SILVADUR Antimicrobial Outperforms Alternative Treatment Systems
The unique technology system found in SILVADUR long lasting antimicrobial is the only credible and reliable alternative to the traditional – and, often costly and/or problematic - use of silver particle-based technologies.
The SILVADUR Advantage vs. NANO
- SILVADUR antimicrobial is a homogenous mixture containing fully soluble silver ions and fully soluble polymer in a mixture of water and/or ethanol. The silver component is not present as detectable individual metal particles of any size, but rather as dissolved chemical ions.
- What does this mean? A simple way to think of it would be to imagine an aqueous solution containing sodium and chloride ions (this could be easily prepared by dissolving table salt in water). No solid particles of table salt remain in this situation, as no solid particles of silver are present when using SILVADUR antimicrobial.
A nano antimicrobial maintains and utilizes silver metals… or, you may think of it as the table salt not dissolving in water.
The SILVADUR Advantage vs. Silver Chlorides & Particle Based Delivery Systems
Traditional silver-based antimicrobial systems rely on the delivery and presence of silver particles on the fabric surface and depend on either silver leaching to control bacteria, or insoluble silver salts to release the silver. However, due to the particle size, many of these systems cause fabric discoloration and reduced antibacterial activity over time. In addition, the particulate nature of these products results in a non-uniform antimicrobial finish, meaning a higher effective cost-to-treat. All products that rely on this approach use solid materials, this often means limited applicability across the textile supply chain due to formulation difficulty.
The SILVADUR Advantage vs. Polymeric Quat Systems
You may also observe a SILVADUR antimicrobial advantage during the application process. Products treated with SILVADUR antimicrobial require less heat, less time, and no extra binders. Polymeric quat systems are difficult to control and require careful dilution, formulation and processing conditions. And, with the structure of the polymeric quat systems, fabrics become water repellent. This makes it difficult for manufacturers meeting the needs of customers requiring moisture management capabilities. More chemicals – and more expense – are needed to control hydrophobicity inherent in polymer quat systems.
