Propylene Glycol Industrial Grade is a colorless, odorless and slightly viscous liquid. Because of its versatility propylene glycol is used in a variety of applications in aqueous solutions and over a wide temperature range.PGI 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.
