DENACOL EX-252

Polyether-type reactive diluent for versatile epoxy applications.
DENACOL™ EX-252 improves flexibility and reduces viscosity in epoxy-based systems, making it ideal for high-performance industrial uses.

Optimizing Epoxy Systems with DENACOL™ EX-252

DENACOL™ EX-252 is a difunctional epoxy resin containing an alicyclic structure, designed to deliver superior UV resistance and optical clarity in cured systems. Its unique molecular design makes it ideal for UV-curable coatings, high-performance adhesives, and applications requiring long-term color stability. Compared to traditional Bisphenol A-based resins, EX-252 offers significantly lower viscosity, enhancing formulation flexibility and processability.

Thanks to its excellent resistance to yellowing, moisture, and weathering, DENACOL™ EX-252 is particularly well-suited for outdoor applications and products with demanding aesthetic requirements.

As a globally active supplier, NAGASE offers DENACOL™ EX-252 with technical support and sourcing solutions tailored to high-performance industrial applications.
