Pemsa Rejiband Black C8 High Resistance Protection for Aggressive Environments

 Pemsa has developed a high resistance coating for rejiband® wire mesh tray which provides an excellent resistance to corrosion in wet and aggressive environments. It presents the following advantages

 Demonstrated with more than 1,000 hours in the neutral salt spray tests and obtained through a new manufacturing process that improves both the barrier effect against the aggressive media and the ability of self healing in damaged areas.

With the result obtained in the neutral salt spray test, more than 850 hours, the corrosion resistance is classified as Class 8, according to Table 9 of the current standard BS EN 61537 trays


High Corrosion Resistance

Hot dip galvanised normally ranges from between 45 to 70 microns mean coating thickness, so it should be Class 5, 6, or 7, having a lower corrosion resistance than BLACK C8


2. Increased capacity for selfhealing, or self-repairing, of the protective layer.


The characteristics of self-healing, or self regeneration, on scratches, minor defects or in the cutting of the wire, are remarkably better than that of the zinc


3. Aesthetic appearance.

The smooth finish is much more aesthetic than that of hot dip galvanised.

  • No sharp edges or ends.
  • No irregularities or areas with reduced thickness.
  • Black colour provides excellent aesthetics which are suitable for decorative applications, commercial facilities, false ceilings, etc.


4. Electrical continuity.

This coating maintains the electrical continuity of rejiband®, complying with the requirements of BS EN 61537 standard for cable tray system with electrical continuity characteristics.


5. Environmentally Friendly.

The BLACK C8 coating is manufactured in a process which significantly reduces energy consumption and waste generation over other coatings which consume more resources like Hot dip galvanised


6. Applications.

Suitable for cable management installations in Tunnels, Outside installations such ase Photovoltaic plants, Industry and Data centers


The most appropriate coating for Data Centers.

BLACK C8 coating avoids the emergence of the phenomenon of Zinc Whiskers, or loosening of filaments of zinc, which can be a serious problem within the electronics of clean rooms in Data Processing Centers.
