Koresin is widely used as a reactive diluent and modifier in epoxy resin systems. It helps reduce the viscosity of epoxy formulations, making them easier to process and apply in coatings, adhesives, and composite materials. Due to its ability to participate in the curing reaction, it enhances the flexibility and impact resistance of the final product without significantly compromising thermal or chemical resistance. It is particularly valued in industrial applications where improved toughness and adhesion are required, such as in heavy-duty coatings, electrical encapsulation, and construction adhesives. Its compatibility with various curing agents allows for tailored performance in demanding environments.
