[nanoPost] Anti-microbial surface technologies

Anti-microbial surfaces gain more and more importance, especially facing the fact that global diseases very often are spread by contact with contaminated surfaces. Two effects are important for achieving a controlled and long-lasting anti-microbial behavior: The surface has to be anti-adhesive (easy-to-clean) and has to show a controlled release behavior over the required time of anti-microbial components. For practical uses, this type of surface has to be resistant against mechanical impacts and must not lose its properties even under heavy mechanical stress.

The company now has the technology available, which is based on the resistance of polymer nanomicro composites, which are non-silicate and non-sol-gel derived systems, available with different polymer ­bases, epoxy based, polyurethane based and polyamide based, to be tailored for a broad scale of application cases.

Depending on composition, temperature stabilities up to 300°C and Taber Abrader values of less than 1 mg weight loss after thousand cycles were obtained. No change in the anti-adhesive properties takes place after the mechanic impact. Especially the combination of easy-to-clean with controlled release of anti-microbial components leads to the superior anti-microbial behavior even under heavy duty conditions.
