Activator Powder refers to an "Acid Salt Activator Powder." It is dissolved in water to replace the use of harsh liquid acids (such as sulfuric acid or hydrochloric acid) in the surface preparation step before the actual plating process.

    Here are the key properties of Activator Powder in precious metal plating:

• Removes thin oxide films from the base metal (substrate) such as silver, copper, brass, or nickel quickly and thoroughly.
• Eliminates alkaline residues, soap films, or chemical traces left over from the electro-cleaning stage, ensuring a pristine metal surface ready to receive the precious metal layer.

• Enhances adhesion: Prevents the plated layer from peeling, flaking, or blistering, which is critical for high-value jewelry plating.
• Ensures uniformity: Opens up the metal surface for better ion exchange, resulting in a smooth, uniform coating of gold or silver across the entire piece.

• Some formulations contain surfactants that leave the workpiece clean, bright, and sludge-free after dipping. This enhances the final brilliance of the plated gold or silver, preventing tarnish or white haze beneath the plated layer.

• Safer for operators: Reduces the risk of acid splashes and harsh fumes compared to liquid sulfuric acid.
• Buffered system: Controlled activation gently prepares the surface without over-etching or damaging the intricate, fine details of jewelry designs.
• Extended bath life: The solution derived from the dry acid salt has a high tolerance for contamination, reducing the frequency of bath replacement.
