The long-lasting protection of high-activity reactive catalyst ZF-10 in marine anti-corrosion coatings
Introduction
Ships sail in marine environments for a long time and face severe corrosion challenges. Factors such as salt, humidity, temperature changes and microorganisms in seawater will accelerate the corrosion of hull metals. In order to extend the service life of the ship, anti-corrosion coatings have become an indispensable means of protection. In recent years, the application of the highly active reactive catalyst ZF-10 in marine anti-corrosion coatings has gradually attracted attention. This article will introduce in detail the characteristics, mechanism of action, product parameters and its long-lasting protection effect in ship anti-corrosion coatings.
1. Characteristics of ZF-10 catalyst
1.1 High activity
ZF-10 catalyst has extremely high activity and can quickly start the reaction at low temperatures, effectively reducing the curing time and energy consumption of the coating. Its high activity allows the paint to form a dense protective film in a short time, enhancing the corrosion resistance.
1.2 Reactive Type
ZF-10 is a reactive catalyst that can react chemically with resin and curing agent in coatings to form stable chemical bonds. This reactive characteristic allows the coating to have better adhesion and durability.
1.3 Environmental protection
ZF-10 catalyst does not contain heavy metals and harmful substances, and meets environmental protection requirements. Its low volatile organic compounds (VOC) content reduces the impact of coatings on the environment and human health during use.
2. The mechanism of action of ZF-10 catalyst
2.1 Catalytic Curing
ZF-10 catalyst accelerates the cross-linking reaction of resin and curing agent in the coating to promote rapid curing of the coating. This catalytic curing mechanism allows the coating to form a dense protective film in a short period of time, effectively preventing the invasion of corrosive media.
2.2 Enhance adhesion
ZF-10 catalyst reacts chemically with the resin and curing agent in the coating to form stable chemical bonds. This chemical bond enhances adhesion between the coating and the substrate, preventing the coating from peeling off and bubbles.
2.3 Improve durability
ZF-10 catalyst enhances the durability of the coating by forming stable chemical bonds. Its high activity and reactive properties allow the coating to maintain excellent corrosion resistance in harsh environments.

4.2 Construction technology
4.2.1 Surface treatment
Before coating, the surface of the hull needs to be thoroughly cleaned and rust-removed to ensure that the surface is free of oil stains, rust and impurities. Common surface treatment methods include sandblasting, pickling and mechanical grinding.
4.2.2 Paint preparation
Mix epoxy resin, curing agent, ZF-10 catalyst, filler and solvent in accordance with the formula ratio to ensure that the paint is free of bubbles and particles.
4.2.3 Painting construction
The coating is evenly applied to the surface of the hull by spraying, brushing or roller coating. During the coating process, the thickness and uniformity of the coating must be controlled to avoid sagging and missed coating.
4.2.4 Curing and Curing
After the coating is completed, curing and curing must be carried out under appropriate temperature and humidity conditions. The addition of ZF-10 catalyst can significantly shorten the curing time, and usually a dense protective film can be formed within 2-4 hours.
4.3 Anti-corrosion effect
The application of ZF-10 catalyst in marine anti-corrosion coatings has significantly improved the corrosion resistance of the coating. Its high activity and reactive properties allow the coating to form a dense protective film in a short period of time, effectively blocking the invasion of corrosive media such as seawater, salt spray and microorganisms.
