl ether with dealkylation tower and rectifying, thus obtaining propylene glycol methyl ether acetic ester.
