An experimental investigation into the effect of Cu2O particle size on antifouling roughness and hydrodynamic characteristics by using a turbulent flow channel.

An East Helena building project slated to be completed this summer will put American Chemet on track to streamline its processes and increase capacity. The company started building one large structure over the top of several existing wood structures in August 2017. 

Elementary students in East Helena will be part of an early education game to prevent suicide by reducing behavioral problems and mental health issues. Blue Cross Blue Shield and American Chemet provided almost $17,000 in grant funding to train Kindergarten through third grade teachers on the PAXIS Institute Good Behavior Game last month.

Jotun believes the European Union’s decision to approve the use of copper in marine antifoulings will ensure continued delivery of powerful benefits for both the shipping industry and environment. Copper is a key ingredient of most antifouling coatings, valued for its ability to provide the best overall balance of environmental protection and cost savings.

“Biofouling control has tremendous environmental benefits that range from energy savings to slowing the spread of invasive species. Over regulating copper-based antifouling coatings—the most proven and utilized [marine] coatings in the world, which have been universally approved by numerous countries worldwide based on the results of exhaustive human health and environmental studies—is questionable.

This article gives an updated overview of the use of copper in antifouling paints. In the first part, the worldwide regulatory status is summarized, for both commercial vessels and pleasure craft, based on the results from the detailed scrutiny of copper that has been undertaken by regula- tors in recent years in countries such as the United States, Australia, New Zealand and the EU.

Copper is used in everything from automobiles to air conditioners, but it has one property that makes it especially attractive for medical uses: It kills bacteria.
