Instantly remove the static film and maximize the adhesion of the plating.
The activator is an important pretreatment chemical that removes oxide films, passive films, and fine oxides or foreign substances formed on metal surfaces, significantly enhancing adhesion with subsequent processes such as plating, painting, and bonding. It demonstrates reliable and uniform treatment effects, especially on materials with strong oxide films, such as stainless steel, copper, and nickel. The Sunlight activator series offers a wide variety of options that can be selected according to the treated material, line configuration, and process conditions, including types based on nitric acid, sulfuric acid, and hydrochloric acid. It achieves stable activation of various metals in a short time, preventing issues such as poor adhesion, discoloration, and pinholes. It is adopted in various fields that require high precision and high reliability, such as electronic components, automobiles, housing equipment, communication devices, and medical sectors, and its performance is highly regarded both domestically and internationally. With a safety design that considers laws such as the Poisonous and Deleterious Substances Control Law, the Industrial Safety and Health Law, and the PRTR Law, it ensures a treatment process that is gentle on both workers and the environment.

Applications/Examples of results
Activators are essential chemicals in the pre-treatment processes of plating and painting, effectively removing oxide films, scales, and fine foreign substances adhered to metal surfaces, significantly improving adhesion with subsequent processes and uniformity of the finish. They can be used with a variety of metals such as iron, copper, zinc, stainless steel, and nickel, and by selecting powder, liquid, or electrolytic types according to the target metal and equipment conditions, efficient pre-treatment is achieved. The powder type is widely adopted in mass production lines for automotive parts and machined components, demonstrating excellent performance in wastewater treatment and cost-effectiveness. The liquid type meets the high-quality demands of electronic components, housing equipment, and precision mechanical parts, and is also effective in re-plating and low-volume, high-variety production environments. Additionally, by improving adhesion, it prevents paint film peeling and plating defects, ensuring durability and appearance quality. In numerous manufacturing sites both domestically and internationally, stable processing performance and environmental compatibility have been recognized and implemented.
