Diethylene Glycol (DEG) – High-Purity Industrial Solvent for Resins, Coolants & More

Diethylene Glycol (DEG) is a colorless, odorless, and hygroscopic organic compound widely used as a solvent, humectant, and chemical intermediate in multiple industrial processes. Known for its excellent solvency, high boiling point, and low volatility, DEG is ideal for applications in polyester resins, antifreeze formulations, plasticizers, and tobacco humectants.

At RealChemStore.org, we supply industrial-grade DEG with guaranteed purity (typically ≥ 99.5%) for manufacturers and distributors seeking bulk, cost-effective, and consistent chemical supply.

🏭 Primary Industrial Uses of Diethylene Glycol

✅ 1. Unsaturated Polyester Resins

Used as a reactive intermediate to enhance flexibility and water resistance in the production of polyester resins, coatings, and adhesives.

✅ 2. Heat Transfer Fluids & Coolants

DEG is a key ingredient in antifreeze and engine coolant formulations, owing to its low freezing point and ability to stabilize heat transfer systems in automotive and industrial equipment.

✅ 3. Plasticizers

Acts as a plasticizing agent in the manufacture of PVC, synthetic rubber, and polymer blends, improving flexibility and handling characteristics.

✅ 4. Tobacco & Ink Industries

Used as a humectant in tobacco products and printing inks to retain moisture and improve product longevity.

✅ 5. Cosmetic, Textile & Leather Industries

Functions as a softener, lubricant, or wetting agent in textile finishing, leather processing, and select cosmetic formulations (non-food grade only).
