Epoxy zinc chromate polyamide primer

Zinc Chromate Epoxy Primer is a two-component epoxy-poly-hope-enhanced zinc chromate primer. How hard it is is the evaporation of the solvent and the reaction between the components.

Description of solvent-free sanitary epoxy primer

Its properties include:

Very good corrosion resistance
High chemical resistance
High abrasion resistance and hardness
Excellent water and moisture resistance
Good adhesion to steel surfaces
Applicable with thicknesses over 200 microns
Surface impermeability
Designed for health systems
Shine and excellent appearance

Uses

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:

Drinking water tanks
Water transfer pipes
Sanitary equipment
Industrial Drug Making Machines
Food Equipment
Food storage cells
Sanitary ware containers
Clean hall and operating room flooring

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, 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

Uses

This coating is used alone or as a primer for epoxy and polyurethane systems to protect surfaces in industrial, chemical and marine environments. Due to the high solid percentage of paint, a high thickness can be obtained with one spraying step. Among its uses are:

Drilling rigs and installations
Water contact facilities and equipment
Exterior parts of storage tanks
Burial pipelines
Refineries, power plants and chemical plants
Metal structures and bridges
Offshore Facilities
Industrial equipment
