Corten A,Corten B Weathering treatment

Corten A Corten B process of weathering is the first clean the surface of Corten-A steel material, and then spray a layer of weathering solution (weather coat solution), and some of the chemical elements of the surface of the Corten-A produce electrochemical reflect, to form a layer of Cu, P, Cr, Ni Fe oxide membrane.

And then Corten A steel plate spray a layer of prepalene, prepalene is a mixture of colors, including low molecular weight acrylic resin (acrylic resin and organic solution. Because prepalene is highly hygroscopic and infrared absorbing ability, it can accelerate the formation of solid oxide film.

After a period of time, that is enough to protect the Corten-A steel is no longer continue to corrosion.

Corten-A after weathering treatment, that has the following advantages:
1. because the generated solid oxide film, so there is no rust flaking, so as to avoid the pollution problem.
2. the surface is quite smooth.
