Addplate™ and NiPlate™ 200

A CORROSION RESISTANT, NON-MAGNETIC, HIGH PHOSPHOROUS ELECTROLESS NICKEL PLATING PROCESS

The 200 system is an economical, corrosion resistant high phosphorous electroless nickel process designed to deposit a uniform, nickel-phosphorous alloy onto a great variety of metals, alloys, and non-conductors.

The 200 system is available in two packaging options to best meet your needs. The NiPLATE™ option provides the greatest convenience to the user, while the ADDPLATE™ option provides the greatest economy for shipping and use. Both options produce the same properties and quality.

  • The NiPLATE™ 200 option is supplied in three liquid concentrates: NiPLATE™ 200 A and 200 B are used for make-up, and NiPLATE™ 200 A and 200 C are used for replenishment.
  • The ADDPLATE™ 200 option is supplied in two liquid concentrates: ADDPLATE™ 200 M is used for bath make up with standard nickel sulfate and sodium hypophosphite commodities, and ADDPLATE™ 200 R is used for replenishment of the bath with the same standard nickel sulfate and sodium hypophosphite commodities.

Some advantages of the 200 system are:

  1. Corrosion resistance in acid environments
  2. Neutral salt spray resistance of 1000 hours
  3. A semi-bright deposit that will pass the nitric acid test
  4. A pit free deposit of 5 mils or more
  5. Excellent stability and bath life
  6. Compressive stressed deposit
  7. Non-magnetic properties

The 200 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.
