Organic Chemicals are primarily used as wetting agents or surfactants in electroplating baths. They reduces surface tension, allowing the plating solution to spread evenly over the substrate. They also Improve the adhesion of the metal coating by ensuring uniform wetting of the surface. Moreover, they help prevent defects like pitting or uneven plating by minimizing air bubbles and improving solution flow. Inorganic phosphorus based chemicals find application as reducing agents and are particularly important in electroless plating processes. They help to reduce metal ions (e.g., nickel ions) to their metallic form, enabling deposition on the substrate without the need for an external electrical current. This enhances the corrosion resistance and hardness of the plated layer. An acetone based chemical is also used as a brightener or additive in electroplating baths, particularly in nickel plating, as it Improves the brightness and smoothness of the plated surface.
