Product Description

Salt A for Gun-color(black pearl) Electroplating

PROPERTIES

An elegant and unique Gun-color deposit can be obtained on the bright Nickel layer. At present, it is popular on the international market, widely used on light industrial products, such as watches, lamps, leather decorations and so on.

The deposit has good hardness and resistance to abrasion.

The technique is stable, suitable for both rack- and barrel-plating

TECHNIQUE FORMULATION AND OPERATING CONDITION
Potassium Pyrophosphate K4P2O7	200~250g/L
Gun-color plating Salt A	25~30g/L
Gun-color Agent B	35~40g/L
Gun-color Stabilizer	1~2g/L
Temp.	40~45°C
PH	8.5~9.5
Anode	Graphite
Dk	0.1~2A/dm2
Cathode replacement	Required

BATH MAKE-UP

1 Dissolve potassium pyrophosphate in water of 1/2 total volume, heat it to 50°C.

2 Add salt A into above solution and agitate it to completely dissolve.( it will take long time because of slowly dissolution)
3 Add agent B and stabilizer, agitate evenly, then eletrolysis for several hours, try plating.

TECHNIQUE FORMULATION FOR PASSIVATION

Chromic acid	50g/L
Temp.	Room temp.
Time	20~30s

BATH MAINTENANCE

1. The technique is stable, periodic analysis is made for daily maintenance and adjust K4P2O7 content, replenish replenishing agent of salt A and agent B according to the consumption.

The consumption as follows:
Replenishing agent of salt A	4kg/KAH
agent B	2kg/KAH

2.Because the Gun-color deposit is obtained on bright nickel or other bright deposit, bright nickel deposit must be very bright, when malfunction occurs, it is checked first. Narrow range of brightness will produce because salt A is not fully dissolved, it leads to problems coming from newly-prepared bath. Please pay attention to that.

During production, pay attention whether technique condition is among its scale, PH value is not permitted below 8.5, if so, K4P2O7 hydrolyses easily, adjust PH value with acetic acid or potassium hydroxide.
Bath must be filtered once every month and treated by activated carbon every half a year.

NORMAL PROBLEM AND REMEDY

Normal malfunction	Cause	Remedy
	too low temperature	heat
Light color	few salt A	replenish

	no enough brightness at the	enhance brightness
	bottom layer
Uneven color, narrow range of	no enough agent B	replenish
brightness	no enough K4P2O7	replenish
	too low PH	increase

	no enough stabilizer	replenish
	influence from metal impurities	electrolysis with low current
Stripe
Stripe	no enough agent B	replenish
	no enough agent B	replenish
