Description

1, 2-propylene glycol diacetate is a colorless to light yellow liquid with low volatility and a slight sweet taste. It is soluble in organic solvents such as alcohols and ethers, but insoluble in water. PGDA is a functional environmentally friendly solvent with the general chemical properties of esters. Easy to dissolve in alcohol, ether and other organic solvents, with excellent leveling, low odor, safety and non-toxic, strong solubility, good bubble inhibition, strong dispersion of pigments. It has the advantages of anti-floating color, anti-white paint film, anti-heat rash, etc. It is an efficient, environmentally friendly and functional organic solvent.

Application

1,2-Propyleneglycol diacetate (PGDA) is a versatile solvent with a wide range of applications due to its favorable properties such as a high boiling point, low toxicity, and environmental friendliness. Here are some of the primary applications of PGDA:

Application Area	Use of PGDA	Function/Benefit
Ink and Adhesive	Replacement for various solvents in inks and adhesives	PGDA replaces isophorone 783, CAC, ethylene glycol monobutyl ether, propylene glycol ether ester solvents, cyclohexanone, diacetone alcohol (DAA), cresol, etc., due to its environmental safety and solvency.
Coating Film Additives	In can/coil coatings and as a film forming agent	Combines the properties of CAC, PMA, BCS, and CYC. Offers environmental friendliness, low odor, good leveling, and strong solubility. Enhances safety in storage and production due to high flash point. Improves gloss, fullness, and whiteness in topcoat paints. Prevents heat rash and dark bubble formation.
Water-based Curing Agents	As a diluent in water-based PU curing agents	Exhibits strong hydrophobicity and poor reactivity with NCO, enhancing fluidity and fullness of the film, and improves thickness of the non-foaming film.
Diluent for Various Resins	Replacing DBE as a solvent for multiple resins	Superior solubility compared to DBE. Effective in dissolving alkyd, acrylic, polyester, nitrocellulose, and chloro-acetate resins. Offers high boiling point, narrow distillation range, low-odor, and environmental protection.
Industrial Cleaning Agents	As a solvent in industrial cleaning	Effective in cleaning electronic and precision equipment
Pharmaceuticals	Solvent for active ingredients	Non-toxic and safe for use in sensitive applications
Cosmetics	In cosmetic formulations	Ensures safety and efficacy of cosmetic products
Food Industry	In flavor extracts and food additives	Safe for use in food-related applications
Resin Synthesis	For water-based resin synthesis	Enhances resin properties, useful in various industrial products
Electronics	In PCB circuit board ink and electronic ink	Improves print quality and durability on circuit boards
Cleaning and Paint Removal	Used as a cleaning agent and paint remover	Effective in removing paints and cleaning surfaces
Plastics Industry	Cellulose acetate plasticizer	Improves flexibility and durability of plastic products
Organic Synthesis	As an intermediate	Used in the synthesis of various organic compounds

The wide-ranging applications of PGDA in various industries underscore its importance as a solvent and an agent that enhances the performance of products in coatings, inks, adhesives, and more. Its growing popularity is also partly due to the increasing focus on environmentally friendly and safer chemical products in industrial processes.

Three Generations of High Boiling Point Environmental Solvent Comparison

Generation	Solvent Type	Key Characteristics	Applications
First	Organic Dibasic Acid Ester Mixtures	Can completely or partially replace solvents like cyclohexanone, ethylene glycol ether acetate, etc. Improves coating leveling and adjusts drying speed.	Used in steel, wood, container, food packaging, automobile coatings, enameled wire coatings, and baking paints.
Second	Ethylene Glycol Diacetate(EGDA)	More environmentally friendly than the first generation. Offers similar replacement functions for high-boiling point odor solvents.	Suitable for baking paint, nitrocellulose paint, coil steel paint, cellulose ester, fluorescent paint, iron printing paint, automotive paint, wood paint, insulation paint, and electrical appliances and metal furniture paint.
Third	1,2-Propylene Diacetate (PGDA)	Strong solubility, non-toxic, low odor, and more environmentally friendly than the first and second generations.	Ideal for alkyd resin, acrylic resin, polyester resin, nitrocotton resin, chlorinated resin, and PU curing agents. Functions as a superposition of the first two generations’ solvents.

Storge & Handling

Stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and incompatible materials. It is important to keep the container tightly closed when not in use.
