PPG Industries' protective and marine coatings business has introduced Novaguard, Phenguard and Sigmaguard CSF coatings for petrochemical and biofuel storage tank lining applications in the U.S. The addition of solvent-free Novaguard and Sigmaguard CSF coatings and of solventborne Phenguard coatings provides storage tank owners and maintenance engineers with a comprehensive range of PPG tank lining solutions for all types of chemical storage.
Sigmaguard CSF 650 coating is a solvent-free, single-coat, amine-cured epoxy lining for tanks that contain aliphatic petroleum products or crude oil at temperatures of up to 140 degrees Farenheit. It can be used to line new tanks and repair pitting corrosion damage or as a reinforced lining for refurbished tank bottoms.
Solvent-free Novaguard 840 coating is a single-coat, novolac phenolic epoxy for tanks storing solvents, chemicals, refined fuels and crude oil at temperatures of up to 194 degrees Farenheit. As a maintenance or repair coating, it is well suited for filling difficult "omega" pit holes.
Novaguard 890 coating is a solvent-free, single-coat, novolac phenolic epoxy lining that meets emerging petrochemical industry requirements for the storage of biofuels, including ethanol fuel blends. In addition to holding crude oil at temperatures of up to 194 degrees Farenheit, Novaguard 890 coating can be used to store aggressive biofuels, such as gasolines with five to 95 percent ethanol. Like Novaguard 840 coating, it has excellent pit-filling characteristics and can be used as a reinforced lining for refurbished tank bottoms.
Solvent-based Phenguard 930/935/940 coatings provide a lining system for tanks storing the broadest range of chemicals and refined products, including highly aggressive materials such as methanol, ethylene dichloride (EDC), caustic sodas and fatty acids.
