Hex-A-Gone™ 1020 is a decorative trivalent chromium

electroplating system which produces a finish comparable in

color to a hexavalent chromium deposit. Hex-A-Gone™ 1020

offers exceptional throwing power, ease of operation, and good

tolerance to metallic impurities. Trivalent chromium plating

solutions offer reduced waste treatment costs and less health

and environmental concerns than hexavalent chromium

solutions.

• Exceptional throwing power with bright deposits at

thicknesses up to 20 microinches (0.5 microns)

• Environmentally friendly - Contains no carcinogenic

hexavalent chromium

• Higher bath efficiency produces plating rates of 2-3

microinches per minute (0.05-0.08 µm/minute)

• Improved throwing power compared to hexavalent chrome

plating allows for 30-50% increase in rack density

• Deposit color is similar to hexavalent chromium deposits

• Hexavalent Chromium-free

• Reduced energy consumption

Equipment:

Tank: A polypropylene, PVC, or Koroseal lined tank.

Anodes: Inert anodes with special catalytic coatings are used for direct contact

with plating solution. Pavco recommends installing a plastic mesh over

the anodes to prevent scratching or mechanically damaging the catalytic

coating. Contact Pavco representative for sourcing. USE ONLY PAVCO

QUALIFIED ANODE SOURCES.

Anode Bars: Use copper anode bars, preferably shielded with plastic.

pH meter: Careful control of pH is critical to the successful operation of Hex-A-Gone™

1020. A good pH probe and frequent standardization of the meter are

necessary.

Filtration: Use 5 - 15 micron polypropylene filters and activated carbon.

Filtration rate should be at least 1 tank turnover per hour.

Rectifier: Up to 12 volts, less than 5% ripple.

Temperature Control: A titanium heat exchanger is recommended.

Ventilation: Required, check local regulations

Agitation: Air agitation is required for dissolution of salt additions. Air agitation is

optional when electroplating. If air is used, it should be light and uniform.

Slow mechanical agitation with a moving cathode rod produces the most

optimal results.

Metallic Removal: Effective contaminant removal is critical to maintaining consistent deposit

color. Continuous contaminant removal is recommended by continuous

dummy cell (10% of tank volume) or ion exchange. Consult a Pavco

representative for recommendations on dummy cell design or Premier IX

Resin ion exchange resin system.

Bath Maintenance:

Hex-A-Gone™ Cr Maint.: 1 gal/4,000-8,000 amp-hrs. (475-870 mL/1,000 amp-hrs(KAH))

Rate varies with cathode efficiency. Adjust feed rate based on chrome

metal concentration. Continuous, regular additions are required, even

during dummy electrolysis.

DecoTri MS:

1 gal/ 25,000 amp-hrs. (150 mL/KAH)

Hex-A-Gone™ Salts:

Based on specific gravity (see Analytical methods) consumed by

dragout.

Hex-A-Gone™ Catalyst:

1 gal/10,000-25,000 amp–hrs. (150-400 mL/KAH). Start at 1 gal per

17,000 amp–hrs. (220 mL/KAH)

Hex-A-Gone™ 1020 Carrier:

1 gal/5,000 amp–hrs. (760 mL/KAH)

CAUTION: Careful, routine monitoring of pH is required for successful operation of Hex-A-Gone™

1020. DO NOT ALLOW THE pH TO EXCEED 3.8.

Bath Makeup per 1,000 gallons (3,785 L):

Use “General Purpose” makeup unless otherwise specified by Pavco representatives.

1. Add 800 gallons (3,000 L) of deionized water to a clean tank.

2. Heat the water to 130°F (54°C). Maintain at this temperature during make up procedure.

3. Add 2,335 pounds (1,060 kg) of Hex-A-Gone™ Salts slowly with good agitation.

4. For “High Efficiency” makeup, (9.5 g/L chrome) add 160 gallons (606 L) of Hex-A-Gone™ CR Make-

up. For “General Purpose” makeup, (7 g/L chrome) add 120 gallons (454 L) of Hex-A-Gone™ CR

Make-up.

5. After the Salts and Make-up are thoroughly dissolved, raise the solution level to 90% of operating

volume with deionized water.

6. Lower the pH of the solution to 1.8 with 50% sulfuric acid and agitate for 12 hours minimum to

establish the proper chromium complex.

7. After the 12 hour period, raise the pH over a two hour period to operating range with 45%

potassium hydroxide (low chloride grade).

8. Treat solution with 2 g/L activated carbon powder. Allow to stir for 2 hours then remove with

filter.

9. Add 12.4 gallons (46.9 L) of Hex-A-Gone™ 1020 Carrier, 1.5 gallons (5.7 L) of Hex-A-Gone™

Catalyst, 17.5 gallons (66.2 L) Hex-A-Gone™ Whitener, and 2 gallons (7.6 L) DecoTri MS.

10. Add DI water to the final volume.

11. Electrolyze the bath for a minimum of 2 amp-hours/gallon (0.5 amp-hours/L) as needed before

use. Confirm plating rate and coverage by hull cell before production use.

