SIGMA Z-COAT Ideal Coating For Corrosion Protection

In the SIGMA Z-COAT process, the zinc coating is applied by spraying zinc-rich paint onto the surface. It complies with ISO 8179-2 specs.

The zinc-rich paint, or SIGMA Z-COAT method, is considered superior for use on fittings and other products with rough surfaces and non-uniform shapes. Because it is applied as a liquid, SIGMA Z-COAT permeates all surfaces and fills the peaks and valleys formed in the fitting manufacturing process. This prevents voids in coverage, which can result in corrosion and ultimately, failure.
