Zinga Cold Galvanizing System 96% Zinc Rich – 1 Kg / (12.66 US fl oz)

$35.09

ZINGA COLD GALVANIZING COMPOUND – 1 Kg / Can

  •  Presentation: 1 Kg / Can(2.20 Lbs) (12.66 US fl oz)
  • The Film Galvanizing System ZINGA is a one pack coating that contains 96% zinc in the dry film and provides cathodic protection of ferrous metal
  • ZINGA differentiates from galvanizing paints and other corrosion protection methods in combining both Passive and Active protection in an easily applied film galvanizing system that not only delivers active cathodic protection but also provides a passive physical shield.
  • Can be used as a unique system as an alternative to hot-dip, galvanization or metallization
  • Can be applied by brushing, rolling or spraying on a clean and rough substrate in a wide range of atmospheric circumstance
  • ZINGA has one of the fastest drying times in the coating industry. It is touch dry in around 10 minutes at 20°C (40 µm DFT). ZINGA can be recoated with a new layer of ZINGA 1 hour after touch dry (by pistol, after 2 hours by brush), and with other paints 6 to 24 hours after touch dry
  • This product is also available in presentation of 2Kg, 5Kg, 10Kg

Features

  • Can protect longer than hot-dip galvanising (at the same dft)
  • Can be applied on site
  • Can be used to re-coat existing galvanising
  • Existing layers of Zinga can be re-coated
  • Excellent primer in Duplex system
  • Good resistance to mechanical abrasion
  • Excellent adhesion
  • Extremely flexible
  • 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

Drying Time

Once dried, the Zinga film requires exposure to fresh air, carbon dioxide and moisture to become fully cured. The natural porosity of the coating is dramatically reduced as curing takes place, and Zinga continues to harden for several weeks after application.

It is very important to note that before exposure to a saline environment (i.e. submerged in salt water or placed in a salt spray zone) all zinganised surfaces will require saturation with fresh water for a minimum of two hours to properly seal them. If the coating is unlikely to be immediately exposed to a salt atmosphere then exposure to rainwater or heavy overnight condensation for a couple of days will have the same sealing effect. Zinga can also be forced dried using Infrared drying systems.

Approximate Drying Times (45µm DFT) @ 20C:

  • Touch dry in 10 minutes
  • Dry to handle in 30 minutes (using heavy lifting equipment)
  • Dry to overcoat with more Zinga in 60 minutes
  • Dried to overcoat with water-based paints in 4 hours
  • Dried to overcoat with Alufer N sealer in 4 hours
  • Dried to overcoat with 2K PU or acrylic paints in 4 hours
  • Cured to overcoat with epoxy in 24 hours

Surface Preparation

It cannot be stressed strongly enough that the key to Zinga’s long life is in the thorough preparation of the steel substrate to the correct specification.

Marine structures

  • Remove all crustacean growth using either a UHP water-jet or a high-pressure wash-down
  • Dry off
  • Blast-clean to Sa2.5 cleanliness

Old or worn galvanising, thermally sprayed zinc (TSZ) or old Zinga

  • Steam-clean to remove all contamination from porous surfaces
  • Dry off
  • Blast-clean as normal

New steel

  • Steam-clean or high-pressure wash-down all surfaces
  • Allow to dry
  • Blast-clean to a cleanliness standard of Sa 2.5

New galvanised steel

  • Steam-clean
  • Sweep-blast the surface/s at a blast-pressure of 55 psi using a 45o nozzle angle to avoid – Removing any existing zinc thickness.

Cast-iron

  • Steam-clean or high-pressure wash-down
  • Allow to dry
  • Blast-clean to SA2.5 cleanliness

Aluminium alloys

  • Solvent clean as per SSPC-SP1 Standard
  • Blast-clean with aluminium-oxide media grade 3
  • Vacuum surface/s before paint application

Note 1: The term “high pressure” means a minimum water-pressure of 10,000psi. Any pressures below this level will not totally remove engrained chlorides.

Note 2: The grit used on all structural steelwork must comply with 50µm and 80µm depending on the type of application). The chosen grit should always be able to achieve a blast roughness of 12.5 to 15 microns. It should be noted that UHP Blasting does not create a profile and should therefore never be used as the sole means of surface preparation. UHPAB is an excellent form of blast-cleaning for marine structures as it removes all crustacean growth, scale, engrained chlorides and invisible contaminants.
