p. 1/6ZM-RE-PRO-04-B (02/09/14)www.zinga.euZINGAThe Film Galvanising System ZINGA is a one component coating that contains 96% zinc in the dry film and provides cathodic protection of ferrous metals. It can be used as a unique system as an alternative to hot-dip galvanisation or metallisation, as primer in a duplex system (active + passive) or as a recharging system for hot-dip galvanisation, metallisation or zinganised surfaces. It can be applied by brushing, rolling or spraying on a clean and rough substrate in a wide range of atmospheric circumstances.ZINGA is also available as an aerosol and is sold as Zingaspray.PhysIcAl dAtA ANd techNIcAl INformAtIoNWet ProductComponents- Zinc powder- Aromatic hydrocarbons- BinderDensity2,67 kg/dm³ (±0,06 kg/dm³)Solid content- 80% by weight (±2%)- 58% by volume (±2%) according to ASTM D2697 Type of thinnerZingasolvFlash point≥ 40°C - 60°CVOC474 g/L (EPA Method 24) (=178 g/kg) measured by SMI, Inc. dry fIlmColourGrey (colour changes depending on environment)GlossMattZinc content96% (±1%) by weight, with a purity of 99,995%.ZINGA gives full cathodic protection and conforms to the standard ISO 3549 in regard to its zinc purity and to the standard ASTM A780 in regard of its use as repair coating for hot-dip galvanisation.Special 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 resistanceNon-toxicityA dry layer of ZINGA is not toxic.

In case of long time storage it is recommended to shake the unopened tin in an automatic shaker at least once every 3 years.StorageStore in a cool and dry place at temperatures between 5°C and +25°C.Pot lifeIf closed correctly after usage, ZINGA will remain applicable.coNdItIoNssurfAce PrePArAtIoNCleanliness- The metal substrate should first be degreased, preferably by steam-clean-ing at 140 bar at 80°C. After that it should be blasted to a cleanliness degree sA 2,5 according to the standard ISO 8501-1:2007 or to the cleanliness degree as described in the standards SSPC-SP10 and NACE nr 2. This means that the surface must be free from rust, grease, oil, paint, salt, dirt, mill scale and other contaminants. Once the blasting is completed the surface should be de-dusted with non contaminated compressed air according to the standard ISO 8502-3 (max quantity 2) or in the case of wet blasting the surface should be dried with non contaminated compressed air.- Another method to obtain a clean surface is uhP water-jetting to clean-liness degree SSPC-SP-WJ1. But keep in mind that this method does not create surface roughness.- Such a level of cleanliness is also needed when ZINGA is applied on a hot-dip galvanisation or a metallisation layer, or when it is applied on top of an existing ZINGA layer, but not the same roughness degree (see further). - On small areas or on non-critical applications ZINGA can be applied on a surface that is manually prepared to degree St 2 according to ISO 8501-1.Roughness- It is recommended to apply ZINGA on a metal substrate that has a rough-ness grade of medium G according to the standard ISO 8503-1:2012. - make sure that the surface is degreased before the blasting.- Such a level of roughness is not needed when ZINGA 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 hot-dipped surfaces require a sweep blast or adequate power tool roughening.Maximum time to applicationApply the ZINGA 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.Please consult a Zingametall representative / distributor.techNIcAl dAtA sheetRef.: Technische Fiches\TDS ZINGA.EN
