PPG SigmaFast 20 is a single pack zinc phosphate primer for use as a one-coat, anti-corrosive finish for structural steel.
PPG SigmaFast 20 (formerly Amercoat 4116) is a red oxide single pack, high build, zinc phosphate primer based on a modified alkyd resin. It is a fast drying primer with anti-corrosive properties and is part of the PPG Sigma range, offering toughness and durability with a worldwide reputation.
PPG SigmaFast 20 provides protective finish for structural steelwork, in a single coat. SigmaFast 20 has good anti-corrosive properties and is suitable for use in conditions which are subject to atmospheric exposure.
PPG SigmaFast 20 should be applied air or airless spray, to achieve the best results, but can be applied with a brush or roller to touch up small or damaged areas. Ensure that there is adequate ventilation and stir SigmaFast well, before use. Surfaces must be clean, dry and free from contaminants. After thirty minutes the coating will be touch dry, and it will be re-coatable after approximately 4 hours at 20°C.
