Application Fields of Propylene Glycol Diacetate(PGDA)

Propylene glycol diacetate(CAS No.627-82-7),also known as 1,2-propanediol diacetate or PGDA,is a colorless,odorless ester derived from propylene glycol and acetic acid.It is valued for its excellent solvency,low volatility,and favorable environmental and safety profiles.Below are its primary application areas across industries:

1.Paints,Coatings,and Inks

Solvent and Coalescing Agent:

Widely used in water-based and solvent-based paint/coating formulations(e.g.,acrylic,epoxy,and polyurethane systems)to dissolve resins and improve film formation.

Acts as a coalescing agent,enhancing the fusion of polymer particles in latex paints to form smooth,crack-free coatings with improved adhesion.

Printing Inks:

Used in flexographic,gravure,and offset inks for packaging(e.g.,plastics,paper),where its low odor and slow evaporation ensure consistent ink transfer and drying properties.

2.Textile and Leather Processing

Dyeing and Finishing:

Solubilizes disperse dyes in textile dyeing processes,particularly for synthetic fibers(e.g.,polyester,nylon),ensuring uniform color penetration and fastness.

Leather Tanning and Coating:

Enhances the compatibility of tanning agents(e.g.,vegetable tannins,synthetic resins)with leather fibers,improving softness and water resistance.

Used in leather coatings to dissolve polymers and pigments,providing a smooth,glossy finish.

3.Plastics and Polymer Industry

Plasticizers and Additives:

Acts as a temporary plasticizer in PVC and polyolefin processing,reducing melt viscosity during extrusion or injection molding while maintaining product flexibility.

Improves the processability of hot-melt adhesives and sealants by adjusting curing rates and bond strength.

Reactive Diluents:

Dilutes high-viscosity resins(e.g.,epoxy resins)in composite materials,adhesives,and coatings,reducing application viscosity without compromising mechanical properties.

4.Pharmaceuticals and Cosmetics

Pharmaceutical Solvents:

Used as a non-toxic solvent or co-solvent in oral medications,topical creams,and inhalants due to its low toxicity and compatibility with active pharmaceutical ingredients(APIs).

Cosmetic Formulations:

Incorporates into perfumes,lotions,and hair care products as a fragrance solubilizer and emollient,enhancing product stability and skin feel.

5.Agricultural Chemicals

Pesticide and Herbicide Formulations:

Solubilizes lipophilic active ingredients(e.g.,pyrethroids,triazines)in emulsifiable concentrates(ECs)and microencapsulated formulations,ensuring uniform dispersion in water.

Fertilizer Additives:

Improves the miscibility of liquid fertilizers with water,reducing sedimentation and enhancing nutrient absorption by plants.

6.Electronics and Semiconductor Manufacturing

Cleaning Solvent:

Used in precision cleaning of electronic components(e.g.,PCBs,sensors)to remove flux residues,oils,and particulate contaminants,meeting strict purity requirements for semiconductor fabrication.

Solvent for Conductive Pastes:

Dissolves metal nanoparticles(e.g.,silver,copper)in conductive inks for printed electronics,such as flexible circuits and touch screens.

7.Industrial Cleaning and Degreasing

Specialty Cleaners:

Formulated into industrial degreasers and precision cleaners for metalworking,aerospace,and automotive industries,effectively removing grease,oils,and waxes from surfaces without leaving residues.

Adhesive Removers:

Used in formulations to dissolve cured adhesives(e.g.,epoxy,acrylic)during repair or rework processes.

8.Food and Flavor Industry

Food Additives:

Approved as a food-grade solvent and flavor carrier(e.g.,in artificial flavors,essences)under regulatory standards(e.g.,FDA,EFSA),due to its GRAS(Generally Recognized As Safe)status.

9.Renewable Energy and Battery Production

Lithium-Ion Battery Manufacturing:

Explored as a co-solvent in electrolyte formulations to improve ion conductivity and compatibility with lithium salts,though less common than glycol ethers.

Key Properties Enabling Its Use:

Low Toxicity:Generally considered safe for industrial and consumer applications(always follow SDS guidelines).

High Boiling Point(~230°C):Suitable for high-temperature processes with minimal evaporation.

Good Solvency:Dissolves a wide range of resins,polymers,and organic compounds.

Environmental Friendliness:Biodegradable and low in volatile organic compounds(VOCs),aligning with green chemistry standards.

Safety and Handling:PGDA is non-flammable and has low skin/eye irritation potential,but proper ventilation and PPE(gloves,goggles)are recommended for prolonged industrial use.Store in cool,dry conditions away from strong oxidizers.
