The principle of plating sealer is mainly to realize the effect of anti-corrosion and anti-discoloration by forming a dense protective film on the metal surface. This protective film is generated by the chemical reaction between the plating sealer and the metal surface, which can effectively separate the metal from the corrosive medium, thus preventing the dissolution and corrosion of the metal.
Plating sealers are usually divided into two types: water-based and oil-based. Water-based sealer to water as a solvent, with environmentally friendly performance, does not contain formaldehyde, benzene and other harmful substances, the treated metal surface has excellent corrosion resistance and brightness.
In addition, the plating sealer can also improve the corrosion resistance of the plating layer, usually can make the corrosion resistance of the plating layer to improve more than 3-5 times.
In practical application, plating sealer is often used to improve the gold and chrome imitation, copper alloy, silver, nickel and other plating layer of the anti-color ability, after treatment of the workpiece with anti-blue point, anti-salt spray, anti-sulfuration and other characteristics. These characteristics make the plating sealer has a wide range of application value in industrial production.
