What kind of paint is the water-based epoxy micaceous iron intermediate paint and what is it used for?

Water-based epoxy anti-corrosion paint is an environmentally friendly paint, including water-based epoxy primer, water-based epoxy zinc-rich primer, water-based epoxy micaceous iron intermediate paint, and water-based epoxy topcoat. Water-based epoxy paint is mainly used for steel structures. , bridges and other surface anti-corrosion coating, what kind of paint is the water-based epoxy intermediate paint, what is its function, and what are its uses? Let’s briefly introduce it!

Water-based epoxy micaceous iron intermediate paint

1. Water-based epoxy micaceous iron intermediate paint

Waterborne epoxy intermediate paint is prepared from waterborne epoxy resin emulsion, waterborne epoxy curing agent, mica iron oxide pigments, pigments, functional fillers, special additives, water, etc. In industrial anti-corrosion coatings, intermediate paint is one of the heavy-duty anti-corrosion coatings that most steel structure anti-corrosion projects will choose.

2. Performance of water-based epoxy micaceous iron intermediate paint

1) Using water as the diluent, it is non-toxic, odorless, non-flammable and non-explosive, with extremely low VOC emission, convenient construction and no environmental pollution.

2) The water-based epoxy zinc-rich primer has excellent anti-corrosion and anti-rust properties, and zinc powder provides cathodic protection and electrochemical anti-corrosion.

3) Fast drying and good construction performance

4) The mica iron oxide in the paint film is arranged in parallel, with excellent corrosion resistance, filling and high sealing

5) Enhance the adhesion of the bottom surface, reduce the shrinkage rate of the coating, and obviously improve the appearance of the coating.

6) Excellent oil resistance, water resistance, salt water resistance and solvent resistance.

Third, the use of water-based epoxy micaceous iron intermediate paint

The water-based epoxy micaceous iron intermediate coating is a connecting layer coating of primer and topcoat, and has excellent impermeability and shielding performance. Hard, impact resistant, most commonly used tie coat with no recoat interval restrictions.

Used between primer and topcoat, the main function is to increase the thickness of the coating and improve the permeability of the coating.

4. Commonly used supporting systems for water-based epoxy zinc-rich

Water-based epoxy zinc-rich primer + water-based epoxy micaceous iron intermediate paint + water-based polyurethane topcoat

　5. Construction technology

1) Before painting, remove the oil, rust, old paint and other dirt on the surface of the substrate to ensure that the surface of the substrate is clean and dry.

2) Grinding with the grinding wheel to remove the weld flash, spatter, and hardened layer of the pyrotechnic correction part on the surface of the workpiece. All sharp edges of free edges after gas cutting, shearing or machining shall be ground to R2.

3) Sandblasting to Sa2.5. Hot-dip galvanizing repair, hand and power tool grinding to reach St3. Construction within 6 hours after sandblasting.

4) It is recommended to use high pressure airless spraying to obtain a uniform and good coating film.

5) Maintain good ventilation during construction. Construction is not recommended when the ambient temperature is lower than 5°C or the humidity is greater than 85%.

In summary, the characteristics and uses of water- based epoxy micaceous iron intermediate paint are introduced.
