The long-lasting protection of reactive low-odor amine catalyst ZR-70 in marine 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 reactive low-odor amine catalyst ZR-70 in marine anti-corrosion coatings has gradually attracted attention. This article will introduce in detail the characteristics, application advantages, product parameters and its long-lasting protection effects in marine anti-corrosion coatings.

1. Basic characteristics of ZR-70

1.1 Chemical structure

ZR-70 is a reactive low-odor amine catalyst. Its chemical structure contains multiple reactive amine groups, which can react chemically with the resin during the coating curing process to form a stable crosslinking network. This structure not only improves the mechanical properties of the coating, but also enhances its corrosion resistance.

1.2 Low odor characteristics

ZR-70 has low odor properties during production and application, thanks to the absence of volatile organic compounds (VOCs) in its molecular structure. Low odor characteristics not only improve the working environment, but also reduce the health hazards to operators.

1.3 Reactive activity

ZR-70 has high reactivity and can react quickly with resin at lower temperatures, shortening the curing time of the coating. This characteristic is particularly important in the process of ship coating, which usually needs to be completed within a limited time to improve production efficiency.

2. Advantages of ZR-70 in ship anti-corrosion coatings

2.1 Improve the adhesion of the paint

ZR-70 can form stable chemical bonds with resins, enhancing the adhesion between the coating and the metal substrate. This adhesion not only improves the durability of the coating, but also reduces the risk of coating peeling, thereby extending the service life of the ship.

2.2 Enhance the corrosion resistance of coatings

ZR-70 effectively blocks the penetration of moisture, oxygen and corrosive ions by forming a dense crosslinking network, thereby improving the corrosion resistance of the coating. This corrosion resistance is particularly important in marine environments, as salt and humidity in seawater can accelerate the corrosion of metals.

2.3 Improve the mechanical properties of coatings

ZR-70 can improve the hardness, wear resistance and impact resistance of the coating, so that it can withstand various mechanical stresses during ship navigation. This improvement in mechanical properties not only extends the life of the paint, but also reduces maintenance costs.

2.4 Environmental performance

The low odor characteristics of ZR-70 and VOC-free properties make it possible toIt becomes an environmentally friendly catalyst. During the process of ship coating, the use of ZR-70 not only reduces environmental pollution, but also complies with increasingly strict environmental regulations.

In practical applications, the anti-corrosion coating of ships using ZR-70 shows excellent corrosion resistance in marine environments and can effectively extend the service life of the ship.

4.2 Anti-biological fouling performance

Microorganisms and algae in the marine environment will attach to the surface of the hull, forming biological fouling, which not only affects the navigation performance of the ship, but also accelerates the corrosion of the hull. ZR-70 effectively reduces the formation of biofouling by improving the surface smoothness and resistance to adhesion of the paint, thereby improving the navigation efficiency and corrosion resistance of the ship.

4.3 UV resistance

When ships are exposed to sunlight for a long time during their navigation, ultraviolet rays will accelerate the aging and degradation of the paint. ZR-70 effectively delays the aging process of the paint by improving the UV resistance of the paint, thereby extending the service life of the paint..

4.4 Impact resistance

Whites will bear various mechanical stresses during their navigation, such as wave impact, collision, etc. The ZR-70 reduces the risk of coating peeling and breakage by improving impact resistance of the coating so that it can withstand these mechanical stresses.
