Zingatarfree (formerly PU Tarfree MIO), a one-pack polyurethane paint with excellent water and corrosion resistance, ideal for use in offshore and in-land marine environments and as a replacement for normal coal tar products.

Recommended for use in duplex systems with Zinga for application on structures in immersion or embedded in soil, Zingatarfree can be painted directly over Zinga on narrow-boat hulls, tug-boats, on the base of electricity pylons-legs (to keep out both local ground-water and also stray-currents from nearby electrified railway tracks) and also on brand-new truck chassis.

Features

• Apply by brush, roller, conventional spray-gun or airless spray
• Excellent chemical and salt resistance
• Ideal for immersion & subterranean applications
• Poison free - does not leach poisonous phenols into the environment

Application

Zingatarfree can be applied on top of ZINGA by brush and roller, conventional spray-gun or airless spraying.

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

• Nozzle opening: 0.017 to 0.024 inch

One Zinga

Mist (tie) coat

• 20-30 μm DFT (Dry Film Thickness; to be measured above the peaks of the roughness profile), diluted 10-15%

Full coat

• 2 hours after touch dry, DFT no more than 70-80 μm per layer

Coverage

DFT = Dry Film Thickness; to be measured above the peaks of the roughness profile

Theoretical coverage

• For 80 μm DFT: 8,3 m²/L
• For 100 μm DFT: 6,6 m²/L
• For 150 μm DFT: 4,4 m²/L

Theoretical consumption

• For 80 μm DFT: 0,12 L/m²
• For 100 μm DFT: 0,15 L/m²
• For 150 μm DFT: 0,23 L/m²

Drying Times

For 80 μm DFT at relative humidity of 75%:

Drying time before immersion - A curing time of 3 days has to be respected before immersion of the Zingatarfree.

Overcoating

For 80 μm DFT at relative humidity of 75%:

Note: At longer intervals a good cleaning is necessary to avoid intermediate coat contamination which could disturb the adherence of the next coat.

Recommended System

Tested according to ISO12944 in immersion in salt or brackish water (Im²) or in the ground (Im3) with high classification (Life expectancy > 15 years):

ZINGA 1 x 60-80 μm DFT

Zingatarfree 2 x 100 μm DFT
