The ZINGA Film Galvanising System

1. The ZINGA Film Galvanising System

2. WHAT IS ZINGA? • Zinga was originally invented in Ghent University, Belgium, in the 1970's and has since been used on thousands of projects throughout the world. • Zinga is a unique form of corrosion protection because it provides both Active(Cathodic) and Passive protection in a form that’s as easy to apply as any primer orpaint.

3. Zingais NOT Paint! • Zinga is an active zinc performance coating which works in conjunction with the metal beneath whereas primers & paints are only passive barriers. Regardless of how thick paints are applied, they remain as barriers. • Once those barriers are breached by impact, scratching etc.. corrosion sets in immediately. Despite this significant difference, Zinga is still often mistaken for paint simply because it's liquid and comes in a tin. • But there are other more subtle differences. For example it does not “skin over” in the tin because Zinga has an unlimited pot-life and it doesn’t go “tacky” like paint.

4. Key Features & Benefits • * Protects as long as hot-dip galvanising* Can be applied on site* Can be used to re-coat existing galvanising* Existing layers of Zinga can be re-coated* Unbeatable primer in Duplex system* High resistance to mechanical abrasion* Excellent adhesion* Extremely flexible – coated steel can befolded.* Can be applied in extreme temperatures* Weldable to X-ray quality* Certified to not spread flame or create smoke (BS476 parts 6 &7)* Unlimited shelf-life and unlimited pot-life

5. What Is Galvanising • Galvanisation is the process of applying zinc to steel or iron in order to protect it from rusting. The term is derived from the name of Italian scientist and physicist Luigi Galvani. • The effectiveness of zinc against corrosion control is well documented. • The most common method is hot-dip galvanization, in which the steel is submerged in a bath of molten zinc. • Zinga contains 96% zinc in the dry film and can be described as a film galvanising system. Zinga generates the same protective voltage but is applied by spray, (conventional, airless or electrostatic) brush or roller.

6. How ZINGA Works • When two different metals come in contact with each other in presence of an electrolyte (e.g. water), they form a galvanic cell in which the lesser noble metal (e.g. Zn) corrodes in favour of the more noble metal (e.g. steel). This electrochemical reaction is the base for the complex field that is cathodic protection. • Galvanic, cathodic protection, or active protection, arises from zinc (the anode) sacrificing itself in favour of the base metal -steel (the cathode) with the resulting flow of electrons preventing steel corrosion. In this way the protection of the metal is guaranteed, even when the zinc layer is slightly damaged.

7. Continue… • Other well-established methods of cathodic protection include hot-dip galvanising (HDG) and zinc thermal spraying, both of which exhibit a constant sacrificial rate of the zinc layer. • With ZINGA the sacrificial rate reduces dramatically after the zinc layer has oxidised and the natural porosity has been filled with zinc salts. Additionally the zinc particles within the ZINGA layer are protected by the organic binder without adversely affecting the electrical conductivity. This enables ZINGA to create nearly the same galvanic potential between the zinc and the steel as hot dip galvanising but with a lower rate of zinc loss because, put simply, the binder acts as a “corrosion inhibitor” to the zinc.
