Used as a key building block in the production of high-performance polyurethanes and polyester resins, offering improved flexibility, durability, and chemical resistance. Commonly found in coatings, adhesives, sealants, and elastomers due to its ability to enhance water resistance and low-temperature performance. Also utilized in personal care products as a solvent and humectant, providing moisturizing effects in skin and hair formulations. Its low volatility and high stability make it suitable for industrial applications requiring long-term performance under harsh conditions.
