Diethylene Glycol (DEG) is used in the coating industry for several important functions due to its solvent properties, ability to reduce viscosity, and role as an intermediate in resin production. Here are its key applications:
 
1. **Solvent for Water-Based Coatings:** DEG acts as a solvent in water-based coatings and paints, helping to dissolve resins and adjust the viscosity of formulations. Its miscibility with water improves the consistency and application of coatings.
 
 
3. **Plasticizer in Coatings:** As a plasticizer, DEG improves the flexibility and durability of coatings, reducing brittleness and enhancing the finish. It helps coatings withstand cracking and environmental stresses.
 
4. **Humectant in Paints:** DEG is used as a humectant in paint formulations to retain moisture, prevent premature drying during application, and improve flow properties for smoother finishes.
 
5. **Viscosity Reducer:** In formulations of high-solid coatings, DEG helps reduce viscosity, making it easier to apply coatings without sacrificing their performance or film thickness.
