Antistatic coating for elastomers

What is electrostatic discharge (ESD)? 

Electrostatic discharge is a by large potential difference in an electrically insulating material emerging spark or breakdown, which causes a very short high electric current pulse. Potential difference is usually caused by static electricity.

Rhenotherm Mini Parts® has developed with

Rhenolub MK I RB 30 HD

a coating of elastomers which is electrostatically dissipative. This coating can be applied to all types of elastomers (such as EPDM, NBR, etc.), without affecting the elasticity of the components, as in commercially available conductive coatings.

Prevention of static electricity

Electrostatic discharges are prevented by the conductive connection of all metal parts and by the incorporation of metallic conductors. These are materials whose electrical conductivity is slightly increased by additives. They conduct charges resulting from safely and prevent high-current discharges. Our electrically dissipative coatings can be used for protection against electrostatic charging and deflagration.

Typical causes electrostatic charge

  • Friction of various materials with each other
  • Transferring bulk solids and liquids
  • Separating two films
  • Running on a plastic carpet

Electrically conductive coating.

According to EN 13463-1, it is assumed that an electrostatic charge is prevented when the surface resistance <= is 109 ohms.
