PPG SigmaLine 523 is ideal as a solvent-free coating for the protection of pipes against the effects of potable water as it is resistant against bacterial attack. SigmaLine 523 is fast-curing, especially when applied to preheated substrates and can be applied to rotating pipes at a dry film thickness (DFT) up to 600 µm (24.0 mils) at a substrate temperature of 50°C (122°F) and up to 900 µm (36.0 mils) at a substrate temperature of 10°C (50°F), by twin-feed, hot, airless spray equipment.
Blast clean steel to ISO Sa2 1/2. An even pipe temperature ensures an even coating and appearance (flow and gloss). Do not thin. Applied in one coat. Ensure to check the WFT. Weld seams may need a thicker coat. Apply using twin feed hot airless spray. Temperature of spray unit must be between 55°C - 65°C.
