ZINGA contains 96% zinc in the dry film and provides cathodic protection to ferrous metals. Zingaspray is ideal for the repair and touch up of small areas and welds on galvanized steel structures or structures coated with ZINGA.PHYSICAL DATA AND TECHNICAL INFORMATIONWET PRODUCTComponents- Zinc powder- Aromatic hydrocarbons- BinderDensity (without propellant)1,63 kg/dm³ (±0,05 Kg/dm³) at 20°CSolid content (without propellant)- 25% by volume (±2%)- 55% by weight (±2%)PropellantDimethylether (DME)Flash Point-41°C (~propellant)VOC668 g/LDRY FILMColourZinc GreyGlossMattSpecial characteristics- Atmospheric temperature resistance of dry film»Minimum: -40°C»Maximum: 120°C with peaks up to 150°C- pH resistance in immersion: 5,5 pH to 9,5 pH.- pH resistance in atmospheric conditions: 3,5 pH to 12,5 pH.- Excellent UV resistanceTemperature resistance- Minimum -40°C- Maximum +120°CPACKING500 mlAvailable.

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- Zingaspray should ideally be applied on a metal substrate that has a rough-ness grade medium G according to the standard ISO 8503-2:2012.- This can be obtained by blasting. Make sure that the surface is degreased before the blasting.- On surfaces with a hot-dip galvanisation or metallisation layer, sweep blast-ing is recommended. All zinc corrosion products must be removed in order to ensure a good electrochemical connection between the two layer. A surface profile of appr. Rz 30 μm is sufficient. For more information please consult document ‘Zinga reloading and ZINGA on HDG or METALLISATION’- For small, non-critical areas roughness can be obtained by using an electric rotative or manual steel wire brush.Maximum time to applicationApply the Zingaspray 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.ENVIRONMENTAL CONDITIONS DURING APPLICATIONAmbient temperature- Minimum 5°C- Maximum 50°CRelative humidity- Maximum 95%- Do not apply on a damp or wet surfaceSurface temperature- Minimum 3°C above the dew point- No visual presence of water of ice- Maximum 60°CProduct temperatureDuring application the temperature of the ZINGA liquid should remain between 5 and 25°C. A lower or higher temperature of the product will influence the smoothness of the film when drying.APPLICATION INSTRUCTIONSGENERALShakingZingaspray 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.ApplicationKeep the spray 30 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 or aromatic solvent.- After each use, hold the spray upside down & press on the spray button to avoid blocking upon next use.TECHNICAL DATA SHEETRef.: Technische Fiches\TDS Zingaspray.EN
