Electrically conductive coating for elastomers
What does electrostatic discharge mean?
Electrostatic discharge is a spark or breakdown resulting from a large potential difference in an electrically insulating material, causing a very short high electric current pulse. The cause of the potential difference is usually a charge due to static electricity.
Rhenotherm Mini Parts® has succeeded in using the system Rhenolub MK I RB 30 HD to develop a coating for elastomers that is electrostatically dissipative. This coating can be applied to all elastomers (such as EPDM, NBR, etc.), without affecting the elasticity of the components, as in commercially conductive coatings.

Prevention of electrostatic charge
Typical causes of electrostatic charge
Electrostatic discharges are prevented by the conductive connection of all metal parts and the incorporation of metallic conductors. These are materials whose electrical conductivity is slightly increased by additives. They safely discharge resulting charges and prevent high-current discharges.
Our electrically dissipative coatings can be used to protect against electrical charging and deflagration.
Electrically dissipative coating.
According to EN 13463-1 it can be assumed that an electrostatic charge is avoided if the surface resistance <= 109 ohms.
