REAXIS® C1001 is a reducing agent that is commonly used in the manufacturing of electroplated coatings and electronic components. This compound acts as a reducing agent by donating electrons to metal ions, allowing them to be reduced to a lower oxidation state. In electroplating applications, REAXIS® C1001 is used to reduce metal ions in the plating bath, allowing for the deposition of a thin layer of metal onto a substrate. This process is used to improve the corrosion resistance and wear resistance of a wide range of metal components. In the electronics industry, REAXIS® C1001 is used to reduce metal ions during the production of printed circuit boards, where it helps to create a thin layer of conductive metal on the surface of the board.

Package & Storage
