Equal polyurethane lacquer is a two-component varnish of acrylic and isocyanate. How it hardens is the result of solvent evaporation and molecular polymerization resulting from the reaction of two components.
Its properties include:
This coating is used alone as the final layer of sanitary epoxy systems and drinking water to protect the surfaces against corrosion and microbes. Due to the high solid percentage of paint with a spraying step, thicknesses up to 500 microns can be achieved. Its uses include:

Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting, the surface should be completely dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface.
Steel surfaces – Wash the steel surface with a suitable solvent to remove grease, salt and any other contaminants.
De-rust and create profiles on surfaces by various methods such as sand blasting up to 2.5 degrees Swedish or by mechanical tools up to ISO-ST3 degree.
In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating a profile, remove the particles from the preparation and other contaminants from the surface with a pressure of air free of moisture and grease and with the method of vacuum and thoroughly clean.
Note that the application of the first layer (primer) should be done no later than two hours after preparation.
Concrete surfaces – If the concrete is fresh, it must be 28 days after the concrete has been applied (the concrete surface is completely dry). If the concrete is old, the surface must be washed with fresh water to remove contaminants such as salts, grease, dust and Dust, loose and unstable particles, etc. from its surface
Its properties include:
This varnish is used to prepare and seal wooden, concrete and steel surfaces and as an import for these surfaces. And this coating is very useful in the marine industry. Its uses include:
