EPT Coating
The environmentally friendly EcoProTeQ technology (EPT) from KMC protects chains against corrosion for twice as long as conventional rust protection, setting a new standard. Each component of every chain link is treated separately with EPT. This means a 100% coating that offers the lowest possible attack by water, salt, and air humidity.
Another characteristic of EPT: The very smooth surface gives chains excellent running qualities. Dirt buildup is minimised in the long term, which means that chain maintenance is significantly relieved.
