Dipping

Zinga can be used in dip tanks for fast application onto blast-cleaned or phosphated steelwork. Where the steelwork is to be phosphated, it must have a minimum weight of 1200 – 1500 g/m2. The viscosity of the liquid zinc in the tank will determine the final dried film build of the zinc layer.

Items can only be dipped once, and never double-dipped, as this causes slight waves on the zinc surface. The zinc can be force dried in either low bake ovens at 40°C or in a standard powder coat oven at 180 – 200°C. Short-wave infrared ovens dry the zinc film in 2 minutes.

After dipping in the zinc tank, articles can be sent straight through the oven without waiting for a flash-off period. Once the dried Zinga coated items leave the oven and cool down to below 50°C they can be coated with powder or wet paints.
