Product Description

Plastic electroplating reducing agent

PL-3 plastic plating neutralizer


1. Said Ming 


As we all know, after the coarsening of chromic acid and sulfuric acid, chromic acid has serious harm to each electroplating step. PL-3 is a unique liquid mixed solution with good chromium capacity and fast reduction speed. This process is used to neutralize the hexavalent chromic acid staying on the surface of the workpiece and hanger.

2. Characteristics and uses


1. Capable of remaining in the workpiece and rack fracture of hexavalent chromium also the original to trivalent chromium, with a plating efficiency to reduce a leak phenomenon due to the contamination caused by hexavalent chromium ;

2. Prevent the chemical solution in the subsequent process from being contaminated by hexavalent chromium and damage its function, which can reduce the consumption of palladium water.

3. Improve the adhesion of the coating.

3. Solution composition and operating conditions



Pure water


Reagent hydrochloric acid 37%

80-120 ml/L

100m l/L



When the room

0.5 - 10 mins

3 - 5 mins

temperature 30 - 65 [deg.] C

60 - 65 [deg.] C






The set apparatus 



Polyethylene resin, PVC , ceramic equipment, high-density polyethylene, polypropylene, heat-resistant glass


Mild to strong air stirring (using a filtered low-pressure fan)


Not needed


Recommended to use


Teflon, quartz


5. Preparation method


1. Deionized or distilled water thoroughly cleaned with a cylinder groove;

2. In the tank by adding 3/4 volume of distilled or deionized water;

3. 10% by volume of hydrochloric acid (reagent grade 37%), while slowly stirring the solution should be, noted that no hydrochloric acid was dissolved before adding not uniformly PL-3 ;

4. Adding 1-2% by volume of the PL-3 to the tank ;

5. Adjust to the final volume with deionized water;

6. heating the solution to a desired temperature ;

6. Maintenance control 


1. the workpiece should be thoroughly cleaned after before can enter the PL-3 working solution, the solution should have a moderate air agitation, air agitation is highly recommended and may enhance the ability of the solution. Note: The best plastic parts should be soaked for 3 minutes, and the foam plastic should be soaked for 5 minutes. Workpiece should be cleaned thoroughly at least two times before they can enter the PL-3 working solution.

2. The operating solution can maintain normal production by supplementing reagent grade 37% hydrochloric acid and PL-3 .

3. The analysis method provided by Bigley can be used to control the solution .
