Uses

This primer is used as a primer for sanitary epoxy systems and drinking water to protect surfaces against corrosion and germs. Due to the high solid percentage of paint with a spraying step, a high thickness can be achieved. Its uses include:

• Drinking water tanks
• Water transfer pipes
• Sanitary equipment
• Industrial Drug Making Machines
• Food Equipment
• Food storage cells
• Sanitary ware containers

Surface preparation

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, 28 days must have passed since the concrete was 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. should be removed from its surface. It is recommended to use alkaline degreasers to remove all contaminants, if necessary, especially in the case of old concretes. The washing operation with water should be repeated after degreasing. In order to create a suitable roughness, both chemical and mechanical methods can be used. In the mechanical method, a suitable roughness is created on the surface by a mechanical power tool and finally by normal air pressure. From moisture and grease or by vacuum method, the surface is cleaned of all the remaining particles and is ready to be painted. In the chemical method, the surface roughness is done by suitable acids on concrete (acid pickling). Finally, the surface is washed with fresh water and after drying, it is ready to be painted.

Staining instructions

After preparing the surface and choosing the method of application, first stir the paint to mix thoroughly, make sure that no sediment remains at the bottom of the container. Add a special amount of epoxy thinner (the amount depends on the method of application) to the mixture. Stir until the color is applicable. Then apply the paint with the appropriate tools.

Storage and transportation

The above paint is flammable, so it should be sealed in a sealed container and kept away from moisture, fire, and strong currents of electricity and incendiary materials. It is recommended to consume the contents of the container as soon as possible after opening the lid. Suitable storage temperature is 20 degrees Celsius.

Safety

When applying paint, use safety equipment such as masks, goggles, cape and proper ventilation. In case of contact with skin, clean the area with a cloth soaked in a suitable solvent and wash with plenty of warm water and soap. Avoid breathing paint vapors, especially during application.
