Additional information
CresaCoat® dry coating is a non-electrolytically applied, thin coating with integrated lubricating properties and additional corrosion protection. Certificate is available on request for specific properties such as friction coefficients. For fasteners with a tribological coating, it is essential to clarify the requirements in advance, in particular a validation of the friction values is required for nominal dimensions > M12!
