Antibacterial agent for water-based color steel paint, long-lasting antibacterial, protecting the coating
Antibacterial agents for water-based color steel paint can achieve antibacterial effects by destroying the cell structure or metabolic process of microorganisms. Common types include organic, inorganic and compound antibacterial agents. When choosing, comprehensive considerations should be given to anti-corrosion performance, safety, stability and compatibility with the paint body. The following is the specific introduction:
Mechanism of action
The antibacterial agent for water-based color steel paint mainly achieves the effect of anti-mold and antibacterial by destroying the cell walls and cell membranes of microorganisms and interfering with their metabolic processes. Some antibacterial agents can also form a protective film on the surface of the paint film, preventing the invasion of mold and bacteria.
Common types
Organic antibacterial agent
Features: It has highly efficient anti-mold and antibacterial properties, but it may have certain pungent odors and toxicity issues. Some organic antibacterial agents, such as isothiazolinone, can remain stable within a wide pH range, are not volatile, and provide long-lasting protection for coatings.
Application: Widely used in fields such as architectural coatings, industrial coatings, wood coatings and automotive coatings, including water-based color steel coatings.
Inorganic antibacterial agent
Features: It inhibits the growth of mold and bacteria by releasing metal ions, featuring long-lasting and stable effects, and has a relatively small impact on the human body and the environment. However, the price is relatively high, the production process is complex and the effect is slow.
Application: Suitable for water-based color steel paint systems with high requirements for environmental protection and safety.
Compound antibacterial agent
Features: It combines organic and inorganic antibacterial agents, integrating the advantages of both to enhance the anti-mold and antibacterial effects as well as stability. This type of antibacterial agent usually has broad-spectrum antibacterial properties and can effectively combat various molds and bacteria.
Application: Suitable for water-based color steel paint systems that require efficient and broad-spectrum antibacterial performance.
