The SILVADUR™ Advantage

SILVADUR™ Technology vs. NANO

  1. SILVADUR™ antimicrobial technology 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.
  2. 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 technology maintains and utilizes silver metals... or, you may think of it as the table salt not dissolving in water.

SILVADUR™ vs. Silver Chlorides & Particle Based Delivery Systems

Traditional silver-based antimicrobial technology 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 technology 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.

SILVADUR™ vs. Polymeric Quat Systems

You may also observe a SILVADUR™ antimicrobial technology advantage during the application process. Products treated with SILVADUR™ antimicrobial technology 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.
