Post-treatment Chemicals

Post-treatment chemicals are a class of chemicals used after completion of electroplated coatings. Its purpose is to further improve the corrosion resistance, decoration, and functionality of the plating layer. Usually, the post-treatment process is selected according to the performance, use requirements, environmental impact, and other factors of the plating layer. The post-treatment process for most finished surfaces includes not only simple cleaning, but also corrosion control or other protection. Common post-treatment chemicals include sealants, passivator, deplating agents, anti-discoloration agents, electrolysis protection powder, high corrosive-resistant sealer, etc. These chemicals play an important role in the post-treatment process.
