Abstract:

A phosphazene material, PPZTM, is reported by Idemitsu Petrochemical Company Tokyo, Japan to have excellent chemical and abrasion resistance properties for hardcoating applications. An evaluation of the chemical resistance of this coating is presented. PPZ coated on polyethylene terephthalate PET films were challenged with simulants 2-chloroethyl ethyl sulfide CEES, 2-chloroethyl methyl sulfide CEMS, diisopropyl methyphosphonate DIMP and a decontaminant DS-2 via a droplet test method. Preliminary results showed that the PPZ coating was affected by DIMP, CEES, and CEMS as observed by optical and scanning electron microscopy, SEM. Upon visual examination, the DS-2 treated specimen did show an effect however, the coatings behavior to this corrosion liquid is inconclusive. In addition, PPZTM resin was coated on polycarbon PC using a modified ASTM D823-87 method and cured by ultraviolet light. Curing time was determined by Fourier transform infrared spectroscopy FTIR using an attenuated total reflectance ATR technique. The Taber abrasion resistance of the PPZ-coated PC specimens were slightly lower than reported values. Phosphazene, Chemical resistance, Polyethylene terephthalate, Polycarbonates, Abrasion.
