The Role of Epoxy Cloud Iron Intermediate Paint

The role of Epoxy Cloud Iron Intermediate Paint
1. The role of Epoxy cloud iron intermediate paint
1. Strengthen the anti-rust and anti-corrosion effect: good shielding performance, increase the physical anti-rust effect of the coating. Water vapor, electrolyte, etc. should not penetrate into the substrate and react with the substrate. Benefit from the scaly mica iron oxide coating.
2. Reduce coating costs: The thickness of the paint coating has a significant impact on the effect of anti-corrosion and anti-rust. Specification for the total design thickness of anticorrosive paint coatings for steel structures: 120μm indoors and 150μm outdoors. The intermediate paint coating has the same anti-corrosion effect, and the cost is lower than that of only the primer top coat.
3. Extend the anti-corrosion period: the same thickness of the coating, in the case of conforming to the design specifications, use the anti-corrosion coating of the intermediate paint, and the service life is longer than that of the coating that only uses the primer and top coat.
4. Special purpose: epoxy mica Epoxy cloud iron intermediate paint is used as a sealer on the surface of inorganic zinc-rich primer; when the topcoat is an alkyd modified topcoat, the zinc-rich primer should be used with epoxy mica intermediate paint.
2. The difference between Epoxy cloud iron intermediate paint and epoxy mica antirust paint
1. The epoxy mica anti-rust paint prepared by adding mica in epoxy resin is one of the important paint varieties after alcohol phenolic mica. It is widely used as an anti-rust base in heavy-duty coating systems. Paint and intermediate paint use.
2. Epoxy mica anti-rust paint, as the name implies, has long been used as an anti-rust primer. Due to its good anti-permeation effect in the coating film, Mica is widely used as intermediate paint in heavy-duty anticorrosive coating systems. It is often used in conjunction with epoxy inorganic zinc-rich primer and aliphatic polyurethane top paint.
3. The Epoxy cloud iron intermediate paint developed on this basis adds more stuffing box mica to further strengthen the shielding effect. It can only be used as an intermediate paint, not as an anti-rust primer.
4. Prototype epoxy mica intermediate paint, the volume solid content is less than 80%, and the mica composition (volume ratio) accounts for more than 80% of the pigment. Thick film construction can be used, and the dry film thickness of single construction can reach 100～300μm. Epoxy cloud iron intermediate paint, it is better to use zinc-rich primer as the anti-rust primer to increase the anti-rust performance of the entire coating system.
