ŽEMIAU APRAŠYMAS ANGLŲ KALBA
.Alu ZM is a quick drying one pack coating based on aluminium flakes. It can be applied either without primer on an old, non-corroded hot-dip galvanisation or metallisation layer or as topcoat on top of Zinga. It can be applied by brushing, rolling or spraying in a wide range of atmospheric circumstances. Alu ZM is mainly applied for esthetical reasons as it gives a nice aluminium aspect and has a good chemical resistance which allows it to be used in industrial environments.

System recommendations
As topcoat on Zinga
Alu ZM can be applied in 1 layer of 40 to 60 μm DFT as topcoat (by roller, airspray or airless) on top of the anti-corrosion system Zinga on a metal substrate. Even though we always recommend maximum 60 μm DFT for Zinga in a duplex system, in combination with Alu ZM, the maximum layer thickness of Zinga is 120μm DFT in 1 layer applied by airless.
Stripe-coat
We recommend applying a stripe-coat of Alu ZM by brush on all sharp edges, nuts and bolts and welding areas before the application of the first full layer of Alu ZM.

•
Drying process and overcoating
Drying process
Alu ZM dries by evaporation of the solvent. The drying process is influenced by the total WFT, the number of coats applied, the ambient air and surface temperatures and the air circulation.
Drying time
for 40 μm DFT at 20°C in a well-ventilated environment with at least 60% relative humidity :
-
touch-dry : after 25 min.
-
dry to handle : after 1,5 hour
-
fully cured : after 24 hours
Overcoating
-
with a new layer of Alu ZM : 1 hour after touch dry
-
Any intermediate coat contamination that could disturb the adherence of the next coat should be removed by appropriate cleaning.
Reliquidisation
Each new layer of Alu ZM reliquidises the former Alu ZM layer so that both layers form one homogeneous layer.

Instructions for use
•
Surface preparation
Cleanliness
-
When Alu ZM is applied on top of Zinga, the surface should be free of zinc salts and other contaminations. That means that the Alu ZM must be applied within 24 hours after the application of the Zinga. In case the application of the Alu ZM can only be done after 24 hours, the Zinga surface should first be washed preferably by steam-cleaning at 140 bar at 80°C.
Roughness
When Alu ZM is applied on top of a new hot-dip galvanisation layer, the surface should be roughened by blasting with wet inert product, by using Scotch Brite or a nylon brush.
Maximum time to application
Apply the Alu ZM as soon as possible on the prepared surface.
-
in dry circumstances : max. 24 hours waiting time
-
if the relative humidity is close to 80% : max. 4 hours waiting time
If contamination occurs before coating, the surface must be cleaned again as described above.
•
Special instructions
Stirring
-
Alu ZM must be thoroughly stirred to achieve a homogeneous liquid before application. After a maximum of 20 min. re-mixing is necessary.
-
During the spraying application, the product must be stirred continuously.
Dilution
Alu ZM can only be diluted with Zingasolv.
Rinsing of tools and equipment
Before and after using the spraying equipment, it must be rinsed with Zingasolv. Brushes and rollers should also be cleaned with Zingasolv. Never use White Spirit.
•
Application by brush and roller
Viscosity
Alu ZM is ready for use when applied by brush or roller. Do not dilute.
First layer
When the Alu ZM is applied directly without primer on an old hot-dip galvanisation or metallisation layer, then the first layer must never be applied by roller, only by brush, in order to fill the cavities of the roughness profile and to wet the surface.
Type of brush and roller
-
short hair roller (mohair)
-
industrial round brush
