Product Specification


Technical Data
Carboline Carboguard 893
Volume Solids: 77% +/- 2%
Theoretical Coverage Rate: 30.3 m²/l at 25 microns
30.3 m²/l at 25 microns
10.1 m²/l at 75 microns
5.1 m²/l at 150 microns
Allow for loss in mixing and application.
Dry Film Thickness: 76 microns per coat
102 - 152 microns per coat
76 - 150 microns for mild environments and as an intermediate coat over zinc rich primers.
102-152 microns for more severe environments.
Do not exceed 250 microns in a single coat. Excessive film thickness over inorganic zincs may increase damage during shipping or erection.
Dry Temperature Resistance: Continuous: 93°C
Non-Continuous: 121°C
Discolouration and loss of gloss is observed above 93°C
Primer: Self-priming. May be applied over organic and inorganic zinc rich primers. A mist coat may be required to minimize bubbling over zinc rich primers.
Topcoat: May be coated with acrylics, epoxies, alkyds, or polyurethanes depending on exposure and need.
VOC Values: As Supplied: 195 g/l
Thinner 2: 16 oz/gal = 261 g/l
Thinner 230: 13 oz/gal = 252 g/l
Thinner 33: 32 oz/gal = 329 g/l

These are nominal values and may vary slightly with colour

*Maximum thinning for 250 g/l restricted areas is 12 oz/gal with Thinner 2, and 11 oz/gal with Thinner 33 or Thinner 230. Use Thinner 76 where non photo chemically reactive solvents are required (up to 11 oz/gal)

Flash Point: Part A: 16°C
Part B: 15°C
Limitations: Not recommended for immersion service
Shelf Life: Part A: Min. 36 months at 24°C
Part B: Min. 24 months at 24°C

0-90% Relative Humidity



Drying Times


Curing Schedule
Surface Temp Dry to Recoat Dry to Topcoat Dry to Touch Maximum Recoat Time with Acrylics Maximum Recoat Time with Epoxies Maximum Recoat Time with Polyurethanes
4°C 24 Hours 72 Hours 6 Hours 14 Days 30 Days 90 Days
10°C 16 Hours 24 Hours 5 Hours 14 Days 30 Days 90 Days
16°C 12 Hours 16 Hours 4 Hours 14 Days 30 Days 90 Days
24°C 3 Hours 4 Hours 2 Hours 14 Days 15 Days 30 Days
32°C 3 Hours 4 Hours 2 Hours 14 Days 15 Days 30 Days



  • These times are based on a 100 microns 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.
  • Excessive humidity or condensation on the surface during curing can interfere with the cure, can cause discolouration, and may result in a surface haze. Any haze or blush must be removed by water washing before recoating.
  • During high humidity conditions, it is recommended that the application be done while temperatures are increasing.
  • Recoat intervals may vary from those listed above when using under intumescent fireproofing products.
  • Consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for recommended cure times before applying Carboline intumescent products.
  • If the maximum recoat time is exceeded, the surface must be abraded by sweep blasting or sanding before the application of additional coats.
  • When cured below 10°C a slight softening is typically observed as the temperature rises above 10°C and is considered normal.



Surface Preparation


General

  • Surfaces must be clean and dry.
  • Employ adequate methods to remove dirt, dust, oil, and all other contaminants that could interfere with adhesion of the coating.

Steel

  • SSPC-SP6 with a 25-50 microns surface profile.
  • When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product.

Galvanised Steel

  • Prime with specific Carboline primers as recommended by Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected]
  • Refer to the specific primer’s product data sheet for substrate preparation requirements.
  • When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product.

Concrete or CMU

  • Concrete must be cured 28 days at 24°C and 50% relative humidity or equivalent.
  • Prepare surfaces in accordance with ASTM D42582 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete.
  • Voids in concrete may require surfacing.



Application Methods


Product Information
Mixing:

Power mix separately, then combine and power mix

DO NOT MIX PARTIAL KITS

A 30-minute “sweat-in” time is highly recommended for applications below 10°C and will improve cure response
Thinning: Spray: Up to 131.5 g/l (12%) w/ Thinner 2 or up to 106.8 g/l (10%) w/ Thinner 230
Brush: Up to 263 g/l (25%) w/ Thinner 33
Roller: Up to 263 g/l (25%) w/ Thinner 33
Mist coating: Thin up to 263 g/l with Thinner 2 or 33 in VOC restricted (2.8lb/gal) areas
May thin up to 48 oz/gal where VOC restricted levels are at 3.5 lb/gal (0.42 kg/l) for mist coat only. If necessary, use Thinner 230 only in hot (above 38°C) and windy conditions, to slow down the evaporation rate
Ratio: 1:1 Ratio (A to B)
Pot Life:

4 Hours at 24°C

Pot life ends when coating loses body and begins to sag

Pot life times will be less at higher temperatures

Thinning rates above 16 oz/gal will shorten the working time to 2 hours
Spray (General): This is a high solids coating and may require adjustments in spray techniques. Wet film thickness is easily and quickly achieved
Conventional Spray: Pressure pot equipped with dual regulators, 3/8” (0.95 cm) I.D. minimum material hose, 0.070” (0.18 cm) I.D. fluid tip and appropriate air cap
Airless Spray: Pump Ratio: 30:1 (min)
GPM Output: 3.0 (min)
Material Hose: 3/8” (0.38 cm) I.D. (min)
Tip Size: 0.017-0.021” (0.043-0.053 cm)
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller (General): Multiple coats may be required to obtain desired appearance, recommended dry film thickness and adequate hiding. Avoid excessive re-brushing or re-rolling. For best results, tie-in within 10 minutes at 24°C
Brush: Use a medium bristle brush
Roller: Use a short-nap synthetic roller cover with phenolic core



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 4°C 4°C 4°C 0%
Maximum 32°C 57°C 43°C 90%



  • 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 SDS for this product
  • Employ normal workmanlike safety precautions
  • Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas

Ventilation

  • When used as a tank lining or 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
  • User should test and monitor exposure levels to ensure all personnel are below guidelines. If not sure or if not able to monitor levels, Use MSHA/NIOSH approved supplied air respirator.
  • Refer to the product data sheet and safety data sheet in the attachments section above for further details.
