SUPERIOR CORROSION RESISTANT COATING
Apart of field test which take a very long time for our more advanced coatings, the performance of a metallic coating is generally evaluated using corrosion cabinet testing. There tests are conducted is closed cabinets where the conditions of exposure are controlled and mostly designed to accelerate specific corrosion mechanisms that play. Cabinet tests are generally used to determine the corrosion performance of materials intended for use in natural atmospheres. In order to correlate test results with service performance, it is necessary to establish acceleration factors and verify that corrosion mechanisms are indeed following the same paths. The most common test referred to salt spray and kesternich.
For equal coating weight, Bekaert Bezinal 2000 corrosion resistance is approximate 6 times better than heavy galvanized wire. Bekaert Bezinal 2000 = more than 2000 hours salt spray resistance for full coat wires according to EN-10244-2 class A.
Corrosion Performance in Saltspray
(according to DIN SS 50021, ASTM B117, ISO 9227)
The salt spray test is a standardized test method used to check corrosion resistance of coated samples. The salt spray is particularly useful for detecting discontinuities such as pores and other defects in certain metallic coatings. The test is suitable to check if the comparative quality of a metallic material is maintained.
Salt spray resistance (average) – hours till 5% DBR*
Expected Lifetime in Different Corrosion Classes
(according to EN ISO 922d;1992)
The relative performance of Bekart Bezinal coatings versus zinc in these accelerated tests, combined with the specified coat weight loss per year for a zinc coating, allows to make a calculation estimation of expected lifetime in the different corrosivity classes defined in EN ISO 9223. Expected lifetime for the different coating classes and different corrosivity categories is given in the graph below. Extensive outdoor exposure programs on different Bekaert sites representing different environment corrosivity, are launched.
Expected Lifetime (average) – years until 5% DBD
The above described factors are used to define different corrosivity classes C1 to CX, these are described in the standard EN ISO 9223 and summarized in the table below. The standard EN ISO 9224;1992 defines the zinc coating loss per year for each of the corrosivity classes; this is as well mentioned in the table below.
The high-quality wire consists of a standard galvanized core wire bonded with a highly adhesive PVC coating. This particular coating technique is preceded by the application and curing of a primer followed by the application of a PVC coating.
This technology combines the typical adhesive properties of fusion bonded coatings with the surface quality of extruded wires resulting in a clean, aesthetic and crack resistant coating. thanks to these features, the PVC coated wire is ideal to be used in environments that are exposed to extreme temperatures, highly corrosive atmospheres and abrasive elements (coastal areas, deserts, etc)
- Fencen coastal areas, deserts, etc
- Slope protection
- Agricultural wire
- Superior corrosion resistance – less creeping rust that penetrates at cracked points
- Excellent cathodic protection of cut ends
- Less risk of cracking
- Smooth aesthetic coating surface