Operating Tips:

• Use routine additions of Hex-A-Gone™ 1020 Carrier and Hex-A-Gone™ Catalyst to maintain

good coverage, color, and thickness of the chromium deposit.

• Use routine additions of Hex-A-Gone™ Cr Maint. to maintain chromium levels. Hex-A-Gone™ CR

Make-up is normally only needed for new bath make-up or when Hex-A-Gone™ Complexor levels

are low.

• Higher chromium levels will improve the high current density range but can reduce coverage in

low current density areas.

• Use of waste treatment grade caustic is not recommended. Use caustic with a specification of

less than 50 ppm chloride (<.005%) to avoid chloride contamination issues. Chloride

accumulation can decrease life of anode coating.

• Metallic contaminants MUST BE TREATED REGULARLY. Nickel in excess of 50 ppm, zinc in

excess of 10 ppm, or iron in excess of 30ppm can reduce the bath efficiency (slow down the rate

of deposition) as well as darken the deposit. Best practice is to use Premier Ion Exchange resin.

Another option is to electrolyze the solution at 18 amps/ft2

(2 amp/dm2

) in a continuous

electrowinning cell. Total combined metallic contaminants should be kept under 50 ppm in

order to achieve “blue” color.

• Carbon filtration is recommended to maintain good color and efficiency. Use 2 - 4 pounds of

granular activated carbon (1 - 1.5 kg) per 1,000 gallons (4,000 liters) of solution. Replace the

carbon every two weeks.

• Inspect the anode coating every three months. The anodes will require periodic recoating. Thin

anode coating will result in hex chrome formation and poor chromium coverage.

• Routinely check for hex chrome to confirm proper anode coating and addition rates. Hexavalent

chrome formation can be due to poor anode coating, low Hex-A-Gone™ 1020 Carrier, or bath

contaminants.

• Keep the specific gravity below 1.26 for optimal high current density performance.

• Catalyst levels will reduce gradually during downtime. Monday morning startup typically

requires extra Hex-A-Gone™ Catalyst (0.05-0.10%) to obtain desired plating rate.

Hex-A-Gone 1020 Components and Functions:

Hex-A-Gone™ CR Make-up (HG 106)

Provides the chromium salts necessary for a solution. Make-up can be used to replenish chrome if

Complexor levels are low. In this case, CR Makeup may be used in place of CR Maint. Do not use if

Complexor levels are normal.

Hex-A-Gone™ Salts (HG 116)

Provides the salts required to operate the system. Hex-A-Gone™ Salts are depleted when operating the

bath. Regular analysis and additions of this product are required. Do not add salts if the specific gravity

exceeds 1.24 g/L.

Hex-A-Gone™ Cr Maint. (HG 100)

Provides the correct balance of chromium metal and complexors to maintain the bath. Hex-A-Gone™ Cr

Maint. must be added on an amp-hour basis.

Hex-A-Gone™ 1020 Carrier (HG140)

This maintenance additive is fed on an amp-hour basis to maintain all the brightening and complexing

agents in the bath. It is fed in combination with Hex-A-Gone™ Catalyst. This additive replaced the

prior existing 1020 BC Maintenance. Use Hex-A-Gone™ 1020 Carrier to improve deposit brightness.

DecoTri MS (PPS30553)

Reduces surface tension, prevents gas streaks, and improves HCD range. DecoTri MS can be added on

an amp-hour basis. It is controlled by surface tension analysis.

Hex-A-Gone™ Whitener (HG 110)

Hex-A-Gone™ Whitener is contained in 1020 Carrier. It helps to maintain the characteristic color of

the deposit. Hex-A-Gone™ Whitener should only be added at the direction of Pavco technical personnel.

Hex-A-Gone™ Catalyst (HG 114)

Hex-A-Gone™ Catalyst controls the deposition rate. Typical addition is 0.025-0.10%. Extra Catalyst

will be needed in presence of zinc contamination. Add 0.1% Hex-A-Gone™ Catalyst at 20 ppm Zinc.

Catalyst must be added on an amp-hour basis. Excess Catalyst can cause hazing.

5


Hex-A-Gone™ Extender (HG 101)

Hex-A-Gone™ Extender should only be added at the direction of Pavco technical personnel. This additive

will improve LCD coverage of the chrome. It will tend to darken the deposit with overuse, so use

minimally in 0.1% increments.

Hex-A-Gone™ Complexor (HG 115)

Hex-A-Gone™ Complexor should only be added at the direction of Pavco technical personnel. Low

Complexor can lead to poor throwing power and rapid formation of hexavalent chrome. Low Complexor

is indicated by a green solution color. High Complexor will cause reduced efficiency.

Analytical Procedures:

Hex-A-Gone™ Salts by titration

Equipment

• 5 mL pipette

• Magnetic stir plate and PTFE coated stir bar

• 150 mL beaker

• Calibrated pH meter

• Burette

Reagents

• Mannitol

• 1N sodium hydroxide

Procedure

1. Pipette a 5 mL bath sample into a 150 mL beaker.

2. Add 20 mL of deionized water.

3. Add a PTFE coated magnetic stir bar and mix solution on stir plate throughout the analysis.

4. Using a pH meter, adjust pH solution to 6.0-6.5 using either 1N sodium hydroxide or 1N sulfuric

acid. Record final pH.

