PPG SigmaGuard 730 is a two-component, moisture-curing zinc-rich (ethyl) silicate tank coating. For use as tank coating or as a system primer in various paint systems based on unsaponifiable binders, with a high zinc content that results in excellent corrosion protection.
PPG SigmaGuard 730, a two-component, moisture-curing zinc-rich (ethyl) silicate tank coating with excellent solvent and chemical resistance that can withstand substrate temperatures from –90°C (–130°F) up to 400°C (750°F), under normal atmospheric exposure conditions.
SigmaGuard 730 is used as tank coating or as a system primer in various paint systems based on unsaponifiable binders, with a high zinc content that results in excellent corrosion protection.
