Coolants and Antifreeze
A functional fluid, propylene glycol Industrial Grade (PGI) serves in aircraft deicing and anti-icing fluids, antifreeze, engine coolants, heat transfer fluids offering benefits including:

Biodegradability Excellent heat transfer properties   Low freezing point   The ability to decrease the freezing point of water   Low flammability   A high boiling point, low vapor pressure

Paint and Coatings
Water-based architectural coatings incorporate propylene glycol because it is fully miscible with water and improves application properties by adjusting drying time and aiding in the freeze/thaw characteristics.

Liquid Detergents
Propylene glycol serves as a solvent, enzyme stabilizer clarifying agent and diluent in liquid detergents.
