Teflon or alternative coating for bolt and nut in HCl fumes

July 15, 2009

I would like to coat M16 bolt, nut and washer for acidic environment application. The previous teflon coating of 30 micron failed as it is too thin and striped off during tightening.

Hence, what is the suitable thickness for bolt & nut in this case or any other method to resist the corrosion specially by HCl fume.

thanks,

Have you looked at Epoxy powder coating... excellent chemical resistance plus outstanding adhesion to metal substrate.
