Zincofix®

Zincofix® ® consists of a high pureness zinc-tape (> 99,95% of the chemical mass of zinc) with a nominal thickness of 0,08 mm. This tape is supplied with a 0.025 mm thick adhesive, which can resist continuous operating temperature of 80° C and which reacts under electro-conductive pressure. The adhesive layer is covered by a siliconised paper, which protects the band from getting damaged or polluted until the tape is applied.

The product is available in two forms:

  • shapes, based on the client’s needs
  • rolls, whose width from 10 to 700 mm and length 50 m
  • thickness from 0,08 to 0,45 mm

Technical description

Zincofix® is designed to cover the surface of iron, steel, aluminium and light metals in order to protect them from corrosion. This is achieved by pressing it on the surface that needs to be protected from corrosion. This method is commonly known as “Laminar Zinc Coating” The adhesive coat, which is applied only on one side of the Zincofix®, consists of a matrix of adhesive and a percentage of zinc powder. Through the addition of zinc powder and particular additives we have achieved the most important effect, which is making the adhesive itself electro conductive. This process allows the adhesive to create an electrical couple between the surface that needs to be protected and the Zincofix®, so that the zinc can act as galvanic anode.

As a consequence of the unique manufacturing process and the high pureness of the employed zinc, the band has an absolutely homogeneous and isotropic microstructure, which cannot be found in other protection systems. For this reason, any pitting or any form of local corrosive attacks are avoided
Therefore we can state that, owing to the following features:

  • stopping any direct corrosion;
  • active anticorrosive protection thanks to the electrical contact between the surface to be protected and the zinc layer, which, in the presence of an electrolyte, reacts as a sacrificial anode;
  • presence of an adhesive layer, anchored on the surface to be protected, which is an additional defense against corrosion.

The coating with our zinc layer assures a cathodic protection of metallic surfaces for a time, that, in most cases, is equal or longer than the lifetime of the structure to be protected.

Coupling steel – Light Alloy

The point of contact between light alloys and iron materials can be subjected to corrosion.

Through our zinc coating on the iron surface passive and active protections can be achieved:

  • a passive protection due to the homogeneity and isotropy of the coating and to the adhesive, which sticks well avoiding infiltration
    infiltrazione sotto pellicolare;
  • an active protection because the difference of potential between the two surfaces decreases. The potential of zinc is very similar to that of the light alloy and so the Zincofix® is the sacrificial anode instead of the light alloy.

Zincofix® tape must be stuck to the nobler metal. Should there be doubts concerning the electrolytic potentials of the materials, it is advisable to cover both the surfaces with the Zincofix® , so that any corrosion attack can be avoided.

Application fields

Automotive Protection of window borders, chassis, roofs and other areas where water can seep through. For hinges and car doors or other particular hot spots Zincofix® can offer special shapes based on the client’s needs and made on purpose to avoid corrosion problems.
