Cenospheres at Ceno Technologies - USA

Silver Coated Cenospheres

cenospheres silver coatedCeno Technologies use a patented and proprietary process of wet chemistry to coat cenospheres with a thin layer of silver that allowed the finished product to perform like silver in electrical conduction and infra-red (IR) reflection AND simultaneously perform like a ceramic in thermal insulation, low cost, low maintenance and ease of use. Silver Coated Cenospheres from Ceno Technologies are extremely reflective and can exhibit an EMI shielding effectiveness of 60dB from 100 MHz to 25 GHz and higher.

Developed to produce electrically conductive coatings which can be added to tiles, fabrics, adhesives, sealers, plastic, rubber, composite and resin materials. When added at appropriate ratios, these materials can then provide electrical conductivity and shielding of electronic devices against Electro Magnetic Interference (EMI). The low particle density and large surface area facilitates slow phase separation in paints and adhesives compared to heavy metallic and inorganic fillers.

General Information

High performance and long term conductivity due to excellent oxidation resistance.

Typical coatings from water base paints show a conductivity of 0.1 to 0.3 ohms per square, depending on thickness.
