EPOSIR®/EPONAC®
Epoxy resins
We offer a wide range of versatile thermosetting epoxy resins. Under the brand name of EPOSIR® and EPONAC® we manufacture different types of epoxy resins for many applications such as anticorrosion coatings, solvent-borne coatings, water-borne coatings, can & coil coatings, powder coatings, civil engineering, adhesives, composite materials and many others. In this section are also included few cycloaliphatic products under the brand name of SIRION® CE.
SIR INDUSTRIALE is known to be one of the few producers using two different types of manufacturing processes for epoxy resins: EPOSIR® resins are produced with the so called “advancement process” and EPONAC® resins are produced by “Taffy process”.
