What are the uses of propylene glycol?

1. Propylene glycol is an important raw material for the production of formaldehyde-free epoxy resin, epoxy resin, polyurethane resin, plasticizer and surfactant.

2. Used as plasticizer and ink additive for alkyd resin.

3. It has excellent bactericidal properties and moisturizing properties, and can be miscible with a variety of substances. It is a solvent for grease, paraffin, resin, dye, etc. It is used as a drying moisturizer and dissolving agent in high-grade liquid repellents.

4. In the coating industry, propylene glycol has the characteristics of low freezing point and can be mixed with water. When mixed with water, it can greatly reduce the freezing point of the overall coating and enhance the anti-freeze performance of the coating, so it is often used as an antifreeze in coatings. , which can prevent the paint from freezing at 0 degrees. Due to its good compatibility with water and other solvents and its high boiling point, it can easily reach equilibrium in water-based coating systems. It can also provide fluidity to the coating and slow drying of the coating.

5. Antifreeze for aircraft.

6. In the food industry, propylene glycol is used as a trace solvent for various spices, pigments, and preservatives.

7. Starting moisturizer for tobacco industry.
