Cyanide Bright Zinc Process , Zinc electroplating , Cyanide zinc plating JZ-2
Properties
• liquid brightener
• produces brilliant deposits at low, medium, and high current densities
• for both barrel and rack operations
• excellent throwing and covering power
• plated parts can easily be chromated
• due to the variable metal and cyanide content of the solution, it may be usedover a wide range of operating conditions
• contains no aldehydes - a fact which allows the plater to use operating temperatureshigher than normal (up to 45 °C)
• its brilliant deposits and its economic use make it the outstanding cyanide zincbrightener system
