PGM is also known as PGME (Propylene Glycol Monomethyl Ether) as a non-colorable, transparent, high-quality Ether type solvent, which smells of light ether, and which is often used as a high-performance, low-toxicity, environmental-type solution with its core competitive advantage in its unique molecular structure. It's also equipped with "ether key" and "synthesis" so that it can show a good relationship between water and oily systems. PMA As a common formula.
PM is widely used in electronics, coating and cleaning, with a scalding point (approximately 119°C), which has a good solubility, is fully soluble with water and most organic solvents, is mild, does not create irritant vapours, and is suitable for the precise formulation. The company.Electro-grade PGME (PM) Metal ion to PPB level with extremely low waterIt's common in industrySemi-conductor photoretardants, display panel paints, oil diluents and metal washing agentsIt is also important to improve production stability and product quality.

Solvability
PM solvents have a strong dilution and solubility, and are able to solute in an arbitrary proportion with water and multiple organic solvents. (b) Natural matter: dyes, grease, wax and natural glue.
Advantages
Accurate evaporation rate and current level performance
The solubility of PMs in paint and printing ink applications is not only now "dissolved" but also equal to evaporation rates. This helps to improve the system's viscosity control, prolongs the open time and provides excellent membrane functions during the drying process, ensuring that the coating surface is flat and impervious.
Best medium for a water system.
As environmental regulations evolve, PM becomes an indispensable "coupling agent" in the water-painting system. It is effective in stabilizing polymer particles in water-based formulations, preventing separation and increasing the chromosomal power and dispersing stability of water-based chromium.

Electronics and semi-conductor industries
- Photoresist dilution and removal: PM is the main solvent in the photoresist formulation, which is used to adjust adhesiveness, to ensure that photoresistance is plastered on the crystals, to improve evenity and visibility, to ensure sharpness on the edges of the pattern after exposure, and to improve the probabilities and resolution limits of the whole system. It is also used for exposure and edge removal (EBR).
- Electro-component cleaning: It has an excellent ability to decontaminate and effectively remove welding, grease and fingerprints from the electrical circuit boards (PCB) during their assembly.
- LCD: A coating solution for Color Filter to ensure an equal colour thickness.
- Semi-conductor sealing: Diluent diluent as epoxy resin sealing material during the containment process to assist in the flow of materials and to reduce bubble production.
- Crystal Circle Cleaning: Clear the edges and ensure the cleaning and virtuousness of the elements.
- RRC/EBR Program: Steady Cleaning and Removal to Support Advance Node Production.
General industrial use
- High performance coating and paint: as a membrane assistor to increase fluidity and radiance of the coating. Carrying a dosage in aqueous paint to prevent layering or corrosion during storage.
- Print ink: Especially for silk and soft-copy printing, the appropriate evaporation rate prevents the ink from drying up on the ink and at the same time ensures that the print is fast solidified. Increases the color density and dispersing stability of ink.
- Industrial cleaning agents: These should be used in metal defamining, depainting and hard surface cleaning formulations, especially for environments where there is a need for "low flash safety risks".
- Weeding and leather processing: As a carrying solvent of dyes, ensure that the dyes are nuanced to the chromosomal effect.
- Agricultural chemicals: use as a solvent or emulsifier in agropharmaceutical formulations to improve the propagation and absorption of pharmaceutical products.
Security & Save Proposal
Save Condition
- It's cool, dry, well ventilated, away from the heat, sunlight, and non-compatible matter, such as strong oxide.
- Sealed in iron, soft steel or americium containers to avoid plastic containers and keep room temperature below 30°C
- The storage area needs to be clearly marked, limited and equipped with leak detection and fire protection equipment
Operation Environment
- Operate in a good ventilation area to avoid the generation of fog or steam, with protective equipment and distance from the open fire
- Stop smoking, keep the containers closed, separate the work area from the storage area and avoid low-lying areas.
