Epoxyden PA & DU/Zn is two a component Epoxy primer paint suitable especially as primer for galvanized steel (hot and cold galvanization). It is based on special resins and pigments providing excellent adhesion to the galvanized metals. Creates a strong basis, which is the first condition, for stable top painting on galvanized steel,

Properties

Excellent adhesion to galvanized steel.
A strong and durable primer for top paints.
It has excellent mechanical strength.
Resistant to scratches.
Resistant to diluted alkali or acids as well as to extreme humidity.
Durable for dry heat up to 200^OC for short exposure time.
Suitable as primer paint for various top paints such as polyurethane, epoxy, chlorinated rubber, syntactic etc.
Easy to apply, dries quickly.
High coverage as a very thin layer needed.
Durable in fuels, oils, jet fuels etc.

Primer:

This product itself.

Top color:

You can paint the top layer 8-12 hours after painting the primer if it had the heat and dryness condition.
During the cold winter, you can paint only after 24 hours.
The top layer can be “Denbergloss” aliphatic exterior polyurethane paint with UV resistance.

Instructions for use:

Open carefully parts A and B and stir separately.
Pour from two parts in the right ratio the required amount and mix well with mechanical mixer (operated by air pressure is recommended for safety reasons) for a uniform mixture.
Wait for 15 minutes while adding the thinner as needed and mix again. Spray a thin layer of at least 20 microns thickness dry film. If necessary if the layer does not completely uniform or part of surface not painted, wait about 4-12 hours for complete drying and spray another layer. Insert into clean and controlled temp. drying room for 12 hours before painting the top layer.
Wash the equipment well immediately after finishing painting.
