Product Specification


Technical Data
Carboline Carbozinc 858
Volume Solids: 62.3% +/- 2%
Total Zinc Dust in Dry Film: By Weight: 84%
Primer: Self-priming
Topcoats Can be top coated with epoxies, polyurethanes, acrylics and others as recommended by Rawlins on Tech - 0113 2455450 (option 2) or [email protected]
Theoretical Coverage Rate:

25.2 m²/l at 25 microns

12.6 m²/l at 50 microns

4.2 m²/l at 150 microns

Allow for loss in mixing and application
Dry Film Thickness: 51 - 152 microns per coat
Dry film thickness more than 8.0 mils (200 microns) per coat is not recommended
VOC Values: As Supplied: 318 g/l

Thinner 2: 12.8 oz/gal: 366 g/l

Thinner 33: 12.8 oz/gal: 370 g/l

These are nominal values.

Use Thinner 76 for projects requiring non-photochemically reactive solvents.

Dry Temp. Resistance: Continuous: 177°C
Non-Continuous: 204°C
Flash Point:

Part A: 14°C

Part B: 19°C

Zinc Filler: NA

Shelf Life:

Part A: Min. 12 months at 24°C

Part B: Min. 24 months at 24°C

Zinc Filler: 24 months at 24°C

0-90% Relative Humidity



Drying Times


Curing Schedule
Surface Temp Dry to Topcoat Final Cure
2°C 8 Hours 10 Hours
10°C 5 Hours 6 Hours
24°C 2 Hours 3 Hours
32°C 1 Hour 1 Hour



  • These times are based on a 50% relative humidity and 75 micron dry film thickness. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
  • Dry to touch at 24°C is 30 minutes
  • Specific topcoat products can be used in a much shorter re-coat interval. Contact Rawlins Tech - 0113 2455450 (option 2) or [email protected] on for recommendations
  • Maximum Recoat: Unlimited. Must have a clean, dry surface for topcoating. “Loose” chalk or salts must be removed in accordance with good painting practice



Surface Preparation


General

  • Remove all oil or grease from the surface to be coated with Thinner 2 or Surface Cleaner 3 (refer to Surface Cleaner 3 Instructions) in accordance with SSPC-SP1

Steel

  • SSPC-SP6 with a 25-75 micron surface profile
  • SSPC-SP2 or SP3 for touch-up



Application Methods


Product Information
Mixing: Power mix Part A completely. Then slowly sift in the zinc filler under agitation. Power mix Part B separately and add slowly to the mixture. Pour mixture through a 30 mesh screen
Do not mix partial kits
Tip: Sifting zinc through a window screen will aid in the mixing process by breaking up or catching dry zinc lumps
Thinning:

Normally not required but may be thinned up to 12.8 oz/gal (10%) with Thinner 2 or Thinner 76. In hot or windy conditions, may be thinned up to 12.8 oz/gal with Thinner 33

Use of thinners other than those supplied by Carboline may adversely affect product performance and void product warranty, whether expressed or implied

Ratio:

.80 Gal. Kit

  • Part A: .354 gallons

Condition Material Surface Ambient Humidity
Minimum 4°C 2°C 2°C 0%
Maximum 32°C 49°C 43°C 95%



  • Industry standards are for the substrate temperatures to be 3°C above the dew point
  • This product simply requires the substrate temperature to be above the dew point
  • Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate
  • Special application techniques may be required above or below normal application conditions



Health and Safety


Clean Up

  • Use Thinner 2 or Acetone
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

  • Read and follow all caution statements on this product data sheet and on the safety data sheet for this product and use personal protective equipment as directed
  • Employ normal workmanlike safety precautions

Ventilation

  • When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
  • The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
  • In addition to ensuring proper ventilation, appropriate respirators must be used by all application personnel

Caution

  • This product contains flammable solvents. Keep away from sparks and open flames
  • All electrical equipment and installations should be made and rounded in accordance with applicable local regulations
  • In areas where explosion hazards exist workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes
  • Refer to the product data sheet and safety data sheets in the attachments section above for further details.
