ZINC FLAKE
Application on coating fields: In terms of electrochemistry, zinc has a lower negative potential than iron basis and in a dielectric it is converted to a solution so that the iron basis is protected. This is especially true if the coating is damaged and the metal basis is exposed; Sealing and leakproofness : due to the corrosion reaction product of zinc powder (mainly as basic zinc carbonate, 2ZnCO3,3Zn(OH)2) deposited between the zinc powder particles, and filled into the gap between the pigments, and it is not conductive, thus sealing the coating; Shielding effect: due to the flake zinc powder is arranged parallel to the surface of the coating film in the coating, and overlapping and interlacing each other, greatly increasing the distance of water and the corrosive medium for penetrating the coating to increase the corrosion resistance of the coating.
