CAUTION : Careful, routine monitoring of pH is required for successful operation of Hex-AGone 1020. DO NOT ALLOW THE pH TO EXCEED 3.8.
Bath Makeup per 1000 gallons - 3785 liters
2. Heat the water to 110oF (50oC)
3. Add 2335 pounds (1060 kg) of Hex-A-Gone Salts.
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 and mixed, raise the solution level
to 90% of operating volume with de-ionized water. Then lower the pH of the solution to
1.8 with 50% sulfuric acid. Agitate the bath for 12 hours minimum to establish the
proper chromium complex. After the 12 hour period, raise the pH over a two hour
period to operating range with 45% potassium hydroxide. (low chloride grade)
6. Add 10 gallons (37.5L) of Hex-A-Gone BC Make Up, 5 gallons (18.9L) of Hex-AGone Brightener, 3 gal (11.4L) Hex-A-Gone 1020 BC Maintenance, and 2.5 gal
(9.5L) Hex-A-Gone Wetter
7. Add D.I. water to the final volume
8. Electrolyze the bath for up to 2 amp-hours/gallon (0.5 amp-hours/liter) as needed
before use. Confirm brightness and coverage by hull cell before production use.

Use routine additions of HAG 1020 BC Maintenance to maintain good coverage,
color, and thickness of the chromium deposit
•
Use routine additions of HAG CR Maintenance to maintain chromium levels. HAG
CR Make-up is normally only needed for new bath make-up or when HAG
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
Metallic contaminants MUST BE TREATED REGULARLY. Nickel in excess of 50
ppm or zinc in excess of 10 ppm can reduce the bath efficiency (slow down the
rate of deposition) as well as darken the deposit. Electrolyze the solution at 10
amps/ft2 (1 amp/dm2 ) to remove zinc, 15 amps/ft2 (1.5 amps/dm2 ) to remove
nickel. See also Hex-A-Gone Purifier. Total combined metallic contaminants
should be kept under 50 ppm in order to achieve “blue” color.
•
•
Iron in excess of 30 ppm can darken the deposit. Electrolyze the solution at 10
amps/ft2 (1 amps/dm2 ) to remove iron. See also Hex-A-Gone Purifier
•
When the rate of metallic contamination is high, Pavco recommends ion exchange
or an electrowinning cell for continuous electrolyzing. See also Hex-A-Gone
Purifier
•
Carbon filtration is recommended to maintain good color and efficiency. Use 2 - 4
pounds of granular activated carbon (1 - 1.5 kg) per 1000 gallons (4000 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 BC
1020 Maintenance, 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 require extra BC 1020 Maintenance (0.05-0.10%) to obtain desired plating
rate. BC Maintenance or Catalyst can be used for this purpose.

Hex-A-Gone 1020 Components and Functions
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
Maintenance. Do not use if Complexer levels are normal.
Hex-A-Gone BC Make-up (HG 108) (used only in makeup)
Provides the grain refiners and brighteners necessary for a solution makeup.
Hex-A-Gone Salts (HG 116)
Provides the salts required to operate the system. HAG 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 Maintenance (HG 100)
Provides the correct balance of chromium metal and complexors to maintain the bath. HAG
Cr Maintenance must be added on an amp-hour basis.
Hex-A-Gone 1020 BC Maintenance (HG 111)
Provides the correct balance of grain refiners and brighteners to maintain the bath. HAG BC
Maintenance must be added on an amp-hour basis. It must be added regularly to ensure
consistent performance.
Hex-A-Gone 1020
Hex-A-Gone Cr Make-up (HG 106) (used only in makeup)
Hex-A-Gone Wetter (HG 104)
Reduces surface tension and prevents gas streaks. Improves HCD range. HAG Wetter can
be added on an amp-hour basis. It is controlled by surface tension analysis.
Hex-A-Gone Brightener (HG 112)
Hex-A-Gone Whitener (HG 110)
HAG Whitener is contained in BC 1020 Maintenance. It helps to maintain the characteristic
color of the deposit. HAG Whitener should only be added at the direction of Pavco technical
personnel.
Hex-A-Gone Catalyst (HG 114)
HAG Catalyst is contained in BC 1020 Maintenance. HAG Catalyst should only be added at
the direction of Pavco technical personnel. Typical addition is 0.05-0.1%. Extra Catalyst will
be needed in presence of zinc contamination. Add 0.1% HAG Catalyst at 20 ppm Zinc.
Hex-A-Gone Extender (HG 101)
HAG 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 , so use
minimally in 0.1% increments.
Hex-A-Gone Complexor (HG 115)
HAG 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.
Plating Systems
HAG Brightener is contained in BC 1020 Maintenance. HAG Brightener should only be
added at the direction of Pavco technical personnel. Very low brightener can cause dull
deposits.

Analytical Procedures
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 required
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
Hex-A-Gone 1020
Hexavalent Chrome Test for Hex-A-Gone 1020
Trivalent Chrome Solution (Qualitative)
1. Add 90 mls DI water to a 250 ml Erlenmeyer flask.
2. Add 10 mls Sulfuric acid, 50%, with a graduated cylinder.
3. Add 1 ml diphenyl carbazide 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.
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 Hexagone Complexer levels. Adjust as needed
in 2 g/l increments. Check feed rate for HAG 1020 BC Maintenance to confirm optimum
feed rate. Check contact on anodes. Check anode current density and increase anode
area. Send anodes to Pavco lab for coating thickness testing. Send anodes out for recoating.
Plating Systems
A barely distinguishable pink color indicates 20-50 ppm hexavalent chrome
Opaque pink/red indicates in excess of 500 ppm hexavalent chrome

Analytical Procedures
1) Heat cleaner in a stainless steel beaker to 140F. (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 xray 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.
