PPG SigmaGuard 750 is a two component, moisture curing, zinc rich silicate coating used as a tank coating to provide excellent solvent and chemical resistance in harsh conditions.
SigmaGuard 750 can be used as a tank coating or as a system primer, part of various paint systems based on unsaponifiable binders.
PPG SigmaGuard 750 is best used to provide corrosion protection to tanks that are exposed to adverse weather conditions on a daily basis. SigmaGuard 750 can withstand extreme temperatures of up to -90°C right up to 400°C, providing the atmospheric conditions are normal. Resistant to jet fuel and kerosene.
PPG SigmaGuard 750 can be applied easily using air or airless spray once the two components have been mixed together following careful instructions. SigmaGuard 750 is extremely fast drying and provides users with a touch dry finish after just 30 minutes at 20°C. SigmaGuard 750 has a theoretical coverage rate of 8.7m2 per litre, suitable for the coating of tanks.
