Used as a reactive diluent in epoxy resin systems to reduce viscosity without sacrificing performance. Enhances flexibility and impact resistance of coatings, adhesives, and composites. Commonly added to improve resin flow in electrical encapsulation and casting applications. Also utilized in modifying polymers for better adhesion to substrates like glass, metal, and concrete. Its multifunctional epoxy groups enable crosslinking, contributing to durable, chemically resistant end products.
