Zinga - ZINGALUFER Grey 5 L

Zinga - ZINGALUFER Grey

Zingalufer, previously known as Alufer N, an intermediate layer or topcoat for existing layers of Zinga in immersed or chemical environments, such as ship hulls and sewage works, providing a protective seal against salt and chemical exposure.

• Apply by brush, roller, conventional sprayers or aireless spray
• One pack system
• Dry in as little as 4 hours
• Protects against salt and chemical exposure
• Ideal for use in immersed or chemical environments

A moisture curing one pack polyurethane, micaceous iron oxides (MIO) create a special lamellar structure which create a very tight paint film for optimal barrier protection and corrosion resistance. Zingalufer is used as a sealer on Zinga, an intermediate coat in a three layer Zinga system. In covered areas where there is no UV exposure, Zingalufer can be used as a topcoat.

Application:

Brush and Roller

• Dilution: 5 to 10% with Zingasolv (v%)

Conventional Spray-Gun

• Dilution: 10 to 15% with Zingasolv (or Thinner 41)
• Pressure at the nozzle: 3 to 5 bar
• Nozzle opening: 1.2 to 1.5 mm

Airless Spray

• Dilution: 5 to 15% with Zingasolv (or Thinner 41)
• Pressure at the nozzle: 100 to 300 bar
• Nozzle opening: 0.017 to 0.024 inch

On Zinga

Mist (tie) coat

• Application at least 6 hours after Zinga is touch dry.
• 25-30 μm DFT (Dry Film Thickness; to be measured above the peaks of the roughness profile)
• Diluted according to the data sheet

Full coat

• 2 hours after touch dry of mist coat
• DFT = specified DFT - 20-30 µm DFT
• Diluted according to the data sheet
