Invention Summary

chemistry

This invention pertains to the development of stable polymeric anti-fouling surface coating formulation that contains Quaternary Ammonium Salts (QAS) as the primary disinfectant.

Benefits

Biocidal activities have been shown on a range of bacteria, diatom and yeast cultures. These coatings are found to be stable after water immersion.

Invention Premise

The quarternary ammonium salt forms a cross-linked network structure with trimethoxy groups in silanol terminated poly-dimethylsiloxane, where the salt is chemically bonded in the network structure. Types of QASs, their levels of concentration, molecular weight of poly-siloxanes, levels of catalyst, and the amount of cross-linker are the critical determinants on the stability and effectiveness of the coating.

Patents

This technology is patented with fully preserved US patent rights (issued US patent 8,372,384), and is available for licensing/partnering opportunities.
