  • Applications

    Oxirane, 2-propyl- (CAS 1003-14-1) is an aliphatic epoxide used primarily as a chemical intermediate in the manufacture of specialty polymers and coatings. It serves as a building block for epoxy resins and related crosslinkers; in coatings and inks it can function as a reactive diluent and a curing component; in polymer and plastics formulations it enables epoxy- or polyether-based materials; in adhesives it acts as a reactive monomer contributing to crosslinking; as a processing aid, it facilitates formulation and reaction media; and epoxy systems derived from this class of epoxides are common in electronics encapsulation and protective coatings.
