PPG NovaGuard 840 is a two-component, solvent-free, amine-cured novolac phenolic epoxy coating suitable for heavy H2S wastewater environments. such enviroments include unleaded fuel tanks, particularly in aviation, with good chemical & solvent resistance, especially to crude oil up to 120°C (250°F).
PPG NovaGuard 840, is a two-component, solvent-free, amine-cured novolac phenolic epoxy coating for heavy H2S wastewater environments suitable for unleaded fuel storage in sectors, such as aviation. Novaguard 840 has good chemical and solvent resistance, and is particularly resistant to crude oil (up to 120°C (250°F). The coating applies to primed steel or directly to concrete and masonry with a glossy and smooth appearance, and can be applied by heavy-duty, single-feed, airless spray equipment (60:1).
NovaGuard 840 meets the requirements of EI 1541 2.2 (coating systems for aviation fuel storage tanks and pipes) & NSF/ANSI Standard 61 for potable water when applied and used as described.
