A data sheet on our Zinga cold galvanising services, a suitable summary for printing
is available in pdf format, here
Zinga is a one-component cold applied galvanic zinc coating. Its unique
formula provides environmentally safe cathodic protection to steel comparable
with hot dip galvanising, with the added advantage that it can be applied, on
site, like a paint.
 | Zinga® means
on site galvanising is possible. This therefore removes the dismantling and
transport costs associated with hot dip galvanising. |
| Due to organic binder, Zinga can
exceed lifespan of hot dip Zinc. |
| Zinga does not present any potential
hydrogen inducement to load bearing welds therefore there is no danger of
cracking. Steel coated with up to 60 um of Zinga does not require the
grinding of edges before being welded to x-ray quality. |
| Zinga can be “recharged” at any point
in the future, on site, and without re-blasting. |
| Worn or Rusty Galvanising can be also
be repaired and re-charged |
| It can be used as a primer in a duplex
system and can easily be painted over with a variety of top coats including
powder coatings |

Zinga's Organic Binder can be sensitive to solvents in top
coats. Therefore it is advisable, if a top coat is going to be
applied (The Zinc provides some anti-foul properties), that the
Zinga is sealed using a low solvent or solventless product, such
as Galvaseal or Alufer. |

Motorway Crash Barriers Trial - September
2003. White Epoxy paint cleaned & Zinga applied. Worn
Galvanising 'Brush Blasted' and Zinga applied. |
|
Zinga applied, and still wet
- although one of the major advantages of Zinga is that it
flattens off very rapidly - generally within a few minutes, the
second coat can be applied within an hour. |
