To judge which rust protection paint is the best, you need to consider its anti-corrosion effect, durability, environmental performance and ease of construction. The following are several common types of high-quality rust protection paint: 1. Epoxy zinc-rich primer 2. Alkyd anti-rust primer 3. Acrylic anti-rust primer

If the solvent does not evaporate sufficiently or the cross-linking reaction is not completely carried out, the coating may have too many soft components remaining, resulting in a sticky surface. This situation is common in the following construction environments: ·High humidity environment ·Low temperature conditions

Micaceous iron oxide paint is generally divided into two types: ● Primer type: mainly used for the bottom coating of steel or other metal surfaces to enhance the anti-rust effect and provide adhesion for subsequent coatings. ● Topcoat type: used for surface decoration and further enhance the protective function, giving the paint surface gloss and texture.

Anticorrosive paint is the base coating in the ship painting system. Its main function is to prevent seawater from corroding the hull metal. Commonly used anticorrosive paints include epoxy and zinc-rich anticorrosive paint.

Polyurethane is a high molecular polymer with strong chemical bonds in its structure that make it highly hydrophobic. After being applied to the surface, the polyurethane coating can form a dense, non-porous film that effectively blocks the penetration of water.

The main function of fire retardant paint is to delay the impact of fire on steel and ensure that the steel structure maintains its bearing capacity and structural stability for a long enough time in a high temperature environment. Fire retardant paint can form a heat-insulating protective layer through physical and chemical reactions, reducing the heat conduction and temperature rise rate on the surface of the steel.

If the old paint is in good condition and the new and old paints are compatible, the new paint can be applied directly by cleaning and sanding. However, if the old paint is severely damaged, incompatible or the paint layer is too thick, it is recommended to completely remove it to ensure the performance of the new coat.

Copper ions can interfere with the cell metabolism and respiration process of aquatic organisms, inhibit the growth of algae, shellfish, plankton and marine microorganisms, thereby preventing these organisms from attaching to the bottom of the hull.

The impact of harmful substances in marine antifouling paint on the marine ecosystem is one of the main reasons for prohibiting its use. The marine ecosystem is complex and sensitive, and harmful substances in marine antifouling paint may destroy the balance of this system.

The waterproof effect of polyurethane waterproof paint is closely related to the number of layers applied. In building construction, it is usually recommended to apply 2 to 3 layers of polyurethane waterproof paint to ensure that the coating thickness is uniform and dense to achieve the best waterproof effect.
