Addplate™ and NiPlate™ 150 
A MATTE FINISH, LEAD AND CADMIUM FREE, MEDIUM PHOSPHOROUS, ELECTROLESS NICKEL PLATING PROCESS
The 150 system is an economical, matte finish electroless nickel process designed to deposit a uniform, nickel-phosphorous alloy onto a great variety of metals, alloys, and non-conductors. The 150 system is free of lead and cadmium and has been a reliable process since 1977.
The 150 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™ 150 option is supplied in three liquid concentrates: NiPLATE™ 150 A and 150 B are used for make-up, and NiPLATE™ 150 A and 150 C are used for replenishment.
- The ADDPLATE™ 150 option is supplied in two liquid concentrates: ADDPLATE™ 150 M is used for bath make up with standard nickel sulfate and sodium hypophosphite commodities, and ADDPLATE™ 150 R is used for replenishment of the bath with the same standard nickel sulfate and sodium hypophosphite commodities.
Some advantages of the 150 system are: matte deposit, high speed, ease of use, improved corrosion resistance, ammonia free make-up, excellent stability, long bath life, and consistent plating rate. The 150 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.
