Long-lasting protection of low viscosity odorless amine catalyst Z-130 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 low viscosity odorless amine catalyst Z-130 in marine corrosion protection 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. Overview of low viscosity odorless amine catalyst Z-130

1.1 What is low viscosity odorless amine catalyst Z-130?

Low viscosity odorless amine catalyst Z-130 is a highly efficient amine catalyst, mainly used in the curing reaction of polyurethane coatings, epoxy resin coatings and other systems. Compared with traditional amine catalysts, Z-130 has significant advantages such as low viscosity, odorlessness, and environmental protection, and is especially suitable for odor-sensitive marine coating application scenarios.

1.2 Main features of Z-130

Features	Description
Low viscosity	Easy to mix with other coating ingredients and improve construction efficiency
odorless	Reduce odor stimulation during construction and improve the working environment
Efficient Catalysis	Accelerate the curing of the paint and shorten the construction cycle
Environmental	No volatile organic compounds (VOCs), meet environmental protection requirements
Weather resistance	Stable catalytic performance can be maintained in harsh environments

2. Advantages of Z-130 in ship anti-corrosion coatings

2.1 Improve the adhesion of the paint

Z-130 can effectively promote the chemical reaction between the coating and the metal substrate and enhance the adhesion of the coating. This is particularly important for ship coatings, because ships will be subjected to external forces such as wave impact and temperature changes during navigation. Paints with strong adhesion can better resist these external forces and prevent the coating from falling off.

2.2 Accelerate coating curing

Construction of ship coatings usually needs to be completed in a short time to minimize ship mooring time. High-efficiency catalysis of Z-130The effect can significantly shorten the curing time of the paint and improve construction efficiency. For example, the curing time of coatings using Z-130 can be reduced by more than 30% at room temperature.

2.3 Enhance the corrosion resistance of coatings

Z-130 not only accelerates paint curing, but also enhances the corrosion resistance of the paint through its unique chemical structure. Experiments show that the corrosion resistance time of coatings using Z-130 in salt spray tests is more than 50% longer than that of traditional coatings.

2.4 Improve the construction environment

Traditional amine catalysts usually have a harsh odor, which is not conducive to the health of construction workers. The odorless properties of Z-130 significantly improve the construction environment, reduce discomfort among construction workers, and improve work efficiency.
