Used primarily as a plasticizer in polymer formulations, this compound enhances flexibility and workability of coatings, adhesives, and synthetic resins. It is especially effective in improving low-temperature performance and elongation properties in PVC and other vinyl-based materials. Its hydrophilic polyether chain provides good solubility in polar solvents, making it suitable for use in specialty inks and sealants. Additionally, it acts as a reactive diluent in radiation-curable systems, helping to reduce viscosity during processing while maintaining film integrity after curing.
