DuPont SILVADUR Silver Ion Antimicrobial Agent (SILVADUR)

Advanced, sustainable, microbial control

Although antimicrobial agents have been around for many years, they lack reliable effectiveness and consistent durability against the odors produced by microorganisms in textiles. SILVADUR antimicrobial agents feature "smart" microbial control capabilities.

SILVADUR (Xian Protective Shield) utilizes patented controlled-release technology to deliver low-concentration silver ions to the fabric surface, thereby controlling the growth of bacteria that cause odors.

DuPont SILVADUR 930 Silver Ion Antimicrobial Agent is a revolutionary microbial control technology. It utilizes a patented intelligent silver ion controlled-release technology to deliver low-concentration silver ions to the fabric surface and activate them in the presence of harmful bacteria, effectively killing and inhibiting bacteria that cause fabric fibers to produce odors, decay, and rot. This new system controls the release of silver ions, preventing the fabric from yellowing or fading. When applied during the manufacturing process of industrial and household materials, SILVADUR 930 inhibits the growth of microorganisms, providing protection, durability, and purification.

Smart Control: Silver ion release is adjustable, enhancing durability.

Excellent durability: Longer-lasting effect, enhancing cost-performance ratio

New liquid formulation: Clean and non-greasy, easy to dilute, mix, and apply.

Broad-spectrum activity: Controls various microorganisms that produce odors

Color stability: The product's quality and appearance are superior compared to other silvering agents.

Good heat stability

Easily used for natural and synthetic fibers

Excellent compatibility with a wide range of textiles and non-woven auxiliaries, including fluorochemicals, softeners, and anti-wrinkle resins.

Maintain the fabric's aesthetic appeal

The process of cold rolling and exhaustion can both be utilized.

DuPont's SILVADUR silver ion antibacterial agent provides three mechanisms of action to control odors:

Antimicrobial Odor Control

The intelligent release control conveying system utilizes an extremely low silver content (e.g., 30PPM silver particles) to control odor-causing microorganisms.

Odor Absorption and Control

Block some odor substances through absorption.

Metabolic Enzyme Controller

SILVADUR (Silver Ion Polymer) rapidly inhibits various enzymes, preventing the formation of smelly compounds like isovaleric acid (common in foot and armpit odor).

SILVADUR (Xian protective shield) provides performance at every stage of the supply chain.

SILVADUR (Xian Protective Shield) brings intelligent performance to every link of the supply chain. Textile manufacturers can create antibacterial protective products with low-dose and easy-to-use formulations.

Brand owners and retailers can design products that incorporate genuine smart freshness technology, ensuring they remain active after multiple washes. Consumers will feel more confident knowing their clothing provides smart freshness protection without harming them or the environment.

Ease of use

DuPont's SILVADUR silver ion antimicrobial agent is a solution for traditional yet often costly and problematic silver particle technology. With its aggregation properties, low-dose characteristics, and formulation composition, SILVADUR is widely chosen to replace granules, ZPT, and QUAT technologies, and is easy to use.
