Storage

Store vertically in a dry environment at temperatures between 5°C and +35°C (preferably at room temperature ±18°C).

Surface preparation

- ZINGALUSPRAY can be applied on ferro-metals and damaged zinc surfaces.

- For optimal performance, the metal should first be degreased, preferably by steam-cleaning. Alternatively, the surface can be degreased using solvent (e.g. ZINGASOLV), but never use white spirit.

- For optimal performance, clean to SA 2,5 (ISO 8501:2007). For non-critical (small) areas, cleaning to St 3 is sufficient (using a steel brush).

Roughness

- ZINGALUSPRAY should be applied on a metal substrate that has a roughness grade of fine to medium G (Rz 50 to 100 μm) according to the standard ISO 8503-2:2012.

- Such a level of roughness is not needed when ZINGAUSPRAY is applied on a hot-dip galvanisation or a metallisation layer, or when it is applied on top of an

existing ZINGA. Old hot-dipped surfaces have adequate roughness, new hotdipped surfaces require a sweep blast

- For small, non-critical areas, roughness can be obtained by using a steel wire brush or sand paper.

Maximum time to application

Apply the ZINGALUSPRAY as soon as possible on the prepared metal substrate before any contamination or corrosion occurs before coating. Otherwise the surface must be cleaned again as described above.

Ambient temperature

- Minimum 0°C

- Maximum 35°C

Relative humidity

- Maximum 90%

- Do not apply on a damp or wet surface

Surface temperature

- Minimum 3°C above the dew point.

- No visual presence of water of ice

- Maximum 60°C

Shaking

ZINGALUSPRAY must be shaken thoroughly before application. Shake the can vigorously for minimum 30 seconds after liberating the balls. Repeat this every time the can is not used for some time.

Application

Keep the spray between 10 and 20 cm away from the substrate and move in a continuous speed from left to right. Repeat with a spray application from top to bottom.

Cleaning

Cleaning of equipment or spills with ZINGASOLV

Theoretical coverage

For 40 μm DFT: 4,30 m²/L

Theoretical consumption

For 40 μm DFT: 0,23 L/m²

Practical coverage and consumption

Depends upon the roughness profile of the substrate and the application method

Drying process

Zingalu dries by evaporation of the solvent. The drying process is influenced by the total WFT, the ambient air (humidity and temperature) and the steel surface temperatures.

Drying time

For 40 μm DFT at 20°C in a well-ventilated environment:

Dust dry: 15 minutes

Touch dry: 30 minutes

Dry to handle: 1 hour

Fully cured: 24 hours

Overcoating with a new layer of ZINGALUSPRAY

- Always apply 2 layers, apply the second coat 1 hour after touch dry.

- Maximum overcoat time depends on environmental conditions. If zinc salts have formed, they should first be removed.

Unique system

ZINGALUSPRAY is advised for touch-up (HDG, metallisation or on ZINGA) and application on small areas only.

It should be applied in two layers.
