CovaClear™ 

Dual Antimicrobial Silicone Adhesive by Covalon Technologies Ltd.

Covalon’s patent pending dual antimicrobial clear silicone adhesive film technology CovaClear™ combines silver and chlorhexidine right in the adhesive, providing superior comfort and protection throughout. The CovaClear™ technology boasts broad spectrum antimicrobial activity of at least 7 days and meets the current FDA standards for antimicrobial claims of a “greater than 4-log reduction”. CovaClear™ remains transparent for up to 7 days, allows longer site visualization and has the potential to reduce frequent and costly dressing changes. The soft skin silicone adhesive is comfortable to wear, and has been proven to cause less irritation to the skin and significantly less painful upon removal versus products using acrylic adhesives.

FIGURE 1: 

The rapid antimicrobial activity of CovaClear™ is clearly demonstrated by the log reduction data of Figure 1. When challenged with approximately one million microorganisms from eight common pathogenic microbes, CovaClear™ was able to kill on average 99.9% of the inoculum within 10 minutes and 99.99% after 30 minutes of contact time. All microorganisms reached a 4 log reduction or greater by 6 hours - which was maintained for the remainder of the 7 day study.* The reduction value represents essentially a complete eradication of the initial microbial challenge.
