Webtannic acid treatment on the surface. Tannic acid forms a complex with iron oxides present on the surface, creating a passivating layer that can help to prevent future rust. The major caveat with tannic acid is that it produces a dark purple-ish surface appearance; if this will detract from your object, it is likely not a suitable choice. WebJASH C. I. Surface Plates are now offered with ISI marking conforming to latest IS: 2285/1991.
