CU-500 is a copper etching agent formulated with special organic substances.
On the surface of copper products, an oxide film is generated according to the environment during various processing stages. The product demonstrates its processing capability with only a short immersion, significantly enhancing the stability with the maximum advantages of water solubility, such as non-flammability, degreasing properties, and workability, without concerns about pollution or other issues.

basic information
Properties Appearance: Brown transparent liquid pH (concentrate): 1.7 ± 0.5 Specific gravity: 1.04 ± 0.01 Instructions for use: 1. Before etching, remove any oils and dirt adhering to the product surface. 2. The product can be used at a concentration of concentrate to 50% aqueous solution. 3. Use at room temperature. 4. The copper oxide film remover CU-500 roughens the copper surface, so it should be used as a pretreatment agent for metal surface treatment to enhance adhesion for plating and painting.
