Used as a reactive diluent in epoxy resin systems to reduce viscosity without sacrificing performance. Enhances flexibility and impact resistance of cured epoxy formulations. Commonly applied in coatings, adhesives, sealants, and elastomers where improved toughness and elongation are required. Its hydrophobic nature contributes to better moisture resistance in final products. Also utilized in modifying polyurethane systems to adjust crosslinking density and improve low-temperature properties.
