Propylene Glycols

Propylene Glycol Industrial Grade (PGI)

Propylene Glycol Industrial Grade (PGI) from Dow is an important intermediate in the production of alkyd resins for paints and varnishes. It is the preferred propylene glycol for manufacturing high-performance, unsaturated polyester resins for many uses such as:

• Reinforced plastic laminates for marine construction
• Gel coats
• Sheet molding compounds (SMC)
• Synthetic marble castings

Propylene glycol is also used as a solvent in printing inks, as a preservative in floral arrangements, and as a stabilizer in hydraulic fluids.

PGI is available from Dow in drum and bulk quantities.

Applications

Unsaturated Polyester Resins
Urethanes
Coolants and Antifreeze
Aircraft Deicing Fluid
Hydraulic and Brake Fluid
Heat Transfer Fluids
Paint and Coatings
