Propylene glycol diacetate, as a high boiling point slow-drying environmentally friendly solvent, can dissolve acrylic, PU, epoxy, alkyd, and nitro resins;
– Automotive paint, coil paint, canning paint, industrial baking paint: improves paint film flatness, gloss and fullness, reduces pinholes, orange peel, and shrinkage;
– Film-forming additives in water-based paints; can replace cyclohexanone, isopropylpyrolidone, DBE, PMA and other high VOC traditional solvents.
2. Ink Industry (Popular)
– PCB circuit board solder mask ink, screen printing ink, gravure ink;
– High purity, low metal ions, suitable for electronic ink formulation.
3. Adhesive
– Water-based PU curing agent thinner， epoxy glue， water-based adhesive solvent； improves wetting property， prolongs curing time.
4. Industrial Cleaning
Propylene glycol diacetate is used in electronic components and precision hardware cleaning agents； dissolves resin residues， oil stains， and old paint films； has low corrosiveness to metal substrates， and low residue after cleaning.
5. Casting Industry
Water glass sand organic ester curing agent (classic application)， 1，2-Propyleneglycol diacetate is used for casting steel / cast iron molding， controls curing speed.
✨ Product Selling Points

FAQ
Q: Packaging specifications, MOQ?
A: Regular bulk shipment: 220kg / plastic barrel / iron barrel; also available in IBC ton barrel. MOQ: 220kg. Samples: 100ml, 500ml, 1L glass bottles.
Q: Storage conditions and shelf life?
A: Store in a sealed, cool, ventilated warehouse, away from open flames, heat sources, and strong oxidants; original sealed barrels have a shelf life of 12 months.
Q: Flashpoint? Volatility rate like?
A: Closed cup flashpoint 87℃; it is a slow-drying solvent, with a gradual evaporation rate, which helps to level the paint film and reduce orange peel and pinholes.
Q: Differences between PGDA and PMA, DBE?
A: PGDA has excellent solubility and lower odor; its evaporation rate is between PMA and DBE; it is a dedicated curing agent in the casting industry, and PMA/DBE cannot replace it.
Q: Does it dissolve in water?
A: It can partially dissolve in water, and is completely miscible with organic solvents such as alcohols, ketones, and esters.
Q: Can samples be arranged for international express delivery?
A: Yes, for regular samples; provide SDS, packing list, invoice. The sample shipping cost is borne by the customer.
Q: Delivery time for bulk goods?
A: Samples: 3-5 working days after receiving the shipping fee; bulk goods: after the deposit, 7-12 working days, with stock available, it can be shortened to 3-5 days.
