Zingaceram PU is a two-pack system recommended as a finish topcoat in a Zinga system, available in most RAL colours for an exceptional barrier against the environment which results in high chemical and abrasion resistance due to its ceramic particles (inorganic, non-metallic materials).

The ceramic fillers in this acrylated polyurethane paint are extremely hard wearing to prevent erosion of the surface from wind-blown sand and dust particles. In conjunction with Zinga and Zingaceram HS primer-sealer it was used to coat steelwork of the Olympic structures in London, the system given an expected service-life of 60 years to first major maintenance.

Available in a 4 litre size consisting of Part A (base) of 3.5 L and Part B (hardener) 0.5 L with a medium-gloss finish.

This product is made to order and has an extended lead time of 10+ working days.

Mixing

Mix base paint and hardener (mixing ratio: 7/1 in volume). Mixing errors result in deviating properties and differences in gloss, therefore it is advised to mix the complete contents of base paint and hardener.

By Brush and Roller

• Dilution 0 to 5% with PU Thinner (v%)

Application By Conventional Spray-Gun

• Dilution: 10 to 20% with PU Thinner (v%)
• Pressure at the nozzle: 3 to 5 bar
• Nozzle opening: 1,2 to 1,8 mm

Application By Airless Spray

• Dilution: 0 to 10% with PU Thinner (v%)
• Pressure at the nozzle: 100 to 300 bar
• Nozzle opening: 0,017 to 0,024 inch

Application On Zinga

Mist (tie) coat:  20-30 μm DFT (Dry Film Thickness; to be measured above the peaks of the roughness profile), diluted 10-15%, continuous layer.

Full coat 2:  hours after touch dry, DFT no more than 120 μm per layer.

Coverage

Theoretical Coverage

• For 60 μm DFT: 10 m²/L
• For 80 μm DFT: 7,5 m²/L

Theoretical Consumption

• For 60 μm DFT: 0,103-0.118 L/m² depending on colour choice
• For 80 μm DFT: 0,138-0.157 L/m² depending on colour choice

Drying Process and Overcoating

Drying time For 60 μm DFT at relative humidity of 75%:

Overcoating For 60 μm DFT at relative humidity of 75%:

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

Recommended System

Zinga Duplex System

Zingaceram PU can be applied directly onto Zinga (apply with mist/full coat technique).

• Zinga 1 x 60-80 µm DFT + Zingaceram PU 1 x 60-120 µm DFT

Zinga Triplex System

For optimal gloss and extra barrier protection, a triplex system (with sealer) is recommended.

• Zinga 1 x 60-80 µm DFT + Zingaceram HS 1 x 80 µm DFT + Zingaceram PU 1 x 60-80 µm DFT (recommended)

Tested according ISO 12944 obtaining a High classification in a C5I environment (life expectancy > 15 years).

• Zinga 1 x 60-80 µm DFT + Zingalufer 1 x 80 µm DFT + Zingaceram PU 1 x 60-80 µm DFT

Will show equal performance as the system Zinga + Zingalufer has been tested according ISO 12944 obtaining High classification in a C5I environment.