5. Add 10 g of Mannitol (Excess Mannitol is necessary at all times).

6. Slowly titrate the solution with 1N sodium hydroxide until the recorded pH is reached. Add

additional Mannitol (2g) at the end. If pH drops, continue titrating.

7. If pH does not change, endpoint has been reached.

Calculation:

Hex-A-Gone™ Salts (g/L) = mL titrated X 49

Hex-A-Gone™ Salts by Specific Gravity:

Salt concentration can also be determined by Specific Gravity. Weigh 100 mL of plating solution on a

gram scale using a 100 mL volumetric flask. Be sure that flask is dry and determine tare weight of

empty flask. Subtract tare weight from total weight. Scale used must be accurate to +/- 0.1 grams.

Specific gravity = weight in grams / 100 mL

Use the chart below that is closest to your operating chrome concentration. If your Hex-A-Gone™ Salts

concentration by specific gravity does not match your Hex-A-Gone™ Salts by titration within 25 g/L,

consult a Pavco representative.

oz/gal Hex-A-Gone™ Salts = g/L Hex-A-Gone™ Salts /7.5

CAUTION: DO NOT ADD SALTS IF THE SPECIFIC GRAVITY EXCEEDS 1.25. Consult your Pavco

Representative if you Salts by titration are low and your specific gravity is high.

Hexavalent Chrome Test for Hex-A-Gone™ 1020

Trivalent Chrome Solution (Qualitative)

Summary

This procedure determines whether hexavalent chrome is being produced at the anodes. This helps

determine anode quality as well as proper additive concentrations in solution.

Equipment

• 250 mL Erlenmeyer flask

• 1 mL pipette

• 50 mL graduated cylinder

Reagents

• Diphenylcarbazide, 0.5% in acetone

• Sulfuric acid, 50%

• Distilled or Deionized water (DI)

Procedure

1. Add 90 mL of DI water to a 250 mL Erlenmeyer flask.

2. Add 10 mL of 50% sulfuric acid with a graduated cylinder.

3. Add 1 mL diphenylcarbazide indicator solution. Observe for pink color. If solution is pink,

discard and wash all glassware before returning to step 1.

4. If solution is not pink after Step 3, pipette 1 mL of trivalent chrome solution into the flask.

5. Observe for the development of a pink color. Pink indicates presence of hexavalent chrome.

A barely distinguishable pink color indicates 20-50 ppm of hexavalent chrome.

Opaque pink/red indicates in excess of 500 ppm hexavalent chrome.

Notes:

• Take care not to contaminate diphenylcarbazide indicator solution with chromium solution.

Discard the indicator if contaminated. A colorless solution after step 3 demonstrates clean

indicator, glassware and reagents.

• Test the trivalent chrome plating bath immediately after sampling the bath. Any hexavalent

chrome generated at the anodes will rapidly react with bath additives and give false negative

results if sample is allowed to sit idle.

• Check the bath after 1, 4, and 8 hrs of production. Positive hex chrome tests can indicate a

defective anode coating. Consult your Pavco representative. Pink color in 1-4 hours will require

corrective action.

• If hexavalent chrome is present, check Hex-A-Gone™ Complexor levels. Adjust as needed in 2

g/L increments. Check feed rate for Hex-A-Gone™ 1020 Carrier and Hex-A-Gone™ Catalyst to

confirm optimum feed rate. Check contact on anodes and inspect for damaged coating. Check

anode current density and increase anode area. Send anodes to Pavco lab for coating thickness

testing. Send anodes out for recoating.

Hull cell analysis

Equipment

• 10 Amp rectifier

• Heated hull cell

• Polished brass panels

• Stainless steel beaker

• Hot plate

• Stainless steel tongs

• Alkaline electrocleaner (Clean-R-2002) 8 oz/gal (60 g/L)

• 5% Sulfuric acid in 500 mL glass beaker

• Thickness tester, XRF or Kocour /equivalent destructive thickness tester

1. Heat cleaner in a stainless steel beaker to 140˚F (60˚C). Attach anode lead (+) from rectifier to

stainless steel beaker. Use stainless tongs connected to the cathode lead (-) to clean a bright

brass panel cathodically at 10 amps for 20-30 seconds. Rinse in clean water.

2. Immerse in 5% sulfuric acid for 5-10 seconds, agitate.

3. Rinse. Ensure panel has a water break free appearance. If not, repeat cleaning process or

change cleaner.

4. Place panel in preheated hull cell. Solution must be maintained at actual bath operating

temperature in order to be representative of actual plating conditions.

5. Run a 5 amp, 3 minute hull cell panel.

6. Measure thickness at 1.7 cm, 3.9 cm, 6.1 cm, and 7.9 cm from left edge of panel. If using x-ray

testing, ensure machine is calibrated for chrome over brass. If it is not calibrated for chrome

over brass, then panel must be nickel plated before running the chrome hull cell. Destructive

tester usually require nickel plated panels.

Note: Bright brass panels are preferred over dull panels, as they allow easy observation for chrome

deposit variations such as dullness.
