ZINC PLATED
C4 EVO COATING Is a multilayer coating composed of: • An external functional layer of epoxy matrix with aluminium flakes of around 15-20 μm, which gives the coating optimum resistance to mechanical and thermal stresses. The aluminium flakes also serve, when required, as sacrificial cathodes for the metal base of the screw. • A central binding layer for the external functional layer. • An internal layer of around 4 μm zinc microns which acts as an additional layer of corrosion resistance.
