Addplate™ and NiPLATE™ 700
A COMPOSITE SILICON CARBIDE, MEDIUM PHOSPHOROUS,
ELECTROLESS NICKEL PLATING PROCESS
The 700 system is a composite silicon carbide, electroless nickel process designed to deposit a uniform composite with ultra-fine silicon carbide particles onto a great variety of metals, alloys, and non-conductors.
The 700 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™ 700 option is supplied in four liquid concentrates: NiPLATE™ 700 A, 700 B, and 700 D are used for make-up, and NiPLATE™ 700 A, 700 T, and 700 D are used for replenishment.
- The ADDPLATE™ 700 option is supplied in three liquid concentrates: ADDPLATE™ 700 M is used for bath make-up with NiPLATE™ 700 D and standard nickel sulfate and sodium hypophosphite commodities, and ADDPLATE™ 700 R is used for replenishment of the bath with NiPLATE™ 700 D and the same standard nickel sulfate and sodium hypophosphite commodities.
Some advantages of the 700 system are:
- Deposits with exceptional wear resistance surpassing chrome plating
- Corrosion resistance
- High plating rate
- Excellent stability and bath life
- Self-adjusting bath pH
- Ease of use comparable to conventional electroless nickel
The 700 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.
