Alkaline zinc chromate zinc primer as an anti-corrosion primer is widely used for metal structures, which is due to the presence of anti-corrosion pigment zinc chromate zinc in this paint, which has made the surfaces resistant to atmospheric and moisture factors. This primer is usually applied by brush on the work surface, which causes better penetration into the pores of the surface and creates good adhesion and resistance against corrosive agents. Also in cases where the metal surface is not completely clean. Using a brush creates better adhesion. This primer is usually applied as a first or middle layer on a suitable primer.
Its properties include:
This color is widely used for marking and marking roads and passages, including its uses are:

Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting the surface must be perfect
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 thoroughly to remove grease, salt and any other contaminants. De-ring and create
Profiles on surfaces by various methods such as ballast document up to 2.5 degrees Swedish SA or by mechanical tools up to ST3-ISO degree
(SP10-SSPC).
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 the profile of the particles obtained from the preparation and other contaminants, remove the surface with moisture and grease free from moisture and grease by vacuum method. Note that the application of the first layer (primer) should be done no later than two hours after preparation.
After preparing the surface and choosing the method of painting, first mix the fabric of the relevant solution with the recommended ratio and mix the mixture thoroughly to make it uniform.
Add a special amount of ethyl silicate thinner if needed (usually not needed) (add to the mixture and stir until a primer is applied, then apply the paint with a suitable tool.

Epoxy varnish is characterized by high transparency and high resistance to abrasive agents, as well as its application with high thickness for all metal and wood cement surfaces. Epoxy resin is two-component and without solvent and its composition ratio to hardener is two to one. This resin can be used for molding decorative works and ornaments. This varnish is also used to apply the final three-dimensional epoxy coating of the floor.
Its properties include:
This primer is used to protect steel structures against corrosive agents in marine or urban industrial environments and has good adhesion even on surfaces cleaned with hand tools. It should be noted that this liner is not suitable for protecting structures immersed in water. Among its uses are:
