It is a conversion coating that produces a uniform, attractive, and non-reflective black finish on stainless steels. It provides a permanent black colour with exceptional strength and elasticity. The finish does not chip, peel, craze, or rub off and provides good resistance to wear and abrasion. The coating reduces friction of moving parts, preventing galling and scoring. Improved corrosion resistance is obtained and there is a negligible dimensional build up, smooth screw assembly is assured.
