In an emergency, rapid shutdown boxes switch off photovoltaic (PV) modules or strings in a controlled manner within a very short time, thus protecting rescue services from exposure to hazardous voltages. They also ensure the safety of employees during maintenance work. The safety-related electronic components must be able to withstand…

Humidifiers in PEM fuel cells need to withstand high levels of humidity as well as exposure to heat and chemicals. The materials used in these applications are therefore of key importance for their safe, reliable operation and efficient production. To meet the strict requirements, WEVO-CHEMIE GmbH has developed adhesives, sealants…

WEVO-CHEMIE GmbH introduces WEVOSIL 23010 and WEVOSIL 23030, two new liquid silicone rubbers (LSRs) specially developed for silicone textile coatings and sealing applications (CIPG/FIPG). Both systems combine excellent processability with high elasticity, temperature resistance and adhesion. They open up new possibilities for precise and automated manufacturing processes using dispensing on…

Transformers in rail vehicles must operate reliably under extreme conditions: voltages, vibrations and fluctuating temperatures place stringent demands on the materials used. With its specially optimised epoxy resin potting compounds, WEVO-CHEMIE GmbH offers solutions that combine long-term stability with efficient processing. The materials meet fire protection requirements in accordance with…

WEVO-CHEMIE GmbH is expanding its portfolio with the 2K silicone adhesive WEVOSIL 28015 FL. The new RTV silicone combines high thermal conductivity with structural strength and residual flexibility – properties that are crucial for modern battery modules and power electronics. This material enables automotive manufacturers and electronics producers to implement…

Currently, different concepts and materials are used for the reliable sealing of fuel cells and electrolyser stacks. These include prefabricated flat gaskets or O-rings that are predominantly manufactured by injection moulding or other moulding processes – methods that are both time- and cost-intensive. But now, coating experts Laufenberg GmbH and…
