                      Material Notes:
                      Monomer is para-xylylene. Parylene N has a lower coefficient of friction and therefore is recommended where lubricity is needed. Parylene N exhibits a slight haze at thicknesses over 5 microns.Parylene is a generic name for poly-para-xylylene polymers used as conformal coatings in protective applications.The coating process exposes objects to the gas-phase monomer at low pressure. Through vacuum deposition, Parylene condenses on the surface in a polycrystalline fashion, providing a coating that is truly conformal and pinhole free.Compared to liquid processes, the effects of gravity and surface tension are negligible -- so there is no bridging, thin-out, pinholes, puddling, run-off or sagging. And, since the process takes place at room temperature, there is no thermal or mechanical stress on the object.Parylene is physically stable and chemically inert within its usable temperature range. Parylene provides excellent protection from moisture, salt spray, corrosive vapors, solvents, airborne contaminants and other hostile environments.Property data obtained following ASTM methods.
