DPM (DPGME) Dipropylene Glycol Monomethyl Ether dipropyl ether is a high-performance, environmentally friendly medium-speed evaporation solvent. It's equipped.Excellent solubility and chemical stability, in colourless, transparent liquid form, with a slight odour of ether. As a result of its molecular structure, it has been equipped with both aqueous and aluminum cells, making it an ideal medium for connecting water and oil systems.It is widely used in paints, inks, detergents and semiconductors and electrochemicals.

Solvability
The DPM is a water- and oil-friendly one-size-fits-all solvent with a special molecular structure that makes it highly effective in both water and solvent systems.
Advantages
Medium evaporation rate
The DPM is pacing (with a evaporation rate of approximately 0.03) and provides sufficient flow time in paint applications to ensure that the paint membrane is flat and fine, while avoiding needle or bubble problems due to over-drying.
Extreme dissolution efficiency
The KB value (Kauri-Butanol value) enables it to achieve the desired dilution at a lower level, helping to improve the formula cost.
Low odor and low toxicity
- Compared to traditional ethanol ethers, the DPMs have a lighter and less toxic odour, which greatly improves the comfort of the construction environment and is in line with modern-day green chemistry.
Security
- High-flash, non-flammable: the flash point of the DPM is 75°C, which does not include flammable liquid management in most countries, reducing fire safety risks and costs in production, storage and transport.
Strong compatibility.
- Bridge function: Because of its well-prepared relative oil and water balance (HLB), it is a perfect adhesive connection between water and solute resin and an indispensable co- solubility in the transition water product.
- Reduced surface tension: can increase the humidity of paint or detergents to the base and make the product more evenly attached to plastic, metal or wood surfaces.
Use Help
Semiconductor and electrical industries
- Photoresist Strippers: DPM is the core solvent in the excavator formulation during the crystal circle process or the PCB process.
- Electronic Cleaning: DPMs are used to remove pollutants from the manufacturing process, with low surface tension that allows them to penetrate tiny circuit cracks (e.g. under BGA seals), and to clean out hard-to-reach areas, such as welders, cedars and grease.
- Post-Etch Resaidue Removal: After the electrocution process, the surface leaves an extremely difficult to remove polymer residue (Tiw/Al by-product).
- Electropults and electric inks (Conduitive Pastes & Electronic Inks): When wiring electronic components (e.g. sensors, soft circuit boards)
- Sticky tunes: DPMs are used to adjust the viscosity of the plute, such as silver and carbon, to ensure the accuracy and continuity of the print circuit.
- Control of open time: prevent slurry from drying up on the net and increase production continuity.
- LCD: In the manufacture of the LCD panel, DPM is used as a detergent or formulation solvent to assist in dispersing paint and maintaining the membrane balance.
General industrial use
- Water coating: as an aphrodisiac, improves the stability of the lactation system and provides excellent fluency during the drying process, and prevents the fragmentation of the paint sheet turtle.
- Wooders and metal paints: Effectively dissolved acrylic acids, ethanolic acids and epoxy resins, and increased radiance and adjunct of the paints.
- Spray application: due to a steady evaporation rate, this prevents the dry-spraying of the process and makes the coating more even.
- Ribbon printing: preventing ink from drying up the Internet and blocking the hole while ensuring quality of the material that is printed on the base.
- Water ink: Balancing the ink's viscosity, increasing the stability of colour paints and their brightness.
- Heavy defamination: oils and waxes on engines, parts of machinery that can quickly penetrate and decompose.
- Hard surface cleaning: the cleaning agent used on the glass, floor and metal surfaces without leaving any residue.
- Depasers and detaches: as a valid ingredient, remove old coatings or photoresisting.
Security & Save Proposal
Save Conditions
- A cool, cold, cold, cold, cold, dry and well-ventilated warehouse. It's not like we're going to be able to use the sun and fire.
- Sealed storage: DPM is humid and, when opened, secure the container to prevent the absorption of water in the air from affecting purity and performance.
- Ban on substances: Should be isolated from stronger oxidants (e.g. peroxide, nitrate) to avoid chemical reactions.
- Ground design: The storage area is advised to have a fence or loss-proofing facility to prevent accidental leakage into the drainage system.
Operation Environment and Operational Advice
- Personal protection (PPE): Please wear protective glasses, chemical gloves (recommended to use butler or butyl rubber) and work clothes.
- Gas protection: DPM is less active, but it is recommended to wear appropriate respiratory protections in poorly ventilated closed spaces.
- Cleaning measures: If the skin is accidentally touched, wash with plenty of water and soap, and if you enter your eyes, wash with water for more than 15 minutes and be treated.
Transport Recommendations
- Unrestricted goods: As the flashpoint of the DPM is about 75°C (up to the normal 60.5°C Flammability limit), in many international and domestic transport laws (e.g. IMDG, IATA), the DPM is not usually listed as "flammable liquid" dangerous at constant temperatures.
- High safety: Compared to low-flicker solvents such as methazene or acetone, DPM has fewer transport restrictions and can effectively reduce logistics costs.
