Polysiloxane cvd coating metal
WebThe use of polysiloxane as a description for a coating was as much marketing as a chemical description, since to a chemist, all silicones are polysiloxanes. The first polysiloxane-labeled coating came out in the mid 1990s and just as with inorganic zinc, its original purpose was not as an elevated-temperature coating. At this time, the standard ...
