Acrylic ester special monomers are common special monomers in water-based industrial paints, including methyl acrylate, ethyl acrylate, etc.

With the increasing awareness of environmental protection and attention to human health, water-based industrial paint has become the mainstream choice in the market. In water-based industrial coatings, special monomers are a crucial component. This article will introduce the types of special monomers for water-based industrial paints and their applications in the field of water-based industrial paints.
1、 Types of special monomers for water-based industrial paint
1. Acrylate special monomers
Acrylic ester special monomers are common special monomers in water-based industrial paints, including methyl acrylate, ethyl acrylate, etc. This type of special monomer has good curing performance and weather resistance, which can improve the hardness and wear resistance of water-based industrial paint, while also providing good glossiness and surface smoothness.
2. Special monomers for epoxy resins
Epoxy resin special monomers are another commonly used water-based industrial paint special monomer, which has strong adhesion and chemical corrosion resistance. By adding special monomers such as epoxy resin, water-based industrial coatings can achieve better waterproof, anti-corrosion, and wear resistance, suitable for metal surfaces that require long-term protection.
3. Polyurethane special monomers
Polyurethane special monomers have good flexibility and elasticity in water-based industrial paints, which can effectively improve the impact resistance and scratch resistance of metal surfaces. In addition, polyurethane special monomers can also enhance the yellowing resistance of water-based industrial coatings and prolong the service life of metal surfaces.
2、 The role of special monomers in waterborne industrial paint
1. Improve the adhesion of coatings: The addition of special monomers can enhance the adhesion between coatings and metal substrates, improve the adhesion and wear resistance of coatings.
2. Adjusting the rheological properties of coatings: Special monomers can adjust the rheological properties of coatings, improve their construction performance and surface smoothness.
3. Improving the weather resistance of coatings: By selecting appropriate special monomers, the UV resistance, water resistance, corrosion resistance, and other properties of water-based industrial coatings can be enhanced, extending the service life of the coatings.
3、 Case study of special monomers for water-based industrial paint in practical applications
Taking epoxy resin special monomers as an example, by improving water-based industrial paint, anti-corrosion coatings with wear resistance, weather resistance, and chemical corrosion resistance can be prepared, which are widely used for surface protection of metal structures such as ships, bridges, and oil tanks. Polyurethane special monomers can be used to prepare efficient metal primers, providing good sealing effects and surface smoothness, effectively protecting the internal structure of the metal surface.
4、 Development Trends of Special Monomers for Waterborne Industrial Paints
With the continuous improvement of people's requirements for the performance of water-based industrial paints, the development trend of special monomers for water-based industrial paints in the future will mainly be reflected in the following aspects:
1. Environmental friendliness: Green environmental protection has become a development trend in the paint industry, so the future research and development direction of water-based industrial paint special monomers will pay more attention to environmental performance and reduce the emission of volatile organic compounds (VOCs).
2. Multifunctionality: In the future, water-based industrial paint special monomers will have more versatility, which can not only improve the performance of the coating, but also achieve other functions such as antibacterial and self-cleaning.
3. High performance: With the advancement of technology, special monomers for water-based industrial paints will develop towards high performance in the future, including improving the wear resistance, weather resistance, and chemical corrosion resistance of coatings.
Summary: As an important component of waterborne industrial paint, special monomers play a crucial role in improving coating performance and functionality. With the continuous progress of science and technology, the research and application of water-based industrial paint special monomers will bring more innovation and development to the coating industry, providing more choices and possibilities for the decoration and protection of metal surfaces.
