Antibacterial powder coating
We are a manufacturer based in China, specializing in high-quality Antibacterial powder coating for industrial clients worldwide. Technical support and custom formulation available.
Category：Special powder coatings | Brand：MT
Introduction
Antibacterial Powder Coating is a functional powder coating formulated with an inorganic silver-ion antibacterial agent incorporated during manufacturing. It is designed to help inhibit the growth of selected microorganisms on coated surfaces. Depending on the formulation and verified test results, it may be suitable for indoor and outdoor high-touch surfaces where improved surface hygiene is desired.
How It Works
Antibacterial coatings are designed to inhibit the growth of selected microorganisms on treated surfaces. In this formulation, silver-ion antibacterial agents are incorporated into the powder during manufacturing and become part of the cured coating film. Antibacterial performance depends on the formulation, surface condition, test organism, and exposure conditions. Long-term effectiveness should be confirmed through appropriate persistence and durability testing.
Applications
Potential applications include metal surfaces and equipment that benefit from additional hygiene-related functionality:
Antibacterial Performance
The source specifications report antibacterial activity against selected bacteria and fungi, including Escherichia coli, Staphylococcus aureus, Aspergillus niger, Aspergillus flavus, Penicillium, Mucor, and common dermatophyte fungi. The reported antibacterial reduction is 4N–5N, equivalent to approximately 99.99%–99.999% reduction under the relevant test conditions. The organisms tested, test methods, contact time, and results should be confirmed against the product-specific laboratory report.
